Wireless Installation Considerations
The D-Link wireless network camera lets you access your network using a wireless connection from virtually anywhere
within the operating range of your wireless network. Keep in mind, however, that the number, thickness and location of
walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary
depending on the types of materials and background RF (radio frequency) noise in your home or business. The key
to maximizing wireless range is to follow these basic guidelines:
1.Keep the number of walls and ceilings between the D-Link adapter and other network devices to a
minimum - each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position
your devices so that the number of walls or ceilings is minimized.
2.Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a
45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet
(14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead
of at an angle) for better reception.
3.Building Materials make a difference. A solid metal door or aluminum studs may have a negative effect on
range. Try to position access points, wireless routers, and computers so that the signal passes through
drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water
(fish tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.
4.Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that
generate RF noise.
5.If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and
home security systems), your wireless connection may degrade dramatically or drop completely. Make
sure your 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits
a signal even if the phone in not in use.

Recommendations for Setting Video for the Best Performance:
“Best performance” means the image refresh rate should be the fastest possible and the video quality should be the
best possible at the lowest network bandwidth possible. Three factors, Maximum frame rate, Fixed bit rate, and Fixed
quality in the Video Configuration page, are related to performance.
Recording settings for real-time motion images
To achieve a real-time visual effect, the network bandwidth should be large enough to transmit 20 image frames per
second (fps) or more. If you are on a broadband network over 1 Mbps, you can set Fixed bit Rate to 1000Kbps or
1200Kbps, or set Fixed quality to achieve the maximum frames. The maximum frame rate is 25 in 50Hz system and
30 in 60Hz system. If your network bandwidth is more than 384Kbps, you can adjust Fixed bit rate according to your
bandwidth and set the maximum frame rate of 25 to 30.
If the images vary dramatically in your environment, you may slow down the maximum frame rate to 20 to decrease
the transmitted data for better video quality. Since the human eye can not easily differentiate between 20 and 25 or 30
frames per second, the slower frame rate will not be noticed. If your network bandwidth is below 384 Kbps, you should
adjust the bit rate according to your bandwidth and experiment to allow for the best frame rate that can be achieved.
The faster frame rate in a slow network will blur the images. You may also try to choose 320x240 in size option for better
images or 640x480 for larger image size. Because the network has burst constraints and everyone’s environment is
different, any poor connection will impair normal performance.
Recording settings for clear identification for each image
To have the best video quality, you should set Fixed quality to detailed or excellent and tune the Maximum frame rate to
suit your network bandwidth. If you get some broken pictures in a slow network, you can set TCP protocol in Connection
type for a more accurate transmission but the received images may have a lag. Note that any slow connection with
multiple users will impair performance.
Recording settings to compromise between real-time and clear images
If you have a broadband network, set Fixed quality to Good image quality, or higher, instead of setting the Bit rate.
Otherwise, fix the bit rate according to your actual network speed and set the frame rate to 30. If the image quality is
low, select a lower frame rate above 15. If the image quality is still not improved, select a lower bit rate.

Video Channel Selection Area: The video channel selection area provides the IP addresses and location information of the connected
video channels for the user’s reference. You can select a video channel in this area and create a
schedule for it.
Primary Schedule: The Primary schedule consists of the day time-line, week time-line, begin time selector, end time selector,
and event mode settings.
Secondary Schedule: The Secondary schedule consists of event mode settings.
Operation Buttons: The operation buttons allow the user to manipulate the edited schedule of the selected video channel.
The scheduler can be closed from here.
The Functionalities of Configuration Components
The four main parts of the scheduler have been briefly described above. The four parts will be described in detail in
the following section.
Video Channel Selection Area
In this area you will select the video channel that you want to set a schedule for. Each video channel will display a
name, an IP address, and the location. Please note that when you switch between video channels in this area, the
changes in the schedule of the previous video channel will be saved automatically.

Primary Schedule
Schedule with Time Lines
There are two different time-lines: hour unit time-line and week unit time-line. You can make your own schedule by
plotting markers in all time-lines. These two time lines are associated with each other. That is, if you make changes in
one time-line, the corresponding changes will be applied with scale to the other three time-lines in the same schedule.
Before you begin, make sure that you select “Once” (page 85) if you want to choose the days to record on.
Week Time-Line
In the figure below, Week time-line is displayed. It includes the time-line, schedule information, and the selected day
in the week.
Marking/Unmarking the Recording Time on the Week Time-Line
The corresponding changes for the markers on the week time-line will be automatically added to the hour time-lines,
which is shown above. You can also mark and unmark the plotted bar by clicking and dragging with the left and the
right mouse button.

Using the Monitor Program
This section depicts, in detail, how to manipulate the monitor tool.
Connection of the DCS-2120
Once you have the privilege to connect to the DCS-2120, the cameras will automatically appear in the video area in
the order they are connected. Once you have set up the camera in the video channel, the color of the channel number
will turn green, indicating that the camera has been added to IP surveillance. If you do not set up the camera for the
video channel, the color of the channel number will be gray.
There is a unique light signal associated with each channel number. It indicates the status of the dedicated video
channel, which is depicted as follows:
Off: The video channel is not connected with any DCS-2120 yet.
Green: The green light means the DCS-2120 associated with this channel number is connected, and the video is monitored
in the video area.
Red: The red light indicates the video from this channel is recording into the video database. In this mode, you don’t have
to drag and drop the channel to the video area. This means that this application software supports real-time recording
with and without real-time monitoring for the dedicated video channel.
Blink: With the motion detection mechanism set in the DCS-2120, the light of the corresponding channel
will blink once the motion event is triggered.
If you do not want to monitor one video, you can drag and drop the video (in the video area) to the
trashcan in the common control area of the monitor program. The following section will demonstrate
the procedures for “drag and drop” step-by-step.

as shown below. In each display layout, only one window
can be assigned to a camera. Also, each camera must have
its own separate window when displayed. Once the video is
in a display window, it can be dragged and dropped to other
windows. If you drag one camera’s video to a window that
already has its own camera’s video, the two cameras will trade
display windows. Dragging and dropping is a very convenient
way to manipulate the video channels in the IP surveillance Software.

of the DO (Digital Output). With these features, you can monitor the remote sensor input from DI and also trigger the
camera by DO switch.
When the color of a DI/DO channel number is gray, that means the video channel has not yet
been connected to a camera.
Alert Message
If you have checked the box “Enable Motion Detect” or “Enable Digital Input” on the Camera
Configurations > Alert Settings screen, the alert message will show in the window shown
above. Once the alert, caused by motion detection or a digital input level change is triggered,
the alert message will be shown in this window. If there are more events than this window
can display, a scroll bar will appear.
The message format is described as follows:
“time”=>”alert type” #”channel number”(“win1”,”win2”,”win3”)
For example, the message “PM 02:41:00=>MO #1(0,1,1)” means that this is a motion
detection alert occurring at 02:41:00 PM in Motion Window 2 and Motion Window 3, for camera #1. If the message
“PM 02:41:56=>DI #1” is listed, that means there is an alert triggered by the DI, for camera #1, at 02:41:56 PM .

The items in the settings windows are:
Database Location: The most important item in the settings dialog is the database location setting. You must
set it to the directory that contains the surveillance database to make the program work
properly.
AVI File Location: This sets the directory where exported AVI files will be stored. Exported AVI files will be
stored in the sub-directory (camera name) under the directory you set here.
Snapshot File Location: This sets the directory where bitmap files will be stored when you use the snapshot to
export them. Exporting bitmap files will be stored in the sub-directory (camera name)
under the directory you set here.
Modulation Mode: The modulation mode cannot be changed. This depends on how you recorded the video
sequence in the monitor program. If you select the wrong mode, the video shown in the
display area will become distorted. If you have chosen the wrong modulation mode, you
may open the settings dialog again, change to the correct mode, and restart the playback
program. The display will now be normal.
Normal (Single Frame) Mode
While in the normal (single frame) display mode, you can change the video currently displayed by:
1) Changing the database path for retrieving another one in the settings dialog of “System Control” tool.
2) Changing the location selector to another location in control area.
3) Changing the playback method selector to “Full Range.”
4) Changing the playback method selector to “Time Period.”

Histogram Area
The histogram area in the normal display (single frame) mode only shows the events’ occurred time and the percentage
of motion detection with red bars. If you want to access the histogram area, you must change the area selection indicator
to the histogram area. You can mark one time interval you want to see with a color-inverted region by dragging your
mouse with the left button pressed (as shown below). When you release the left button, the color-inverted region will be
enlarged to the whole histogram area. This color-inverted region will be the new period the program is going to display.
If you change your mind and don’t want to see that period, you can cancel it by just pressing the right button of your
mouse with the left button still pressed. If you click on the left button without dragging it, the action will be the same as
clicking on the pull bar in the same x-axis position. That means the playback system will shift to the pointed time and
show video on the displaying frame. Besides, the dark regions in the histogram area mean there is no existing video
data in that interval. If you click on those regions, nothing will happen except a warning message will pop up.
Using Tools
In this section, the method of how to use the tools in the control panel (shown in the main playback window) will be
discussed.

Section 3 - Configuration
Location Selector
The location selector is a control that lets you select the camera you want to see (refer to the figure above). The location
name is the same as the camera name (text on video) unless you have specified otherwise.
Period Selector
Period selector provides you a precise way to choose the start time and the end time of a new period. The end time
must be later than the start time. After you provide the correct start and end time, clicking on the “Play” button in the
jog dial will play the new period in the display area with changing the period start and end time label. Besides, the pull
bar and histogram area will change, too. If the selected period is not present in the database, the data in the period
selector will change to the previous correct start and end time, and a warning message will be displayed.
Playback Method Selector
Since the program will record the previous start and end time in “Time Period” and “Events Preview” mode, whenever
you want to change the period selector to see the other periods, you must change the playback method selector to
the mode you want to use first. Otherwise, the period selector will revert back to the previous period set the last time
you changed the playback method selector.
Full Range: If you select this method, the database will be displayed from the beginning to the end of this location.
Any change in the period selector will have no effect except when you change this selector to “Time

Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The DCS2120 offers the following types of security:
• WPA-PSK (Pre-Shared Key)
• WEP (Wired Equivalent Privacy)
What is WEP?
WEP stands for Wired Equivalent Privacy. It is based on the IEEE 802.11 standard and uses the RC4 encryption
algorithm. WEP provides security by encrypting data over your wireless network so that it is protected as it is transmitted
from one wireless device to another.
To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When
using WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit
encryption requires a longer key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal
- using characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange – alphanumeric characters)
format. ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to
HEX for use over the network. Four keys can be defined so that you can change keys easily.
D-Link DCS-2120 User Manual
109
Section 4 - Security
What is WPA?
WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired
Equivalent Privacy).
The 2 major improvements over WEP:
• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys
using a hashing algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t been
tampered with. WPA2 is based on 802.11i and uses Advanced Encryption Standard instead of TKIP.
• User authentication, which is generally missing in WEP, through the extensible authentication protocol
(EAP). WEP regulates access to a wireless network based on a computer’s hardware-specific MAC
address, which is relatively simple to be sniffed out and stolen. EAP is built on a more secure public-key
encryption system to ensure that only authorized network users can access the network.
WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric
password between 8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key must
be the exact same key entered on your wireless router or access point.

Section 4 - Security
Setting Security
At this point it is highly recommended that you click on
the Configuration button on the Home screen, and then
the Tools tab to bring you to the Admin screen. Enter a
password for security purposes.
To ensure the highest security and prevent unauthorized
use of the Network camera, the Administrator has the
exclusive privilege to access the System Administration
settings to allow users entry and authorize privileges
for all users. The Network camera supports multi-level
password protection/access to the Network camera
that can be restricted to defined users who have a User
Name and User Password, which is assigned by the
Administrator.
The Administrator can release a public user name and password so that when remote users access the Network
camera they will have the right to view the image transmitted by the Network camera.
When the Network camera is used for the first time, it is highly recommended that the Administrator set the Administrator’s
Password to constrain user access to the Network camera since the Default settings are Null String (no password).
Once the Password is defined, only the Administrator has access to the management of the Network camera. This
procedure should be done as soon as possible since the security features of the Network camera will not be enabled
until the Administrator Password is defined.

Access the Router with Your Web Browser
If you have cable or DSL Internet service, you will most likely have a
dynamically assigned WAN IP Address. ‘Dynamic’ means that your
router’s WAN IP address can change from time to time depending on
your ISP. A dynamic WAN IP Address identifies your router on the
public network and allows it to access the Internet. To find out what
your router’s WAN IP Address is, go to the Status menu on your router
and locate the WAN information for your router (as shown on the next
Your WAN IP Address will be listed on the router’s
Status > Device Info page.

Section 4 - Security
Note: Because a dynamic WAN IP can change from time to time depending on your ISP, you may want to obtain a
Static IP address from your ISP. A Static IP address is a fixed IP address that will not change over time and will be more
convenient for you to use to access your camera from a remote location. The Static IP Address will also allow you to
access your camera attached to your router over the Internet.

Open Virtual Server Ports to Enable Remote Image Viewing
The firewall security features built into the DIR-655 router prevent users from accessing the video from the DCS-2120
over the Internet. The router connects to the Internet over a series of numbered ports. The ports normally used by the
DCS-2120 are blocked from access over the Internet. Therefore, these ports need to be made accessible over the
Internet. This is accomplished using the Virtual Server function on the DIR-655 router. The Virtual Server ports used
by the camera must be opened through the router for remote access to your camera. Virtual Server is accessed by
clicking on the Advanced tab of the router screen.
Follow these steps to configure your router’s Virtual Server settings:
1 Click Enabled.
2 Enter a different name for each entry.
3 Enter your camera’s local IP Address (e.g., 192.168.0.120 in the example in step 2 on page 122) in the
Private IP field.
4 Select TCP for HTTP port, both (TCP and UDP) for RTSP and both (TCP and UDP) for 5556 - 5559
ports.
5 If you are using the default camera port settings, enter 80 into the Public and Private Port section, click Apply.
6 Scheduling should be set to Always so that the camera images can be accessed at any time.

1 What is an Network camera?
The Network camera is a stand-alone system connecting directly to an Ethernet or Fast Ethernet network. It differs
from a conventional PC Camera, the Network camera is an all-in-one system with built-in CPU and Web-based
solutions providing a low cost solution that can transmit high quality video images for monitoring. The Network
camera can be managed remotely, accessed and controlled from any PC/Notebook over an Intranet or the Internet
from a Web browser.
2. What is the maximum number of users that can be allowed to access DCS-2120 simultaneously?
The maximum number of users that can log onto the Network camera at the same time is 10. Please keep in mind
the overall performance of the transmission speed will slow down when many users are logged on.
3. What algorithm is used to compress the digital image?
The Network camera utilizes MPEG-4 Simple Profile Mode image compression technology to provide high quality
images.
4. Can I capture still images from the Network camera?
Yes you are able to capture still images with the snapshot function from the software application CD supplied with
the Network camera or with the snapshot function on the Home page using an Internet browser.
5. Can the Network camera be used outdoors?
The Network camera is not weatherproof, and needs to be equipped with a weatherproof case in order to be used
outdoors (recommended).
6. When physically connecting the Network camera to a network what network cabling is required?
The Network camera uses Category 5 UTP cable allowing 10 Base-T and 100 Base-T networking.
7. Can the Network camera be setup as a PC-cam on a computer?
No, the DCS-2120 Network camera is used only on a wireless 802.11b/g, Ethernet, or Fast Ethernet network.
D-Link DCS-2120 User Manual
128
Section 5 - Troubleshooting
8. Can the DCS-2120 be connected to the network if it consists of only private IP addresses?
Yes, the Network camera can be connected to a LAN with private IP addresses.
9. Can the DCS-2120 be installed and work if a firewall exists on the network?
If a firewall exists on the network, port 80 needs to be opened for ordinary data communication. The DCS-2120
uses HTTP port and RTSP port to stream video data. These ports (or the ports you specify from the Advanced Tab
in the Configuration screen if you change the default ports) need to be opened in the firewall device. Please refer to
page 124 for more information.
10. Why am I unable to access the DCS-2120 from a Web browser?
If a router or firewall is used on the network, the correct ports for the DCS-2120 may not be configured on the
router or firewall. To correct the problem, you need to determine if the DCS-2120 is behind a router or firewall and
if the router or firewall is properly configured for the ports the DCS-2120 is using. Refer to page 124 for help in
opening the correct ports on a router or firewall for use with the DCS-2120.
Other possible problems might be due to the network cable. Try replacing your network cable. Test the network
interface of the product by connecting a local computer to the unit, utilizing a Ethernet crossover cable. If the
problem is not solved the Network camera might be faulty.
11. Why does the Network camera work locally but not externally?
This might be caused by network firewall protection. The firewall may need to have some settings changed in
order for the Network camera to be accessible outside your local LAN. Check with the Network Administrator for
your network.
Make sure that the Network camera isn’t conflicting with any Web server you may have running on your network.
The default router setting might be a possible reason. Check that the configuration of the router settings allow the
Network camera to be accessed outside your local LAN. Please refer to page 124 for more information.

12. I connected the Network camera directly to a computer with a cross-over cable Ethernet cable and
received the following Windows error upon running the Installation Wizard:
This Windows error will occur if the Network camera is connected to a computer that is not
properly configured with a valid IP address. Turn off DHCP from the Network Settings in Windows®
and configure the computer with a valid IP address, or connect the camera to a router with DHCP
enabled (see page 144).
13. Why does a series of broad vertical white lines appear throughout the image?
It could be that the CMOS sensor has become overloaded when it has been exposed to bright lights such as direct
exposure to sunlight or halogen lights. Reposition the Network camera into a more shaded area immediately as
prolonged exposure to bright lights will damage the CMOS sensor.
14. Noisy images occur. How can I solve the problem?
The video images might be noisy if the Network camera is used in a very low light environment. To solve this issue
you need more lighting.
15. The images appear to be of poor quality, how can I improve the image quality?
Make sure that your computer’s display properties are set above 256 colors. Using 16 or 256 colors on your
computer will produce dithering artifacts in the image, making the image appear to be of poor quality.
The configuration on the Network camera image display is incorrect. Through the Advanced > Image Setting
section of the Web management you need to adjust the image related parameters such as brightness, contrast,
hue and power line frequency for fluorescent light. Please refer to the Advanced > Image Setting section on Page
43 for detailed information.

Wireless Basics
D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless
connectivity within your home, business or public access wireless networks. Strictly adhering to the IEEE standard,
the D-Link wireless family of products will allow you to securely access the data you want, when and where you want
it. You will be able to enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals
instead of wires. Wireless LANs are used increasingly in both home and office environments, and public areas such
as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and
communicate more efficiently. Increased mobility and the absence of cabling and other fixed infrastructure have proven
to be beneficial for many users.
Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in
order to use servers, printers or an Internet connection supplied through the wired LAN. A Wireless Router is a device
used to provide this link.

What is Wireless?
Wireless or WiFi technology is another way of connecting your computer to the network without using wires. WiFi uses
radio frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or office
network.
Why D-Link Wireless?
D-Link is the worldwide leader and award winning designer, developer, and manufacturer of networking products.
D-Link delivers the performance you need at a price you can afford. D-Link has all the products you need to build your
network.
How does wireless work?
Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point
B. But wireless technology has restrictions as to how you can access the network. You must be within the wireless
network range area to be able to connect your computer. There are two different types of wireless networks Wireless
Local Area Network (WLAN), and Wireless Personal Area Network (WPAN).
Wireless Local Area Network (WLAN)
In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access
point has a small antenna attached to it, which allows it to transmit data back and forth over radio signals. With an
indoor access point as seen in the picture, the signal can travel up to 300 feet. With an outdoor access point the signal
can reach out up to 30 miles to serve places like manufacturing plants, industrial locations, college and high school
campuses, airports, golf courses, and many other outdoor venues.

Wireless network is easy to setup, but if you’re installing it for the first time it could be quite a task not knowing where to
start. That’s why we’ve put together a few setup steps and tips to help you through the process of setting up a wireless
network.
Tips
Here are a few things to keep in mind, when you install a wireless network.
Centralize your router or Access Point
Make sure you place the router/access point in a centralized location within your network for the best performance. Try
to place the router/access point as high as possible in the room, so the signal gets dispersed throughout your home.
If you have a two-story home, you may need a repeater to boost the signal to extend the range.
Eliminate Interference
Place home appliances such as cordless telephones, microwaves, and televisions as away as possible from the
router/access point. This would significantly reduce any interfere that the appliances might cause since they operate
on same frequency.
Security
Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning
on the WPA or WEP security feature on the router. Refer to product manual for detail information on how to set it up.

Wireless Modes
There are basically two modes of networking:
•Infrastructure – All wireless clients will connect to an access point or wireless router.
•Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless network
adapters on each computer, such as two or more DCS-2120 wireless network Cardbus adapters.
An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect
to the wireless router or access point.

After you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from
a DHCP server (i.e. wireless router) automatically. To verify your IP address, please follow the steps below.
Click on Start > Run. In the run box type cmd and click OK.
At the prompt, type ipconfig and press Enter.
This will display the IP address, subnet mask, and
the default gateway of your adapter.
If the address is 0.0.0.0, check your adapter
installation, security settings, and the settings
on your router. Some firewall software programs
may block a DHCP request on newly installed
adapters.
If you are connecting to a wireless network at a
hotspot (e.g. hotel, coffee shop, airport), please contact an employee or administrator to verify their wireless network
settings.

Appendix B - Networking Basics
Statically Assign an IP Address
If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps
below:
Step 1
Windows® XP - Click on Start > Control Panel > Network Connections.
Windows® 2000 - From the desktop, right-click My Network Places > Properties.
Step 2
Right-click on the Local Area Connection which represents your D-Link network adapter and select Properties.
Step 3
Highlight Internet Protocol (TCP/IP) and click Properties.
Step 4
Click Use the following IP address and enter an IP address that is on the same subnet as your network or the LAN
IP address on your router.
Example: If the router´s LAN IP address is 192.168.0.1, make your IP address
192.168.0.X where X is a number between 2 and 99. Make sure that the number
you choose is not in use on the network. Set Default Gateway the same as the LAN
IP address of your router (192.168.0.1).
Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). The
Secondary DNS is not needed or you may enter a DNS server from your ISP.
Step 5
Click OK twice to save your settings.
