England
Hand Held Products shall not be liable for use of our product with equipment
(i.e.,power supplies, personal computers, etc.) that is not CE marked and does
not comply with the Low Voltage Directive.
Pacemakers, Hearing Aids and Other Electrically Powered Devices
Most manufacturers of medical devices adhere to the IEC 601-1-2 standard. This
standard requires devices to operate properly in an EM Field with a strength of
3V/m over a frequency range of 26 to 1000MHz.
The maximum allowable field strength emitted by the Dolphin is 0.3V/m according
to Subpart B of Part 1 of the FCC rules. Therefore, the Dolphin RF will have no
effect on medical devices that meet the IEC specification.
Microwaves
The radio in the Dolphin RF terminal operates on the same frequency band as a
microwave oven. Therefore, if you use a microwave within range of the Dolphin
RF terminal you may notice performance degradation in your wireless network.
However, both your microwave and your wireless network will continue to
function.
•
•
• 10
•
•
•
The Dolphin Batch terminal does not contain a radio, and therefore, is not affected
by microwave ovens.
Batteries
The following are general guidelines for the safe use and disposal of batteries:
• Use only the battery supplied with your Dolphin or a replacement battery
supplied, recommended, or approved by Hand Held Products, Inc.
• Replace a defective battery immediately as it could damage the Dolphin
terminal.
• Never throw a used battery in the trash. It contains heavy metals and should be
recycled according to local guidelines.
• Don’t short-circuit a battery or throw it into a fire. It can explode and cause
severe personal injury.
• Excessive discharge damages a battery. Recharge the battery when your
Dolphin indicates low battery power.
• Although your battery can be recharged many times, it will eventually be
•
depleted. Replace it after the recommended usage period (about 600 charge
cycles for the 2700 mAh NiMH battery) or if the battery is unable to hold an
adequate charge.
If you are not sure the battery or charger is working properly, please send it to
Hand Hand Products or an authorized Hand Held Products service center, for
inspection.
The Dolphin handheld computer meets or exceeds all applicable standards and
has been manufactured to the highest level of quality.
Care and Cleaning of the Dolphin
When needed, clean the image engine window and the LCD display with a clean
non-abrasive, lint-free cloth.

2 Charging the Main Battery and Backup Battery
WARNING Use only 2700 mAh NiMH battery packs provided by Hand Held Products. The
use of any other battery pack in the Dolphin terminal will void your warranty and may result
in damage to the Dolphin terminal or battery.
The terminal’s NiMH battery is shipped discharged of all power so you must
charge it before using it for the first time. To charge the main battery pack:
1. Place the main battery pack in the Dolphin 7400 terminal.
2. Place the terminal in the terminal well of the Dolphin HomeBase™. Time to
Charge: 3.5 hours for the main battery; 8 hours for the back-up battery
As the main battery pack charges, the internal back-up battery also charges. For
the initial charging cycle, it is recommended that the terminal be charged for
approximately 8 hours to allow adequate charging time for the back-up battery.
Not doing so may result in the terminal becoming unstable should the unit lose
power and the back-up battery is required. The back-up battery maintains the
RAM and clock when the NiMH main battery pack is discharged or removed from
the terminal.
For maximum battery life, you must service, or deep cycle, the main battery pack
twice before initial use. It is also recommended that you service the battery once
per month. Refer to the section on Battery Management in Chapter 3 for further
information.

There are two batteries in the Dolphin:
Internal NiMH Backup Battery Located inside the Dolphin, this battery backs
up the RAM and clock when the NiMH main battery is discharged or removed
from the terminal. The internal backup battery is not user replaceable.
NiMH Battery Pack The battery pack is the primary power source for operating
the Dolphin terminal.
Internal NiHM Backup Battery
The Dolphin’s internal backup battery prevents the terminal from being reset if you
need to remove and replace the main battery pack. The battery retains RAM data
and allows the real-time clock to remain operational for up to 30 minutes when the
battery pack is removed. For the initial charging cycle, it is recommended that the
terminal be charged for approximately 8 hours to allow adequate charging time for
the back-up battery. Not doing so may result in the terminal becoming unstable
should the unit lose power and the backup battery is required.
If the backup battery becomes discharged of power after the initial charge cycle, it
will require a minimum of 5 hours of charging time to perform and maintain the
system as described above.
The internal backup battery is charged by the Dolphin’s main battery pack. If the
terminal is left without the main battery pack for more than 30 minutes, the internal
backup battery needs to be recharged.
Note: Data and programs stored in FLASH remain safe even if the internal backup
battery fails. However, you must reset the real-time clock using the Windows CE
Time and Date function.
Follow these guidelines to maximize the life of the Dolphin’s backup battery:
•
•
Keep a charged NiMH battery pack in the Dolphin. The internal battery will prematurely
discharge if there is not at least a partially charged battery in the terminal.
Put the Dolphin in the HomeBase when the terminal is not in use.
Main Battery Pack
The 3.6V, 2700 mAh Nickel-Metal-Hydride (NiMH) battery pack is the primary
power source for the Dolphin. Other NiMH batteries may be approved by Hand
Held Products to work with your Dolphin. Contact Hand Held for more
information.
The 2700 mAh NiMH battery is designed to operate in a temperature range of -10
to 50 ° C (14 to 122° F). For maximum performance, charge the batteries between
10 and 35 ° C (50 and 95° F).
Managing Battery Power
Data and files saved on the Dolphin 7400 terminal may be stored in RAM so it is
important for you to maintain a continuous power supply to the terminal. When the
main battery pack becomes low, the Low Battery Charge icon will appear in the
notification tray at the bottom of the screen. The Critical icon will appear when the
battery is critically low. There is also a Low Battery icon that will appear when the
back-up battery is low.
•
•
•
•
•
31 •
Letting the back-up battery become fully discharged will cause you to lose all
data. Therefore, you should keep a charged battery pack in the Dolphin at all
times to conserve the internal back-up battery. When you remove a battery pack,
insert another charged pack in the Dolphin. The internal battery will prematurely
discharge if there is not at least a partially charged battery in the terminal.
A battery status indicator will display in the notification tray when the battery is low
or critically low. If there is no indicator, the battery is adequately charged.
If the main battery is low and the terminal is in sleep mode, pressing the ON/
SCAN button will not wake up the Dolphin terminal; you must replace the spent
pack with a fully charged battery.
Using the Power Control Panel
The Power control panel displays information about current battery status and
allows you to set options that can conserve battery power.
There is also a battery usage indicator displayed. This indicator represents the
total cumulative time that the current main battery pack has been in use. If the
main battery is replaced with a different battery pack, the indicator will reset to
0:00. (If the main battery is removed and then the same battery placed back into
the terminal, the counter will not reset as it is tracking cumulative time on a
particular battery - each battery is uniquely identified by a serial number). Also, if
the terminal is placed in a HomeBase and is running on external power, the
indicator will cease counting. When the terminal is removed from the HomeBase,
the timer will resume.
To open the Power control panel:
Touchscreen-equipped terminals:
1. Tap the Start button, tap Settings, and then tap Power. If the power plug icon is on the
task bar, double-tap it.
2. Tap the Battery or Power Off tab.

Servicing the Battery Pack
For maximum battery life, you must service, or deep cycle, the battery twice
before initial use. It is also recommended that you service the battery once per
month. To deep cycle, insert the battery into the Dolphin 7400 QuadCharger or
use the Battery Conditioning Utility.
The Battery Conditioning Utility is used to condition or deep cycle a battery in the
Dolphin 7400 terminal. The discharge/charge cycle will minimize battery memory
effects and ensure the battery data is correct. A complete discharge/charge cycle
may take up to 15 hours for a fully charged battery. The actual cycle time will vary
depending on the battery state when the cycle was initiated.
Note: To run the Battery Conditioning Utility, the Dolphin 7400 terminal must have
the latest mainboard hardware or it will indicate an error as shown below. If you get
this error, contact Application Support for assistance.

Charging the Battery Pack
You can charge the Dolphin’s main battery pack with one of the following
methods:
•
•
Placing the battery pack in the Dolphin 7400 terminal and then placing the terminal in the
terminal well of the Dolphin HomeBase.
Placing the battery pack in the Dolphin 7400 Quad Battery Charger.
Storing Batteries
To maintain top performance from batteries, follow the guidelines below when
storing them:
Avoid storing batteries outside of the specified range of -4 to 104° F (-20 to 40°C)
or in extremely high humidity.
For prolonged storage, do not keep batteries stored in a charger that is connected
to a power source.
During long-term storage, battery deactivation may tend to occur which may
cause charging to stop early during recharging after storage. This issue can be
handled by charging and discharging the battery several times. Also, the first
charging after prolonged storage may yield a lower than normal capacity. While
this will vary depending on the storage conditions, charging and discharging the
battery several times will almost completely restore capacity.

wireless LAN solutions. Direct Connect TN Client software is a thick-client solution
that connects Dolphin 7400 RF computers directly to host applications via
TN3270, TN5250 or TNVT terminal emulation using industry-standard TCP/IP
protocol. Another option is a three-tier client server solution, or thin-client
implementation, for 3270, 5250 and VT100/220 terminal emulation that uses a
Universal Gateway. The Gateway establishes communication to a host such as
an AS400 and maintains communication to both the Dolphin 7400 RF terminal
and the host.
Thick-Client Terminal Emulation
PowerNet TN Client (telnet client) software allows the Dolphin 7400 RF terminal to
communicate directly with applications running on AS/400, ES/9000, HP/6000 or
other hosts connected to an Ethernet backbone and that support TCP/IP. The
TNVT, TN3270, and TN5250 emulations use TCP/IP to communicate from the
•
•
•
•
•
51 •
Dolphin 7400 RF terminal through the access point to the host. There is no
network controller or server.
Thin-Client Terminal Emulation
Hand Held Products’ thin-client terminal emulation solution uses a Universal
Gateway to provide host connectivity. The Universal Gateway connects to the
hosts such as AS/400, ES/9000 and HP/6000 via Ethernet and communicates to
the application via Ethernet for 3270, 5250 or telnet for DEC VT220 terminal
emulation environments.

HomeBase/IntelliBase
Hub of the System
As the hub of your Dolphin system, the HomeBase/IntelliBase
performs three important functions – power conditioning,
communications and storage. Two versions of the charging/
communications cradle are available -- the HomeBase for
communicating with PC-based equipment using a half duplex serial
mode and, the IntelliBase for communicating with devices such as
printers and modems without integrated IrDA protocol software.
Power Conditioning
The HomeBase/IntelliBase provides power to the Dolphin terminal to
enable the terminal to charge its battery.
Ir/IrDA Optical Communications
The infrared, or Ir communications port, on the HomeBase/IntelliBase
connects with the IrDA port on the Dolphin terminal. Reliable data
communications at speeds of up to 115k baud can be transmitted by
the HomeBase/IntelliBase. With no pins or contacts to break, Ir will
work reliably for years.
The IntelliBase infrared connection to the terminal uses IrDAcompliant hardware and software for a standard reliable connection.
Communications between the HomeBase and other devices occur a
half duplex serial mode. Half duplex refers to the transmission of data
in just one direction at a time.
The HomeBase/IntelliBase is not networkable.
Convenient Storage
The HomeBase/Intellibase is a safe and convenient storage
receptacle for the Dolphin terminal.

Powering the Dolphin Terminal
When seated in the HomeBase/IntelliBase, the Dolphin terminal receives the
power it needs to charge the battery and to run its internal circuitry.
The Dolphin terminal can be stored indefinitely in the HomeBase/IntelliBase
without damage to the terminal or the HomeBase/IntelliBase. Keep the
HomeBase/IntelliBase plugged in so that the Dolphin terminal’s battery pack stays
fully charged.
Charging A Dolphin Terminal
The HomeBase/IntelliBase supplies charging power to the Dolphin terminal so
that the terminal can monitor the charging of its battery pack. This charging
method protects the battery from being damaged by overcharging. Therefore, the
Dolphin terminal may be stored indefinitely in the HomeBase/IntelliBase without
damage to the terminal, the battery pack, or the HomeBase/IntelliBase.
To charge a Dolphin terminal, follow these steps:
1. Insert a battery pack into the Dolphin terminal.
2. Place the terminal, imager/laser engine window up and the LCD visible, in the Dolphin
Terminal Well of the HomeBase.
3. Let it glide down into the well until it stops.
4. Once the Dolphin terminal is properly seated, the Dock LED on the
HomeBase/IntelliBase will be solid GREEN.
Deep-Cycling Batteries
For maximum battery life, Hand Held Products recommends that you deep-cycle
(service) the battery twice before initial use and then, once a month thereafter.
Since the Dolphin 7400 HomeBase and Intellibase do not have deep-cycling
capabilities, it is recommended that you use the Battery Conditioning Utility
software or Dolphin 7400 Quad Battery Charger. See the Battery Management
section in Chapter 3 for more information.

Setting Up For Communications
The Dolphin terminal and HomeBase/IntelliBase support RS-232 communications
through the RS-232 Communications Port located on the back of the Dolphin
7400 HomeBase. The HomeBase/IntelliBase translates the RS-232 signals from
the host computer into infrared signals to communicate with the Dolphin Terminal.
The HomeBase/IntelliBase RS-232 interface allows the Dolphin terminal to
communicate to a personal computer, modem, or any standard RS-232 device
using a standard serial cable and communications software.
The IntelliBase infrared connection to the terminal uses IrDA 1.0-compliant
hardware and software for a reliable standard half duplex connection. This
protocol runs on the Dolphin 7400 terminal and also resides in the cradle. The
IntelliBase is for communications to devices without integrated IrDA protocol
software such as printers and modems. The HomeBase uses a non-IrDA or Ir
(Infrared) mode for half duplex serial communications.
HomeBase
The HomeBase is for users needing a half duplex serial communications
connection. Any device capable of using half duplex RS-232 communications can
be connected to the HomeBase for communications. To use this mode, set the
baud rate switches to the desired communications speed and the Ir-enable switch
to on (See Table 2).
IntelliBase
The IrDA 1.0 software stack is integrated into the IntelliBase to allow
communication between the cradle and devices such as modems or printers that
are not IrDA ready or do not communicate with a half duplex serial protocol. This
allows any full or half duplex RS-232 device to communicate through the
IntelliBase with no IrDA protocol software. See Table 2 for the baud rate switch
settings.
Follow these steps to set up the Dolphin HomeBase/IntelliBase and Dolphin
Terminal for communications:
1. Set up the HomeBase/IntelliBase.
2. Configure the Dolphin 7400 Terminal.
3. Follow the data transfer sequence as described by your application.
Setting Up The Dolphin HomeBase/IntelliBase
Set the Dolphin HomeBase/IntelliBase on a dry, stable surface, such as a desktop
near an electrical outlet. Be sure to provide enough workspace with good lighting
for the user to view and operate the Dolphin terminal while it is in the HomeBase/
IntelliBase.
Connecting the Cables
Connect the HomeBase/IntelliBase to the host computer or other device by
plugging an RS-232 serial cable into the RS-232 Communications Port on the rear
•
•

•
•
•
of the HomeBase. The wiring of your cable depends on whether the other device
is set up as a DCE (Data Communications Equipment) or DTE (Data Terminal
Equipment) device.
The HomeBase/IntelliBase Communication Port is configured as a DCE device.
To communicate with a DTE device such as a computer, use a standard (or
straight-through) RS-232 cable. To communicate with a DCE device, use either a
null modem adapter in line with a standard RS-232 cable, or a null-modem serial
cable.
You can make your own cables by following the pin configuration in the chart
below. To do so, you must determine if your host RS-232 device is 9-pin or 25pin, and whether it is configured as a DCE or DTE device.

Communicating with the Dolphin Terminal
To communicate with the Dolphin and any other devices connected to the
HomeBase/IntelliBase:
1. Insert the Dolphin into the terminal well of the HomeBase/IntelliBase. If the Dolphin is in
sleep mode, it will awaken into active state.
2. The DOCK LED on the HomeBase/IntelliBase will turn on. If the Dolphin does not turn
on, or the LED does not light up, make sure that it is properly seated in the terminal well
and that the power supply is properly connected to the HomeBase/IntelliBase and
plugged into a functioning AC outlet.
3. Start your application on the Dolphin terminal or the host computer. Data can then
begin transmitting between the terminal and the devices connected to the Dolphin
HomeBase/IntelliBase.
When data transfer begins, the COMM LED on the Dolphin HomeBase/IntelliBase
will blink red and green. If the HomeBase/IntelliBase will not communicate with
the Dolphin, check the port connections to ensure that the HomeBase/IntelliBase
is correctly configured.

Wall Mounting:
The HomeBase/IntelliBase also has two DIN rail (7.5 X 35mm) slots on the back
to allow for secure wall mounting of the unit if desired.
When using right-angle style RS-232 connector cable, the DIN rails may be
mounted directly to the wall. When using standard RS-232 connector cables, it is
recommended that the rails be mounted to the wall using a 25mm (1 in.) spacer to
allow for appropriate strain relief of the cables.
•
•
• 64

7400 QuadCharger
The Dolphin® 7400 QuadCharger provides intelligent battery
management for NiMH (Nickel Metal Hydride) Dolphin 7400 battery
packs.
The charger fully charges as many as four NiMH batteries in 2.5
hours. Charging slots work independently to control charging and
discharging of individual battery packs. The QuadCharger is
compatible with all models in the Dolphin® 7400 family of handheld
computers.
As battery packs charge, the charging circuitry uses a three-step
process that senses changes in temperature and voltage and drops
to a trickle charge when the packs are fully charged. This feature
allows the user to leave batteries in the charger indefinitely, which
maintains the batteries at peak capacity without damage. The
charger also resets and calibrates battery pack data to accurately
show battery status on the Dolphin display.
The QuadCharger also conditions and calibrates batteries for longer,
more consistent performance.

Charging Batteries In The QuadCharger
Follow these steps to charge batteries in the QuadCharger:
1. Set up the charger for use
2. Supply power
3. Insert batteries
CAUTION: Do not attempt to recharge any battery pack in the Dolphin 7400
QuadCharger that is not manufactured by HHP especially for this device. To do so
will void your warranty and could damage the Dolphin 7400 QuadCharger.
Setting Up The QuadCharger
The Dolphin 7400 QuadCharger should be setup on any dry, stable surface. DIN
rail slots on the bottom panel allow the charger to be wall or desktop-mounted for
easily adapting the unit to your environment.
The charger must be connected to a power source for any type of operation.
Supplying Power To The QuadCharger
CAUTION: Using a non-HHP power cord voids your warranty and could result in
serious damage to the Dolphin 7400 QuadCharger’s circuitry.
Locate the AC power cord that came with the Dolphin 7400 QuadCharger. Plug
the cord into the power supply connector on the back of the unit and, then plug the
power cord into a wall socket.
Press and hold the Power Switch for approximately one second, then release, to
turn on the Dolphin 7400 QuadCharger. The GREEN power LED will illuminate
and the charger will undergo a self-diagnostic test.
Inserting and Removing Battery Packs
To insert a battery pack, place the end of the battery without the locking tab into
the bottom of the charging pocket and snap the battery into place with a hinging
motion. Once the battery is properly seated, the orange status LED for that
particular pocket will illuminate.
For best results, battery packs should be at room temperature before recharging
them; temperature has a marked effect on charging. The recommended
temperature range is 50° to 95° F (10° to 35° C).
The LEDs indicate the charging status of batteries as described in the chart
shown on the next page:

To remove a battery pack, push the locking tab down and pull the battery out from
the charging pocket with a hinging motion.
Servicing The Battery Pack
To service battery packs, insert batteries into the charging pockets and press the
Condition button. The Condition LED will flash during the conditioning cycle. This
starts an automatic process where batteries are completely discharged and then
recharged to full capacity in eight hours. The Condition and Calibrate cycle resets
and calibrates battery data so that the user gets longer, more consistent
performance from the batteries. HHP recommends that battery packs should be
serviced, or calibrated once a month.
Because the Dolphin 7400 QuadCharger is accumulating battery pack information
during the entire Condition and Calibrate cycle, it is important not to remove the
battery until the cycle has been completed and the Condition LED is no longer
flashing. Batteries inserted after the “Condition and Calibrate” switch has been
depressed will receive a standard charge. The chart below describes the Status
LEDs during the Condition and Calibrate cycle:

Storing Batteries
To maintain top performance from batteries, follow the guidelines below when
storing them:
Avoid storing batteries outside of the specified range of -4 to 104° F ( -20 to 40°C)
or in extremely high humidity.
For prolonged storage, do not keep batteries stored in a charger that is connected
to a power source.
During long-term storage, battery deactivation may tend to occur which may
cause charging to stop early during recharging after storage. This issue can be
handled by charging and discharging the battery several times. Also, the first
charging after prolonged storage may yield a lower than normal capacity. While
this will vary depending on the storage conditions, charging and discharging the
battery several times will almost completely restore capacity.

Developing Applications
Applications for the Dolphin 7400 handheld computer are developed
in the Microsoft® Windows® CE environment.
Microsoft Windows CE is a compact, highly efficient, scalable
operating system designed for embedded systems and products. Its
modular platform allows developers flexibility to customize it for a
variety of small footprint and mobile 32-bit devices. Windows CE
supports various hardware peripherals, devices and networking
systems. These include keyboards, touchscreens, serial ports,
Ethernet connections, and storage devices, such as PC cards.
The Dolphin 7400 platform contains most components of the basic
Windows® CE kernel except for Pocket Word, Pocket Excel and
Pocket Outlook. The kernel is the central module of the operating
system. It is the part of the operating system that loads first, and it
remains in main memory. Because it stays in memory, it is important
for the kernel to be as small as possible while still providing all the
essential services required by other parts of the operating system and
applications. Data synchronization also is not supported as the
Dolphin 7400 terminal is not designed for use as a single target.
To get started with developing applications for your Dolphin 7400
terminal, see the Dolphin 7400 Developer’s Getting Started Guide.
