Guidelines for Safe and Efficient Use
General
Since its introduction in the mid 1980s the mobile phone is one of the
most exciting and innovative products ever developed. Your phone can
help you to stay in touch with your office, your home, emergency
services and others.
Your mobile phone is a radio transmitter and receiver. When the phone
is turned on it receives and transmits radio frequency (RF) energy.
Depending on the type of mobile phone you have purchased, it operates
in different frequency ranges and employs commonly used modulation
techniques. The system that handles your call when you are using your
phone, controls the power level at which your phone transmits.
●
Antenna Care and Replacement
●
●
Exposure to Radio Frequency Energy
The International Commission on Non-Ionizing Radiation Protection
(ICNIRP), sponsored by the World Health Organisation (WHO),
published a statement in 1996 which sets limits for exposure to RF fields
from handheld mobile phone. According to this statement, which is
based on the available body of research, there is no evidence that mobile
terminals meeting the recommended limits can cause any adverse health
effects. All Ericsson telephones conform to the ICNIRP
recommendations, and international exposure standards, such as:
● CENELEC European Pre-standard ENV50166-2
● ANSI/IEEE C95.1-1992 (USA, Asia-Pacific)
If you want to limit RF exposure even further, you may choose to
control the duration of your calls and operate your phone in the most
power efficient manner.
Efficient Phone Operation
How to use your phone for optimum performance with minimum power
consumption:
● Hold the phone as you would any other telephone. While speaking
directly into the mouthpiece, angle the antenna in a direction up and
EN/LZT 126 1452 R2A
over your shoulder. If the antenna is extendable, it should be
extended during a call.
Do not hold the antenna when the phone is in use. Holding the
antenna affects call quality, may cause the phone to operate at a
higher power level than needed and shorten talk and standby times.
●
Do not bend the antenna since it is sensitive and since this will
reduce its performance.
Do not use the phone with a damaged antenna. Consult your manual
to see if you may change the antenna yourself. If so, use only an
Ericsson approved antenna. Otherwise, take your phone to a qualified
service center for repair. Use only the designated Ericsson antenna.
Do not use an antenna designed for any other type of portable
telephone than the telephone you have purchased. Unauthorized
antennas, modifications, or attachments could damage the phone and
may violate the appropriate regulations.
Driving
Check the laws and regulations on the use of telephones in the areas
where you drive.
If you are going to use your mobile phone while driving:
● Give full attention to driving.
● Use hands-free operation, if available.
● Pull off the road and park before making or answering a call if
driving conditions so require.
RF energy may affect some electronic systems in motor vehicles. In
addition, some vehicle manufacturers forbid the use of mobile phones in
their vehicles. Check with your vehicle manufacture’s representative to
be sure your phone will not affect the electronic systems of your vehicle.
v
Electronic Devices
Children
Most modern electronic equipment, for example, equipment in hospitals
and cars, is shielded from RF energy. However, RF energy from
telephones may affect some electronic equipment.
● Turn off your phone in health care facilities when regulations posted
in the areas instruct you to do so.
● Do not use your mobile phone near medical equipment without
requesting permission.
Mobile telephones may affect the operation of some implanted cardiac
pacemakers, equipment for people with hearing impairments and other
medically implanted equipment. Pacemaker patients should be aware
that the use of a mobile phone very close to a pacemaker may cause the
device to malfunction. Avoid placing the phone over the pacemaker, i.e.
in your breast pocket. When using the phone, place it at your ear
opposite the pacemaker. If a distance of 15 cm. is kept between the
phone and the pacemaker, the risk of interference is limited. Contact
your cardiologist for more information.
●
Do not allow children to play with your phone since they could hurt
themselves or others or accidentally damage the phone.
Blasting Areas
●
Turn off your mobile phone when in a “blasting area” or in areas
posted “turn off two-way radio” to avoid interfering with blasting
operations. Construction crews often use remote control RF devices
to set off explosives.
Potentially Explosive Atmospheres
Turn off your phone before boarding any aircraft.
Do not use it on the ground without crew permission
To prevent interference with communication systems, you must not use
your phone while the plane is in the air.
Turn off your phone when in any area with a potentially explosive
atmosphere. It is rare, but your phone or its accessories could
generate sparks. Sparks in such areas could cause an explosion or fire
resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not always,
clearly marked. They include fuelling areas, such as petrol stations,
below deck on boats, fuel or chemical transfer or storage facilities, and
areas where the air contains chemicals or particles, such as grain, dust,
or metal powders.
● Do not transport or store flammable gas, liquid, or explosives in the
compartment of your vehicle which contains your phone and
accessories.
Power Supply
Product Care
Aircraft
●
●
●
●
●
●
vi
Connect AC (Power supply) only to designated power sources as
marked on the product.
To reduce risk of damage to electric cord, remove from outlet by
holding onto AC adapter rather than cord.
Make sure the cord is located so that it will not be stepped on, tripped
over or otherwise subjected to damage or stress.
To reduce risk of electric shock, unplug unit from power source
before attempting any cleaning, then use soft cloth dampened on with
water.
●
●
●
●
Do not expose your mobile phone to moisture or extreme
temperatures.
Do not use any other accessories but Ericsson originals. Failure to do
so may result in loss of performance, fire, electric shock or injury,
and will void the warranty.
Do not attempt to disassemble the product. Doing so will void
warranty. This product does not contain consumer serviceable
components. Service should only be performed by Authorized
Service Centers.

The Dual Mode (GSM/DECT) Phone
The TH 688 is a dual mode phone. This means that you can use it both
as a GSM mobile phone and as a cordless phone in a DECT network.
Provided you have made the required settings, it will use the DECT
network whenever you are in reach of it, and the GSM network
whenever you are out of reach of the DECT network.
To be able to switch between a DECT network and a GSM network the
phone must be set to Auto mode. This is done in the NETWORKS menu.
In this menu you also have the possibility to set the phone to DECT
mode only or GSM mode only. If you do this, your phone will work as a
cordless phone or a GSM phone respectively.
GSM
The phone only searches for and connects to a GSM network. No DECT
calls can be made.
Note! When you are in DECT mode, the Networks menu looks the same
as in GSM mode, but the menus are handling the DECT network
instead. It is not possible to make any changes in the GSM network
when you are in DECT mode.
Handling the Networks
In the System mode menu, under the Networks menu, there are the
following options:
● Auto
● DECT
● GSM
The default setting is Auto.
Auto
When the phone is in Auto mode, your phone connects to a DECT
network if there is one within range. If the phone is not within range of a
DECT network, it will search for a GSM network instead
If you make a call in GSM mode and enter a DECT network area, the
phone will switch to DECT mode after you finish your call. However, if
you make a call in DECT mode and exit the DECT network area, your
call will be interrupted and lost.
DECT
The phone only searches for and connects to a DECT network. No GSM
calls can be made and no Short Message Services (SMS) are available.

Preparing Your Phone for Use
The SIM Card
When you become a subscriber of a GSM network you obtain a SIM
(Subscriber Identity Module) card.
Your SIM card is supplied with a security code or PIN (Personal
Identity Number) which you need in order to gain access to the phone
and GSM network.
The SIM card contains a computer chip that keeps track of your phone
number, the services you have ordered from your GSM network
operator and your phone book information.
Before you are able to use your phone the SIM card must be inserted
into the phone.
How to Insert the SIM Card
❺ Lock the card holder by sliding it towards
you.
The Battery
Your mobile phone is supplied with a nickel metal hydride battery. The
battery is not charged when purchased, however there may be enough
power to turn on the phone.
The battery must be attached to the phone before it can be charged.
How to Attach the Battery to the Phone
❶ Place the battery on top of the phone.
❶ Release the card holder by sliding the lid
away from you.
❷ Press until you hear a click.
❷ Open the holder.
How to Remove the Battery
Make sure that the phone is turned off before removing the battery.
2
❸ Slide the mini SIM card into the holder.
Make sure that the cut corner is top right.
❶ Press the locking catch on the bottom of the
battery.
❹ Fold down the card holder.
❷ Lift the battery up and away from the phone.
EN/LZT 126 1452 R2A
How to Charge the Battery
●
●
Connect the charger to the phone as illustrated in
the figure. You need to press hard to fit the plug
into the phone. The flash symbol on the charger
must face upwards.
Connect the charger to the mains.
The phone will now start charging the battery. To
indicate this the battery meter in the display is
continuously filled and emptied and the indicator light on top of the
phone shows a steady green light if the phone is turned on, or a
steady red light if the phone is turned off. When the battery is fully
charged, the battery meter in the display will show full.
Note! It is possible to use the phone while it is being charged. This will,
however, increase the charging time.
How to Disconnect the Charger
Disconnect the charger from the phone by pushing
the plug upwards, see figure, and then pulling it out.
The Low Battery Alarm
As a reminder that the battery soon needs recharging
or replacing, an alarm signal (a long beep) sounds
and the message Battery low appears for ten seconds in the display.
In addition, the indicator light on top of the phone starts blinking red. If
the phone is left on, the low battery alarm will be repeated several times
and, finally, the phone will turn itself off when the battery is no longer
able to power it satisfactorily. It is not possible to turn the phone on
again. Instead the battery must be recharged or replaced with a charged
one.
EN/LZT 126 1452 R2A

Turning On the Phone
❶ Press and hold down the NO key until you hear a click. If you have
inserted a SIM card in your phone, the display will prompt you to
enter your PIN code. If not, the display will read ‘SIM card not
present’.
❷ Enter your PIN code. The digits appear as * in the display. If you
make a mistake while entering your PIN code erase the faulty digit by
pressing the CLR key.
❸ Press YES.
If you have entered your PIN code correctly, you will be welcomed by
your phone. The phone will then search for a network.

You can now make and receive calls. This is called standby mode.
When you are not using the phone, the illumination of the display and
keypad is automatically turned off after 10 seconds. Pressing any key
will turn the illumination on again.
If the message Emergency calls only is displayed, you are within range
of a network but you are not allowed to use it. However, in an
emergency, you can call the international emergency number 112. See
chapter Making and Receiving Calls in GSM Mode, p. 7.
Connecting Your TH 688 to a DECT network
When you connect your TH 688 to a DECT network, the first row
displays the network’s identity. If the name and number exceed 10
characters, only the net name is shown.
4
When No Network is Displayed
If the message No network is displayed, there is no network within
range or the received signal is too weak. You have to move to obtain a
sufficiently strong signal.
The Display Language
The phone is normally, depending on SIM card, delivered with English
text in the display. To select a different language, see Personalizing
Your Phone, p. 16.

Preparing Your Phone for DECT Networks
In order to benefit in the best way possible from the dual mode
functions, make sure the following items have been programmed into
your phone. This is usually done by a network administrator. If
necessary, you can program it yourself.
Programming the sequences below will make your telephone distinguish
internal calls from external ones automatically when you are making
calls.
In some cases, when a phone number could be external or internal, the
phone will ask you to confirm whether the number you wish to dial is
external or internal.
PBX Prefix
Note! The section below only applies if you are connected to a company
DECT network, not to a Home Base Station.
The PBX prefix is the first few digits, common to all phone numbers in
a company switchboard, for example. You have to enter this prefix in
order for your phone to recognise internal numbers stored in your phone
book, thus dialling internally instead of externally.

Sending and Receiving Text Messages (GSM only)
The Short Message Service (SMS) allows you to send and receive text
messages. A message may contain up to 160 characters.
Text messages can be received when the phone is in standby mode,
when you are engaged in a call or when incoming calls are diverted to
another phone number. If the phone is turned off when somebody sends
a message to you, a message will be displayed when you turn on the
phone.
Note! This function may not be available in all networks.
The Messages Memory
When you receive a text message it can be read at once. However, the
message is automatically stored in the Messages memory in the phone
which allows you to read it later on.
A letter icon ( Mm ) is shown to the left at the bottom of the display, as a
reminder that one or more unread messages have been received.
The messages memory can hold up to 10 messages. When all memory
positions are occupied, the oldest read message will be overwritten
when a new message is received.
If the Messages memory becomes full with unread messages, new
messages will automatically be stored in the SIM card memory. If the
SIM card memory becomes full, the letter icon ( Mm ) starts blinking.
Messages will remain in the Messages memory until you erase them or
until you insert a different SIM card.
The SIM Card Memory
You can store important messages on your SIM card. This means that
you can retrieve them regardless of which phone you are using.
How to Set the Phone for Text Messaging
