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.

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

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.

Antenna Care and Replacement

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.

EN/LZT 126 1452 R2A v

Electronic Devices

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.

Aircraft

● 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.

Power Supply

●

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.

Children

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 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.

Product Care

●

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
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.

NETWORKS menu.

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.

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.

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

❶ Release the card holder by sliding the lid

away from you.

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
