The CTEL and GPS antenna splitter (A2/57) consists of the following components:
Active frequency splitter with GPS antenna amplifier
Coaxial socket for the CTEL and GPS roof antenna (A2/49)
Coaxial socket for a GSM CTEL

ANTENNA SPLITTER, FUNCTION - GF82.85-P-3107-04B
Model 163 with code 353
The CTEL and GPS antenna splitter (A2/57) has the following functions:
Separating the signals received from the CTEL and GPS roof antenna (A2/49) :
The GSM and GPS signals are received by the antenna splitter via an antenna lead and leave the CTEL
and GPS antenna splitter (A2/57) via two separate coaxial cables. In addition the GPS signals are
amplified.
Decoupling the GPS receiver from the GSM telephone transmitter:
It must be ensured that the telephone transmitter signals do not reach the GPS receiver. The CTEL and
GPS antenna splitter (A2/57) allows them to pass only in the direction of the roof antenna.

The CTEL and GPS antenna splitter (A2/57)has the following functions:
Separating the receiving signals from the CTEL and GPS roof antenna (A2/49) :
The GSM and the GPS signals are received along an antenna cable at the antenna splitter and leave the
CTEL and GPS antenna splitter (A2/57) in two separate coaxial cables. The GPS signals are
additionally amplified.
Decoupling the GPS receiver from the transmitter of the GSM cellular telephone:
The transmission signals of the cellular telephone must not reach the GPS receiver. They are passed
through by the CTEL and GPS antenna splitter (A2/57) only in the direction of the roof antenna.

RISK OF DEATH, RISK OF EXPLOSION/RISK OF FIRE, RISK OF INJURY & RISK OF POISONING - AS82.10-Z-0001-01A
Do not come into contact with parts that are under high voltage. Persons with active electronic implants
(e.g. heart pacemakers) must never work on xenon headlamps. Switch off entire lighting system. Wear
insulated safety shoes, safety glasses and protective gloves. Remove highly inflammable materials from
the hazard area. Ensure sufficient ventilation in the working area.
Potential risks
Risk of death
Due to the high voltages involved, contact with live components at the xenon headlamps could be life
threatening!
Electric shocks can cause fibrillation of the heart or even cardiac arrest.
In addition, respiratory muscles may cramp up and result in respiratory failure.
Serious, possibly life-threatening, brain function disruptions are also possible.
It ma
y take a few minutes for the consequences of an electrical shock to manifest themselves.

Risk of explosion/risk of fire
Highly flammable materials in the vicinity of damaged, energized xenon bulbs may result in explosion or cause
fires.
Risk of injury
UV light may escape when operating xenon bulbs not properly installed in the xenon headlamps. This UV light
may cause damage to the eyes (conjunctival infection) and to skin burns (sunburns) if skin is unprotected.
In both intact or faulty xenon headlamps, hot or glowing components may cause serious burn injuries if they
come into contact with unprotected skin or eyes.
Glass splinters produced by the destruction of xenon bulbs may cause cut injuries in unprotected skin and
unprotected eyes.
Risk of poisoning
When xenon bulbs are destroyed, serious health problems may be caused if the mercury vapors produced are
inhaled or if mercury compounds or toxic salts are ingested or absorbed through the skin. Possible
consequences include nausea, vomiting and gastrointestinal disruptions as well as degradation of the kidneys
and the central nervous system. Skin and eye damage may also result.
Safety precautions/instructions
Persons with electronic implants (e.g. pacemakers) must never work on xenon headlamps.
Wear safety shoes (with rubber soles).
Prior to working on xenon headlamps (e.g. replacing parts, hooking up test equipment, etc.), the complete
lighting system must be switched off and the xenon headlamps must be disconnected from the on-board
electrical system.
If the xenon headlamps are switched on, never touch components under high voltage.
If the xenon headlamps are switched on, maintain a clearance of at least 30 mm to components under high
voltage.
Avoid all contact with hot components.
Wait at least 3 min after switching off xenon bulbs before touching them.
Do not damage or destroy xenon bulbs.
Safety precautions/instructions
Never operate xenon bulbs unless they are properly installed in xenon headlamps with UV-absorbing
headlamp lenses.
Keep all highly flammable materials away from working area.
Wear suitable protective gloves and safety glasses.
Ensure that the workplace is sufficiently ventilated.

Consult a physician immediately.
Always consult a medical service or physician after administering first aid.
INJURY HAZARD FROM PINCHING AND CRUSHING, IN EXTREME CASES EXTREMITIES CAN EVEN BE CUT OFF
WHEN CAUGHT IN WINDSHIELD WIPER MECHANISM. - AS82.30-Z-0001-01A
Always remove ignition key before working on windshield wiper mechanism.
Injury hazard
When working in the area of the windshield wiper mechanism with the ignition key in position "1" or "2" the
wiper arm or wiper linkage can be pushed out of its end position and start running unintentionally . This can
result in severe injuries by cutting, pinching or crushing body parts.
Rules of behavior/protective measures
Always remove ignition key before working on windshield wiper mechanism.
Secure operating range of mechanism against reaching in.
Keep sufficient distance away from moving parts.
Supervise hazard area.
Wear tight fitting clothing and hair net.
