1. GENERAL DESCRIPTION OF THE RF TRANSMITTER
The RF remote control system consists of a RF transmitter and a RF receiver
mounted within the control unit. The RF transmitter is mechanically integrated
in the head of the key. This transmitter is used to transmit information for
locking or unlocking the vehicle by a unidirectional RF transmission line for
normal remote operation by pressing a button.
In general the following functions are provided:
- Lock the car
- Unlock the car
- Unlock the trunk of the car
- Panic Alarm
Immobilizer Transponder
When the key is operating as an immobilizer transponder, communication is
done over a "contact less interface" depending on strong magnetic coupling.
The transponder is the passive side of the link and there is no RF
transmission from it involved in any aspect.

2. POWER SUPPLY
The transmitter is provided with 1 lithium battery (CR1616) that gives a
power supply of +3V.
3. TYPICAL USAGE PATTERN (FOR EUROPE ONLY)
20 lock/unlock operations in 24 hours with complete transmission duration
of 10.0 seconds (500ms/operation)
2 power window up/down operations in 24 hours with transmission duration
of 10 seconds ( 5.0 seconds for 1 operation; max. value)
→ total transmission duration of 20 seconds within 24 hours
Transmitter ON 0.83 seconds / hour
Transmitter OFF 3599.17 seconds / hour
Duty Cycle: TON / T (ON+OFF) x 100% = 0.83/ 3600 x 100 % = 0.023 %
