1. SYSTEM OVERVIEW
The RF remote control system consists of a remote key which is a RF
transmitter / receiver and a RF transmitter / receiver unit at the vehicle.
The Remote Key is used to transmit information for locking or unlocking
the vehicle (as also Trunk Lid/Approach Light/Panic /comfort open/Comfort
Close/Check vehicle status/Passive lock/passive unlock/passive start
operations) by a bidirectional RF transmission line for normal remote
operation by pressing a button.
If the telegram which was received form the vehicle unit is not corrupted the
vehicle unit will send an acknowledgement message to the Remote key. If
the acknowledgement message is not received by the Remote key, the
remote key will repeat the transmission at the second channel.
The RF transmitter/ receiver is mechanically integrated in the head of the
key.
2. POWER SUPPLY
The transmitter is provided with 1 Lithium battery (CR 2430) that gives a
tension of feeding of +3V.
The battery inversion is protected mechanically.
3. BUTTONS
All buttons are on the top side of the key housing. They are arranged in the
following way.
