1. General Description of the RF Transmitter
The described system is a radio -frequency remote control (usually c alled Remote Keyless Entry
system) for central doors locking / unlocking destined to equip the Smart W451 car Iine.The
system components constituting the Smart W451 application are:
- The RF key with 3 or 4 buttons (doors locking / unlocking, trunk unlockin 9), including the
transponder function
- The SAM which integrates the RF receiver, and in which the remote control decoding is
done
. The immobiliser with an LF coil antenna.
The transmitter is used to transmit information tor locking or unlocking the vehic Is by a
unidirectional RF transmission line for normal remote operation by pressing a button Also is
implemented the function of the Immobilizer in the transmitter With a bidirectional LF —
transmission (passive).
In general the following lunctions are p rovtded.
Lock the car
Unlock the car
Unlock the boot |Id of the car
Panic alarm
Immobilizer (motorstart)

3. Power Supply
The transmitter is provided with 1 lithium battery (CR 2016) that gives a
power supply of +3V. The key is protected against polarity reversal due to wrong battery insertion
by mechanical means. The battery capacity covers the typical usage pattern of 10000 activation
during two years
