-Consult the dealer or an experienced radio/ TV technician for help.
Modes of operation
The following chapters describe the modes of operation that can be carried out by the
FS173NPM devices.
Remote keyless Entry
The Remote Keyless Entry (RKE) functions enable the user to control the central locking system
and other functions of a vehicle from a distance. It is always manually activated by pressing one
of the buttons on the device. When activated, the device will transmit a sequence of RF
messages. In RKE mode RF communication is processed in simplex mode. For some comfort
functions which are activated by holding the buttons pressed continuously, the devices respond
with RF transmission triggered by LF (125 KHz) message sent by the vehicle.

Keyless Entry / Keyless Go
Keyless Entry / Keyless Go functions allow the user control of the central locking system and
engine start / stop without manual operation of the key. For these functions the devices can be
woken up by a 125 KHz low frequency (LF) signal generated by the vehicle. For recognition of LF
signals the devices contain a set of 3 orthogonal sensor coils (LF antenna array) and a detection
circuit that is integrated in the main μC. For Keyless Entry / Keyless Go functions RF
communication takes place in half duplex mode.
Transponder mode
The transponder mode serves as ab backup means for deactivation of the immobilizer system if
the keyless go function is not available for any reason. In transponder mode, the device is
supplied from the magnetic field generated by the immobilizer system of the vehicle and
communicates with the vehicle using damping modulation. The nominal working frequency of
the transponder system is 125 KHz. No RF communication is used in transponder mode.
Therefore, the device does not generate or emit any RF energy in this mode.
