Rhomb
The rhomb is programmed at position 5 of register 060. Application at disposal.
FFSK Emergency Call
If a FFSK telegram with status = emergency call is received, the loudspeaker is switched on, the
loudspeaker lamp flashes, the emergency call ID-code is stored and flashes on the display. As
long as an emergency call is displayed, the key pad is blocked (exception PTT). An emergency
call can be deleted by pressing the (#) key.
FFSK Decoder
The decoder 1 to 10 are coded in registers 020 to 029. The telegram detected is compared with
the decoder 1 coding and in case of positions being coded with 'F', any digit is accepted. If the
FFSK telegram has been identified as correct, the loudspeaker is switched on, the loudspeaker
lamp flashes, the FFSK acknowledgement is transmitted and the bell tone is started. No further
telegram check will be performed.
The decoder 2 is coded in register 007 (EEPROM 1). See section EEPROM 1 Programming Mode.
The telegram detected is compared with the decoder 2 coding and in case of positions being coded
with 'F', any digit is accepted. If the FFSK telegram has been identified as correct, the loudspeaker
and the handset are switched on, the loudspeaker lamp flashes and the bell tone is started. No further
telegram check will be performed. An acknowledgement is not transmitted.
FFSK Acknowledgement
After detection by decoder 1 the FFSK acknowledgement is transmitted. The acknowledgement
is coded in register 017. If no acknowledgement is required, position 4 of register 030 ... 039
is coded with '0'.
Register 030 ... 039 4. position
0 = no acknowledgement
1 = FFSK standard acknowledgement
2 = single tone 600 Hz for 300 msec
3 = ID code
4 = received ID code
5 = FFSK standard acknowled 5-tone acknowl.
