Selective call 5 tones 5+5 / 6 tones 6+6
The selective call is a signaling system which uses audio tones in sequence
(usually "5 tones" selective calls) to call a specific station or group(s). In this
case you will only receive calls that have your selective call identification code
(a number) or calls sent to the group you belong to.
A selective call is sent by pushing MONITOR (fix call) and BACKLIGHT
(variable call). You can send a selective call also in 5+5 or 6+6 mode.
STATUS DIGIT: this function allows to send one status (programmed by
software) after a selective call.
ANI: it is set by pressing, releasing the PTT button, or both. This function allows
to send your own ID programmed by software.
For further details, please read the programming software instructions.
This function can be only set by the optional programming software (PRG08).
CTCSS / DCS
The CTCSS/DCS tones are a sort of 'access codes' and enable the radio to
communicate only with the other users set on the same frequency and on
the same CTCSS/DCS tone. HP108/408 has 50 CTCSS tones and 107 DCS
codes available (I/N Inverted – Normal).
You can choose amongst 7 different settings:
1. OFF: No CTCSS/DCS tone in tx and rx.
2. TONE: CTCSS tone set on the tx frequency only.
3. CTCSS : CTCSS tone set on both tx and rx frequency.
4. D CODE : DCS code set on the tx frequency only.
5. DCS: DCS code set on both tx and rx frequency.
6. T DCS: CTCSS set on the tx frequency and DCS code set on the rx
frequency.
7. D TSQL: Reception on the CTCSS tone and transmission on the DCS code.
CT or DCS icons on the display indicate the activation that you have set.
