Scan is supported in both analogue and digital mode.
If scan is enabled for the current channel in the current zone and auto scan is not
enabled, then start scanning the channels defined in the current channel’s scan group.
The second press of the scan key will turn scanning off.
Note:- If Auto-scan is programmed for that channel, the Scan key will not function.
7.13. SCAN EDIT
This key is used to enter the Scan Edit menu, where the members of a scan group can
be added or deleted.
7.14. SCRAMBLER (P25 ANALOGUE)
This function enables transmitted voice to be scrambled in order to prevent radios
without a scrambler from listening in on the conversation.
This low security form of encryption is sufficient to make speech unintelligible to other
casual listeners, however it does not offer high level security as other radios
programmed with a scrambler function will be able to unscramble it.
Supported in analogue mode only.
The speaker sounds a “bip-bip” tone when PTT is pressed to indicate that scrambler is
active.
The Scrambler On/Off state is reset to Off at power-up and channel change.
A first press of the function key enables scrambler mode.
A second press restores the channel to normal (clear) mode.
7.15. SKIP
The Skip function key is used to temporarily remove members from a scan channel.
The removal is temporary only until the channel is changed.
7.16. SQUELCH (P25 CONVENTIONAL)
The squelch mode is used to selectively receive P25 signals. It has three modes,
Monitor, Normal and Selective. When set to Monitor, all P25 traffic on that channel will
be heard, subject to presence of encryption. Normal mode will hear all P25 traffic with
the correct NAC code. Selective mode will only receive calls to the channel default talk
group and individual calls.
