CAN

 

The Scan key starts and stops the Scan mode on a channel that has been associated with a 
scan list and enabled for scanning.  Scanning will be indicated to the user with a rotating 
arrow icon. 

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 2

nd

 press of the scan button will turn scanning off.  

Note that if Autoscan is programmed for that channel, the Scan key will not function.

This key is used to enter the Scan Edit menu, where the members of a scan group can be 
added or deleted.

NALOGUE

This function enables transmitted voice to be scrambled, 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. 

Scrambler On/Off state is reset to Off at power-up and channel change. 

CTCSS operates as normal. 

First press of the function button enables scrambler mode. 

The 2

nd

 press restores channel to normal (clear) mode. 

6.15 S

KIP

 

The Skip function key is used to temporarily remove members from a scan channel.   The 
removal is temporary only until the channel is changed. 

6.16 S

QUELCH

 

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 talkgroup and individual 
calls. 

6.17 T

ALKAROUND

 

This function will change the Transmit and Receive frequencies (and CTCSS tones) so that a 
local Repeater can be bypassed. 

It is supported in both analogue and digital mode. 

The first button press will redefine the channel’s Rx\TX frequencies as specified by the FPP 
Talk-Around field: 

• 

Swap Transmit and Receive frequencies 

• 

Make Transmit Frequency same as Receive Frequency.
