Advanced Operations
The following functions are programmable by your dealer.
CTCSS/CDCSS
Set up talkgroups with unique CDCSS/CTCSS to prevent unwanted conversations on the
same frequency. If CTCSS/CDCSS is set on the current channel, CTCSS/CDCSS match
is required for the radio to unmute to an incoming signal. If CTCSS/CCSS is not set, the
radio can receive calls from all users operating on the same frequency. Your dealer may
set CTCSS/CDCSS for some channels.
This feature does not mean that your conversation will not be heard by others. Radios that
set with the same CTCSS/CDCSS, or no CTCSS/CDCSS, can receive from you.
Note: See Glossary for definitions of CTCSS and CDCSS.
Battery Save
The Battery Save feature is automatically activated once no activity on the channel and no
operation performed (no key press and no knob selection), for extended operation time.
Once the radio detects no activity on the channel and no operation performed (no key
press and no knob selection) during radio standby time, it shall automatically enter sleep
mode ten seconds later. Pressing any key or receiving a signal will restore the radio to
normal operation and exit from Battery Save.
Note: See Glossary for the definitions of Battery Save and Standby.
