Functions and Settings
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. See
Glossary for definitions of CTCSS and CDCSS.
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 ali 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. Rádios that set with the same
CTCSS/CDCSS, or no CTCSS/CDCSS, can receive from
you.
Battery Save
This feature can be enabled by your dealer. 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.
Pressing any key or receiving a signal will restore the
radio to normal operation and exit from Battery Save.
See Glossary for the definition of Battery Save.
Power Adjust
A press of the programmed Power Adjust key switches
the transmit power levei between high and low power.
Time-out Timer (TOT)
Limits the amount of time the radio user can continuously
transmit on a channel. If the user holds down the PTT
longer than the preprogrammed limit, the radio automati-
cally stops transmitting, and generates a warning tone
until the PTT is released.
Your dealer may program the alert tone that sounds be-
fore the TOT timer nearly expires.
