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 has been 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 with the same CTCSS/CDCSS or with no CTCSS/CDCSS, can receive
calls from you.
Battery Save
The Battery Save feature will be automatically activated once no activity is
present on the channel and no operation is 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 will
automatically enter sleep mode ten seconds later. Pressing any key or
receiving a signal will cause the radio to exit from Battery Save and restore it
to normal operation.
Power Adjust
Users can switch the Tx power level between high and low power by pressing
the programmed
Power Adjust key.
Time-out Timer (TOT)
The TOT timer limits the amount of time the radio can continuously
transmit on a channel. This can also protect your radio from damage due to
excessive transmission. If the user holds down the
PTT key longer than the
preprogrammed time period, the radio will automatically stop transmitting and
generate a warning tone. To stop the warning tone, release the
PTT key.
Your dealer may program the alert tone that sounds before the TOT timer
nearly expires.
Battery Strength Indicator
TC-320 allows you to simply press the programmed Battery Strength
