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
16
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
