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
TR300 allows you to simply press the programmed Battery Strength Indicator key to illuminate the Status Indicator, which gives different indications representing battery strength levels. To exit the indications, release the key. The Status Indicator gives the following indications to represent corresponding battery strength levels

Indicator flashes red while the radio is operating.

Less than 10%| No indication is given when the programmed key is pressed. While the radio is in standby mode, Status Indicator flashes red and a

low-pitched tone sounds at intervals of ten seconds. If PTT key is

 | pressed at the moment, the radio will give an alert indicating that

transmission is prohibited.
