TIME-OUT TIMER The purpose of the Time-out Timer is to prevent you from using a channel for a long time. This function is useful, for example, when you accidentally keep the PTT switch pressed. Additionally, by limiting the amount of time you can continuously transmit, this feature helps you save on battery power consumption. If you continuously transmit for 3 minutes (default value), the transceiver will stop transmitting and a tone will sound. To stop the tone, release the PTT switch. You can press the PTT switch again to resume transmitting. This transceiver is also equipped with a pre-alert tone which sounds 10 seconds before the Time-out Timer expires. This will allow you time to finish your message before the transceiver automatically stops transmitting. To change the default value of 3 minutes: 1 Turn the transceiver power OFF. 2 Press and hold the MENU key while turning the transceiver power ON (for 1 second). 24
