Detailed Description

•16 memory channels •Voice annunciation function •Super-save battery function •High capacity Li-ion battery Time-out Timer The purpose of the Time-out Timer is to prevent any single person from using a channel for an extended period of time. If you continuously transmit for 10 minutes,the transceiver will stop transmitting and a tone will sound.Top shop the tone,release the PTT swich. You can press the PTT switch again to resume transmitting. Battery Save The Battery Save function decreases the amount of operations are being performed (no keys are being pressed,and no switches are being turned). While the channel is not busy and no operation is performed for 10 seconds,Battery Save turns ON.When a signal is received or an operation is performed,Baterry Save turns OFF. Low Battery Warning Low Battery Qarning alerts you when the battery needs to be recharged. While transmitting,if the battery power goes below a per-dtermined value,the LED will blink red.When a toe sounds,the transceiver stops transmitting. Replace or recharge the battery pack. Monitor Qhen no signals are present,the squelch on the transceiver automatically mutes the speaker so you will ont hear background noise.Tomanually deactivate the squelch,press and hold the Monitor key.This is useful when you want to adjust the volume level,or when you need to hear a weak signal. The LED indicator lights green while the Monitor key is pressed. Quiet Talk(QT)and Dingital Quiet Talk(DQT) Some channeis may have pre-programmed QT/DQT tones,A QT/DQT tone is a subaudible tome which allows you to ignore (not hear)calls from other parties who are using the same channel. When you receive a signal that has a tone different from the one set up in your transceiver,you will not hear the signal.Linkewise,signals that you transmit will only be heard by parties whose QT/DQT tone matches the tone set up in your transceiver.
