REVERSE FUNCTION The reverse function exchanges a separate reception and transmission frequency. So, while using a repeater, you can manually check the strength of a signal that you receive directly from the other station. If the station's signal is strong, both stations should move to a simplex frequency and free up the repeater. Note: ◆ You can turn the Reverse function ON when you are operating in Simplex Mode. However, it does not change the Transmission/ Reception frequencies. ◆ If pressing [REV] places the reception frequency outside the allowable range, an error tone sounds and the function does not operate. ◆ If pressing [REV] places the transmission frequency outside the allowable range, pressing Mic [PTT] causes an error tone to sound and transmission is inhibited. ◆ You cannot switch Reverse ON or OFF while transmitting. 144.725 MHz 145.325 MHz 144.725 MHz 6 REV ON TX: 144.725 MHz TX: 144.725 MHz TX: 144.725 MHz TX: 145.325 MHz RX: 145.325 MHz RX: 145.325 MHz RX: 145.325 MHz RX: 144.725 MHz To swap the transmission and reception frequencies: Press [REV] to switch the Reverse function ON (or OFF). • "R" appears when the function is ON.
