Unless you are familiar with the use of repeaters, and are aware of repeaters near your location, we recommend you do not use semi-duplex operation; use only simplex operation, the default frequency bank of this transceiver. There are two separate "banks" of frequencies stored in the transceiver (as listed on pages 41 and 42). Frequency Bank A stores those frequencies used for simplex operation and Frequency Bank B stores those frequencies used for semi-duplex operation. To switch the bank between simplex (A) and semi-duplex (B) frequencies: 1 Turn the transceiver power OFF. 2 Press and hold the MENU key while turning the transceiver power ON (for 1 second). 3 Press the v or w key to select " ". 4 Press the MENU key to select " " (frequency bank A: simplex operation) or " " (frequency bank B: semi-duplex operation). 5 Press the PTT, MON, or CAL key to exit Setting Mode. 33
