OPERATING BASICS SWITCHING POWER ON/ OFF 1 Switch the DC power supply(s) ON if you are using a DC power supply(s). 2 Press and hold [ ] (POWER) briefly to switch the transceiver ON.

When this warning message appears, you can receive signals as usual but you cannot transmit even if you decrease the output power. "TWIN PWR" appears when two DC power cables are connected to the DC-1 and DC-2 connectors. • Upon power up, "HELLO" appears on the main display, followed by the selected frequency and other indicators. 3 To switch the transceiver OFF, press [ ] (POWER) again. 4 Switch the DC power supply(s) OFF. • You may skip step 3. After switching the transceiver ON, you can switch it OFF or ON using only the power switch of the DC power supply(s). The transceiver remembers the information of the POWER switch position when the DC power source is switched OFF. ADJUSTING VOLUME AF (AUDIO FREQUENCY) GAIN Turn the AF control clockwise to increase the audio level and counterclockwise to decrease the level.

The audio level for Digital mode operation is also independent of the AF control setting. 18 RF (RADIO FREQUENCY) GAIN The RF gain is normally configured to the maximum level regardless of the operating modes. The transceiver has been configured to the maximum level at the factory. However, you may decrease the RF gain slightly when you have trouble hearing the desired signal because of excessive atmospheric noise or interference from other stations. First, take note of the peak S-meter reading of the desired signal. 1 Press [MIC/ RF.G] (1 s).

Depending on the type and gain of your antenna, and the condition of the band, adjust the RF gain. When using FM mode, always adjust the RF gain to the maximum level. SELECTING VFO A OR VFO B Two VFOs are available for controlling the frequency on the transceiver. Each VFO (VFO A and VFO B) works independently so that a different frequency and mode can be selected. For example, when SPLIT operation is activated, VFO A is used for reception and VFO B is used for transmission. The opposite combination is also possible. Press [A/B / M/V] to toggle between VFO A and B.
