OPERATING BASICS

SWITCHING POWER ON/OFF

Switch ON the DC power supply, then press and hold down [POWER] until “HELLO” appears on the display. Release [POWER] when you see “HELLO”.

ATT PRE-AMP

•After the “HELLO” message, the frequency and other indicators appear.

To switch OFF the transceiver, press [POWER].

•After the transceiver has been switched ON, it can then be switched OFF or ON by using only the power switch on the DC power supply.

ADJUSTING VOLUME

AUDIO FREQUENCY (AF) GAIN

Turn the AF control clockwise to increase the audio level and counterclockwise to decrease the level.

Note: The position of the AF control does not affect the volume of “beeps” caused by pressing buttons nor the CW transmit sidetone. Also, the audio level for Packet operation is independent of the AF control setting.

RADIO FREQUENCY (RF) GAIN

Usually, set the RF control fully clockwise. If you are having trouble hearing the desired signal due to excessive atmospheric noise or interference from other stations, it may help to reduce the RF gain.

To do this, take note of the peak S-meter reading of the desired signal. Turn the RF control counterclockwise until the S-meter reads the peak value that you noted. Signals that are weaker than this level will be attenuated. Reception of the station will be easier.

Depending on the type and gain of your antenna, and the condition of the band, you may prefer leaving the RF control turned counterclockwise by some amount instead of turning it fully clockwise. When in FM mode, always set the RF gain control fully clockwise.

SELECTING VFO A OR VFO B

VFO A and VFO B are modes that allow any desired frequency to be selected within the frequency range of the transceiver. VFO A and VFO B function independently so that different or the same frequencies can be selected for each VFO.

Press [A/B] to toggle between VFO A and VFO B.

•“tA” or “tB” appears and shows which VFO is selected.
