MAINTENANCE 10 Troubleshooting (Continued) PROBLEM The transceiver automatically switches to transmit while receiving. POSSIBLE CAUSE The VOX function is ON. The VOX gain is set too high. SOLUTION Turn OFF the VOX function in the Multifunction menu. REF. p. 1-6 Adjust the VOX gain. p. 1-6 Cannot contact with another station, even if receiving and transmitting seem normal. The Split function is activated. (T he transmit and receive frequencies are different.) The RIT function or the ∂TX function is ON, and a different receive or transmit frequency is set. Push SPLIT to turn OFF the Split function. Push RIT or TX to turn OFF the function. p. 4-9 p. 4-1 - Received audio in the SSB mode is unclear or distorted. The incorrect sideband is selected. The PBT function is activated. Toggle between USB and LSB. p. 3-3 Rotate TWIN PBT CLR to clear the settings. p. 4-3 Transmit signal is unclear or distorted in the SSB mode. The transceiver's microphone gain is too Adjust the MIC GAIN level so that the high. meter reading swings between 30 and The desktop microphone gain is too high. 50% of the ALC scale. p. 3-9 The operating frequency The Dial Lock function is activated. is not properly changed by rotating MAIN DIAL . Hold down SPEECH to turn the Dial Lock function OFF. p. 3-6 Programmed scan does The same frequencies have been set in Set different frequencies in scan edge - not start. scan edge memory channels P1 and P2. memory channels P1 and P2. Memory scan does not start. Select memory scan does not start. No, or only 1 memory channel is set. No, or only 1 memory channel is designated as a Select channel.

Cannot hear the speech The speech level is too low. after pushing SPEECH . When you want to save the changed settings, touch [MW] for 1 second to write them into the memory channel on the VFO/MEMORY screen. Adjust "SPEECH Level" in the Speech setting. - p. 8-3 The antenna SWR is too The antenna is not properly tuned. high. Adjust the antenna SWR. p. 7-3 The antenna SWR should be less than 3. The coaxial cable is not suitable. Use a coaxial cable whose characteristic p. 12-1 impedance is 50 Ω. "OVF" is displayed. The touch screen is not working correctly. An excessively strong signal is received. Rotate AF RF/SQL (outer) counter clockwise. Turn ON the attenuator. p. 3-7 p. 4-1 Turn OFF the Preamplifier (P.AMP OFF). p. 4-1 Turn ON the Digital Selector function. p. 4-6 The touched point and the detected point Calibrate the touch screen in the may be different.
