5-4. IN CASE OF DIFFICULTYThe problems described in this table are failures caused ingeneral by improper operation or connection of the re-ceiver, not by defective components. Examine and checkaccording to the following table. If the problem persists,contact an authorized agent or service station.Symptom Probable cause Corrective actionIndicators do not light and no receivernoise is heard when the POWERswitch is turned on.1. Bad power cable or connections.2. Blown power supply fuse.3. The TIMERswitch is ON.1. Check cables and connections.2. Contact the dealer.3. Turn the TIMER switch OFF .Nothing is displayed or wrong digitsare displayed when the POWER switchis turned on.The microprocessor may malfunctionif the input voltage is too low.1. Use a step-up transformer to raisethe line voltage.Use a 1 2V to 1 6V battery.2. Turn on the POWER switch whiledepressing the A = B key, and thenrelease the A = B key.When you press the POWER switch,"1 5 MHz AM" is displayed ... or the re-ceive sensitivity is low.The backup battery is discharged. Turn the POWER switch off with thepower cable plugged into an AC outlet,to allow the backup battery to charge.No signal is received even when theantenna is connected or the receivingsensitivity is low.1. SQL control fully clockwise.2. SELECTIVITY switch is set to "N".3. The RF ATT switch is ON.4. A wrong antenna number has beenassigned.1. Turn the SQL control counterclock-wise.2. Ensure the SELECTIVITY switch isset to "AUTO".3. Set the RF ATT switch to zero posi-tion RF ATT switch to zero.4. Select the correct antenna.An antenna is connected, but no signalis received and the S-meter fully de-flects.RF control is too low, decreasing thehigh frequency circuit gain.Turn the RF gain control fully clock-wise.The S-meter deflects and stays at acertain position even with no signal.1. Low AC line voltage.2. RF gain control closed.1. Use a step-up transformer to raisethe line voltage.Use a 1 2V to 1 6V battery.2. Turn the RF gain control fully clock-wise.Signal is received, but no sound isheard.MODE key position is incorrect. Change the MODE key to the correctmode.SSB received signal is extremely highcut or low cut.IF SHIFT control is wrong adjusted. Set the control to the center (click po-sition).Frequency is not changed by pressingthe 1 MHz (UP/DOWN) key or turningthe TUNING knob.F. LOCK key is ON. Set F. LOCK key to OFF.Program scan fails. 1. No frequency is stored in channels8 and 9 of the displayed channelgroup.2. Both HF and VHF frequencies arestored in channels 8 and 9 of thedisplayed channel group.1. Store the frequencies.2. Store either HF or VHF frequencies,not both.Memory scan fails. 1. Nothing is stored in memory.2. Nothing is stored in the selectedmemory scan group.Store the frequency.Display goes out with VFO/M ON. When nothing is stored in the memorychannel, a channel is displayed andblanked with only the decimal pointdisplayed.The TIMER does not work. 1. The on time or off time is not set.2. The TIME SET switch is ON.1. Program the on time or off time.2. Turn the TIME SET switch OFF.28
