147AppendixIf you suspect malfunction Check the following items before requesting for repair.The transceiver does not turn on.Is the battery is depleted?Charge the battery pack after purchase, and when the transceiver has not been used for a long time.Is the battery pack properly set?Refer to “Mounting the battery pack” and securely mount the battery pack.Is the external power supply properly connected?When using a external power supply, connect an external power supply adapter with a cigarette lighterplug (E-DC-5B) or an external power cable (E-DC-6) to this jack.Is the voltage of the battery pack or the E-DC-5B correct?Be sure that there is a charge left in the battery pack (do not completely discharge). Check that theoutput voltage of the E-DC-5B is approximately 12V.There is no soundIs the level of squelch (or S meter squelch) set too high?Press the Monitor Switch and check that you can hear white noise.Adjust the level of squelch (or S meter squelch) when receiving a weak signal.Is the volume low?Turn O clockwise while pressing v to increase the sound volume.Is the tone squelch or DCS on?When the tone squelch or DCS is on, the sound is not output until the transceiver receives a signalcontaining the same tone frequency or DCS code set.There is no transmission of radio waves.Are you pressing the p switch properly?Is the PTT lock on?Is the Busy TX Block (BCLO function) on?When the Busy TX Block (BCLO Function) is on, transmission cannot be done when receiving a signaleven if p is pressed. Wait until signal being received stops and then press p.Is the transmission frequency on an ham radio band?Transmission cannot be performed on the AM Radio Broadcast Band/ Short Wave Radio Band/ FMRadio Broadcast Band/ Air Band/ Information Radio Band.Is the voltage of the battery pack or external power source correct?Check the remaining charge on the battery pack.In addition, using a power supply where voltage drops during transmission will prevent the FT1DR/DEfrom operating on full capability.The keys or O does not respond.Is the Key Lock or DIAL Lock on?
