In case of a malfunction
Check the following items before requesting a repair.
z
The transceiver does not turn ON.
• Is the battery depleted?
• Charge the battery pack after purchase, and when the transceiver has not been used for a long time.
• Is the battery pack properly attached?
Refer to “Installing the Battery Pack” and securely mount the battery pack.
• Is the external power supply properly connected?
When using an external power supply, connect the external power supply adapter with a cigarette
lighter plug (SDD-13) or an external power cable (E-DC-6) to DC input jack.
• Is the voltage of the battery pack or the SDD-13 correct?
Be sure that there is a charge left in the battery pack (do not completely discharge). Check that the
output voltage of the SDD-13 is approximately 12V.
z
There is no sound.
• Is the level of squelch (or S meter squelch) set too high?
Press the Monitor Switch and verify that white noise can be heard.
Adjust the level of squelch (or S meter squelch) when receiving a weak signal.
• Is the volume low?
Rotate the VOL knob clockwise to increase the 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 signal
containing the same tone frequency or DCS code set.
• Is the C4FM digital mode on?
When the AMS function is on, the sound is not output until the transceiver receives a signal
containing the Analog FM mode.
Also, when the DG-ID function is on and set the DG-ID number to except for “00”, the sound is not
output until the transceiver receives a signal correspond to the DG-ID number.
z
There is no transmission of radio waves.
• Are you pressing the
PTT
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
signal even if
PTT
is pressed. Wait until signal being received stops and then press
PTT
.
• Is the transmission frequency on a ham radio band?
Transmission cannot be performed on the AM Radio Broadcast Band, the Short-Wave Radio Band,
the FM Radio Broadcast Band, the Air Band, or the 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 an inadequate power supply where voltage drops during transmission will prevent
the FT5DR/DE from operating at full capability.
z
The keys or DIAL do not respond.
• Is the Key Lock or DIAL Lock on?
z
The battery pack cannot be charged, or the battery power depletes immediately
after charging.
• Is the battery pack being charged with a charger specified by Yaesu?
Charge the battery pack using the accessory battery charger (SAD-25) or the rapid charge cradle
(CD-41). When using an external power supply, use the external power supply adapter with a
cigarette lighter plug (SDD-13) or an external power cable (E-DC-6).
When charging with an external power supply, charge in the input voltage range of 10.5 to 16 VDC
with the EXT DC IN terminal.
• Is the battery pack in use exhausted?
• If the “Charging Error” appears on the LCD when charging, there is a chance the battery pack is
over discharged. If the error is repetitively displayed after charging the battery pack several times,
the battery pack may have reached its service life or be defective. Battery packs are consumables.
Please replace the battery pack with a new one immediately. Battery packs can be charged and
reused up to approximately 300 times.
