If your transceiver seems to be malfunctioning, please check the following points before sending it to a service center.
PROBLEM POSSIBLE CAUSE SOLUTION REF.
Transceiver does not turn
ON.
• The battery is exhausted.
• The battery polarity is reversed.
• Loose connection of a battery pack (case).
• Charge the battery pack, or replace the batteries.
• Check the battery polarity.
• Clean battery terminals.
pp. 2, 11–14
p. 11
–
No sound comes from the
speaker.
• Volume level is too low.
• An external speaker or a cloning cable is con-
nected to the [SP] jack.
• Rotate [VOL] to adjust to a desired level.
• Check the external speaker connection or remove
the cloning cable.
p. 16
–
Transmitting is impossible.
• A frequency outside of the 144/440 MHz ama-
teur bands is set.
• The PTT lock function is activated.
• The heat protection is activated, and “Hot” is
displayed.
• Set the frequency within 144/440 MHz amateur
bands.
• Set the PTT lock function OFF in the Initial set mode.
• Cool down the transceiver.
p. 20
p. 62
p. 23
Transmitting using the VOX
function is impossible.
• The VOX gain is set to OFF or too low.
• The microphone gain is too low.
•
Set the VOX gain to a suitable level.
•
Set the microphone gain to a suitable level.
p. 81
p. 58
Contacting with another
station is impossible.
• Different tone or code is used for the tone/
DTCS squelch.
• Check the tone/DTCS by performing a tone scan. p. 71
Frequency cannot be set. • The lock function is activated.
• The memory mode, Call channel mode, or
weather channel mode is selected.
• Push and hold [ ](SET) for 1 sec. to cancel the
lock function.
• Push [V/M/C] repeatedly to select the VFO mode.
p. 21
p. 18
A program scan does not
start.
• The memory mode, Call channel mode, or
weather channel mode is selected.
• The same frequency has been programmed in
the scan edge channels, “✱A” and “✱b.”
• Push [V/M/C] repeatedly to select the VFO mode.
• Programming different frequencies in the scan edge
channels.
p. 18
p. 43
A memory scan does not
start.
•
The VFO mode or Call channel mode is selected.
• Only one or no memory channel has been pro-
grammed.
•
Push [V/M/C] repeatedly to select the memory mode.
• Program 2 or more memory channels.
p. 18
p. 31
The displayed frequency is
erroneous.
• The CPU has malfunctioned.
• External factors have caused a fault.
• Reset the transceiver.
• Remove and re-attach the battery pack/case.
