Troubleshooting
D
Transmit and receive (Continued)
PROBLEM
The antenna is not prop-
erly tuned.
The supply voltage de-
creases when transmit-
ting.
The continuous transmis-
sions is inhibited.
Transmitting is impossible
in AM.
No voice synthesizer au-
dio from the speaker.
Cloning error occurs when
reading or writing through
the USB cable.
D Display
PROBLEM
The displayed frequency
does not change.
D Scanning
PROBLEM
A Programmed scan does
not start.
A Memory scan does not
start.
A Select memory scan
does not start.
A Mode select memory
scan does not start.
POSSIBLE CAUSE
• The antenna SWR is adjusted too high.
• Check the coaxial cable.
• The capacity of power supply is too low.
• The time-out timer activates.
• The 144/430 MHz frequency band is se-
lected.
• The speech level is set to minimum.
• The CI-V data transfer speed is set to 300
or 1200 bps.
• The CI-V data transfer speed is set to
Auto, but cloning is performed with 300 or
1200 bps.
POSSIBLE CAUSE
• The dial lock function is turned ON.
POSSIBLE CAUSE
• The same frequencies have been pro-
grammed into both "1A–3A" and "1B–3B"
of the scan edge memory channels.
• 2 or more memory channels have not
been programmed.
• 2 or more memory channels have not
been designated as select channels.
• 2 or more memory channels with the de-
sired mode have not been programmed.
SOLUTION
• Adjust the antenna SWR.
• Change the length of the coaxial cable.
• Use a power supply with capacity of at
least 22 Amperes.
• Turn OFF the time-out timer function.
• Select the HF/50 MHz frequency band.
• Adjust the speech level.
• Set the CI-V data transfer speed to other
than 300 and 1200 bps.
• Select the Clone mode in the Others Set
mode.
SOLUTION
• Hold down
SPEECH
OFF the function.
SOLUTION
• Program different frequencies into the
"1A–3A" and "1B–3B" scan edge memory
channels.
• Program more than 2 memory channels. Sec. 11
• Designate more than 2 memory channels
as select channels for the scan.
• Program more than 2 memory channels
with the desired operating mode.
