the power supply cord from the outlet and contact your dealer or the JRC Customer Service
Department.
See the back page of the warranty for regulations on warranty coverage.
10.2 Troubleshooting
Before you jump to the conclusion that the machine has a problem, check the following items.
Symptom
No power-up
@
The antenna switch
cannot be operated
independently.
@
The POWER cannot
be turned on from
the front panel.
The cannot be
turned on.
The automatic tuning
operation and
I
or the
SET operation cannot
be implemented.
Low output power
The frequency does not
change correctly dur-
ing the SET operation.
The automatic tuning
operation is aborted
while in progress.
When entering the
operating state upon
start-up, there is
nothing displayed on
the central indicator.
Cause
The 13.8 V power from the exciter
is not supplied or the POWER
SUPPLY CONT. switch on the rear
panel is set to EXTERNAL.
The exciter is in the transmission
mode.
@
Automatic tuning has not been
achieved (the frequency
display is off or blinking).
@
The exciter frequency is not
within the hamfrequency
band.
@
The frequency is in the 28
MHz frequency band.
@
The exciter is in the
transmission mode.
@
Insufficient output power from
the exciter
@
The control cable is
disconnected.
@
The coaxial cable is not
connected correctly, or the
cable has poor contact.
@
The ALC level setting is not
correct.
@
The output power from the
exciter is insufficient.
@
An alarm is in effect.
@
The is off.
The exciter is in the split mode.
@ I
The output power from the
exciter is insufficient.
@
Relay is not switched in the
transmission mode.
The battery that backs up the
RAM has been discharged.
Cure
Check the connections or set the POWER
SUPPLY CONT. switch on the rear panel to
ON.
Turn the POWER on after setting the exciter
in the reception mode.
Implement the automatic tuning operation.
Or switch to the antenna in which the
automatic tuning operation has been
successfully achieved.
Reset the exciter frequency within the Ham
frequency band.
The cannot be turned on in the 28 MHz
frequency band.
Turn the on after setting the exciter to
reception mode.
lncrease the output power from the exciter.
Connect the control cable securely.
Make correct connection.
Readjust the ALC level.
Increase the output power from the exciter.
Turn the POWER on again after turning the
JRL-2000F off.
Turn the on.
During the SET operation, the exciter
transmission frequency is counted.
Increase the output power from the exciter.
In the automatic tuning operation, the
frequency is counted first, and then tuning
is implemented. When the operation shifts
from frequency counting to tuning, set the
exciter to the reception mode first.
Charge the battery for a minimum of three
hours.
