MAINTENANCE
Cleaning
DO NOT use harsh solvents such as
benzine or alcohol when cleaning,
because they will damage the
transceiver surfaces.
If the transceiver becomes dusty or dirty,
wipe it clean with a dry, soft cloth.
Replacing fuse
A fuse is installed in each fuse holder of the supplied
DC power cable, to protect the transceiver.
If the transceiver does not turn ON because a fuse
blows, find and repair the cause of the problem. Then
replace any blown fuse with a new, adequately rated
fuse. (FGBO)
L Spare fuses are supplied with the transceiver.
R WARNING!
• Disconnect the DC power cable from the external power
source before replacing the fuse.
• NEVER use fuses other than specified ones.
Fuse Coding explanation
Fuse Coding: FUSE 250 V 8 A
Fuse Voltage Rating: 250 Volts
Fuse Current Rating: 8 Amperes
Resetting
Occasionally, erroneous information may be
displayed. This may be caused by static electricity or
by other factors.
If this problem occurs, turn OFF the transceiver.
After waiting a few seconds, turn ON the transceiver
again.
If the problem still exists, perform a Partial reset, as
described to the right.
If the problem still exists after a Partial reset, perform
an All reset, also described to the right.
NOTE: An All reset clears all data and returns all
settings to their factory defaults. Save memory
channel content, setting status, and so on, onto an
SD card before an All reset. (p. 6-2)
After performing a Partial reset
A Partial reset resets operating settings to their default
values (VFO frequency, VFO settings, menu contents)
without clearing the items listed below:
• Memory channel contents
• Keyer memory contents
• RTTY memory contents
• Call sign memories
• Message contents
• DTMF memory contents
• GPS memory contents
• Repeater list contents
• Network settings
• REF Adjust
• User Band Edges
• Fixed Edges
• Allowed call sign list contents
• Preset memory content
After performing an All reset
An All reset clears all data and returns all settings to
their factory defaults. Memory channel contents, filter
settings, and so on will all be cleared, so you will need
to rewrite your operating settings unless you have a
backup.
