Restart Button
The LCD display may fail to function normally
due to the vehicle's battery condition, and could
require restarting the radio's microprocessor if:
• The vehicle has been "jump started" from a
dead battery condition.
• The vehicle battery becomes very low and is
quick-charged.
• The vehicle battery is removed and replaced.
Should any of these conditions occur, simply
press and release the restart button on the radio
front panel using the tip of a ball point pen. This
will restart the radio's microprocessor. After
pressing the restart button, you should recheck
to see if the radio functions normally.
Replaceable Fuse
If the fuse should blow, check that the wiring is
correct. If the wiring is correct, replace the fuse
with the same amperage rating as the original
(15 amp).
