5.  MAINTENANCE, TROUBLESHOOTING

The 2A fuse inside the unit protects it from overcurrent and equipment fault. If the power cannot 
be turned on, have a qualified technician check the fuse. If the fuse has blown, find out the cause 
before replacing it. If it blows again, contact your dealer for advice.

This section provides simple troubleshooting procedures which the user can follow to restore nor-
mal operation. If normal operation cannot be restored, do not attempt to check inside the equip-
ment. There are no user-serviceable parts inside.
