Trouble Shooting
• There is very little that can go wrong with the XTD except a failure of
the fuse. Any other instance such as activation of the backup power
system may require servicing the unit by USL or trained technician.
• There are no user serviceable parts inside the unit.
• Updating the XTD firmware requires special knowledge and training
provided with the update package, please contact USL. Please make
note of the firmware version number on the rear of the unit.
Fuse replacement - Remove the power cord and pull out the fuse holder.
Replace the fuse with the same type and rating. Reinstall the fuse holder
making sure it is correctly oriented.
