Maintenance Instructions; Battery Charger Specifications - Xenotronix MHTX7 Series User Manual

CHARGER WILL NOT SWITCH TO READY MODE – If, after 15 hours, the charger
has not yet switched to the ready mode, try to determine if there was a power interruption
or a loose connection, which may have reset the charger timer for another 14 hours.
CHARGING INDICATOR IS ON WITHOUT A BATTERY ATTACHED - This
indicates that the output cable or connector may be shorted. If the indicator remains off
with the output cable removed then you should replace the cable. Do not attempt to
charge a battery with a shorted output cable.
RATTLE - If you think you hear a rattle inside the charger it is probably only a loose
terminal strip screw. Once the output cable is attached and the screws are properly
tightened, the rattle should go away.

MAINTENANCE INSTRUCTIONS

CLEANING - Unplug the charger and disconnect the battery before attempting any
cleaning. If it becomes necessary to clean the enclosure, wipe the enclosure exterior with
a damp cloth. If necessary, use a mild detergent. Do not use an abrasive cleanser or spray
cleaners directly onto the charger. Do not immerse unit in water.
