MAINTENANCE
REPLACING THE BATTERY AND FUSE

misuse.
• If the symbol
is shown on the product display this
means the battery is discharged and must be replaced.
• To replace the battery and fuse (500 mA 500 V fast for mA
connection, 5 A 500 V fast for 5 A connection), remove the
two screws underneath the product and replace the battery
or fuse. Insert the new battery with the correct polarity.
