Replacing the Backup Battery Pack

The memory backup battery pack has an expected life of approximately three years under normal conditions

(temperature extremes can shorten the life of the battery). Replace the memory backup battery pack every three years.

The battery pack is not available on the market, so please contact your dealer and ask him or her for replacement when you need a new one. Be sure to use a battery pack specified by SHARP.

Use of other battery packs could damage your POS terminal.

Caution : When you replace the battery pack, keep the POS terminal turned on. If you replace the battery pack with the power switch off, all the data in memory will be lost.

1.

Remove the screw in front of the battery compartment cover located at the bottom of the terminal and slide the cover in the direction of the arrow to detach it.
