This register has a built-in memory protection circuit which is operated by a rechargeable battery pack. It
should be known that all batteries will, in time, dissipate their charge even if not used. Therefore to insure an
adequate initial charge in the protection circuit and to prevent any possible loss of memory upon installation,
it is recommended that each unit be allowed to be recharged for a period of 24 to 48 hours prior to use by the
customer.
In order to charge the battery pack, the machine must be plugged in. This recharging precaution can prevent
unnecessary initial service calls.
The battery pack is a consumable part, and its operating time will get shorter gradually each time it is recharged
for memory backup.
When the battery pack cannot be charged enough to perform memory backup, it means that the service life of
the battery pack has expired.
If this is the case, consult your authorized SHARP dealer.

Caution Scanner connection
In order to allow a plug & play connection of the optional scanner the Pin 9 of the D-Sub
connector 1 (Channel 1) uses +5V.
Be very careful of this +5V in case connection of a different device should be done so that a
damage of the register or device is avoided.
