Sharp ER-A280F - Manual (Page 3)

INTRODUCTION
Thank you very much for your purchase of the SHARP Electronic Cash Register Model ER-A280F/A280N.
Please read this manual carefully before operating your machine in order to gain full understanding of
functions and features. Please keep this manual for future reference. It will help you if you encounter any
operational problems.
IMPORTANT
• Install your register in a location that is not subject to direct sunlight, unusual temperature
changes, high humidity or exposure to water sources and keep away from heat and magnetic
sources.
Installation in such locations could cause damage to the cabinet and the electrical components.
• The register should not be operated by an individual with wet hands.
The water could seep into the interior of the register and cause component failure.
• Do not apply excessive pressure to the display.
Do not use a sharp-pointed object on the display.
The LCD display will be damaged easily.
• When cleaning your register, use a dry, soft cloth. Never use solvents, such as benzene and/or
thinner.
The use of such chemicals will lead to discoloration or deterioration of the cabinet.
• The surface of the screen may become smeared and accumulate dust during use.
Gently wipe the surface of the screen with a soft cloth that has been dipped in a mild detergent solution
and squeezed dry.
• The register plugs into any standard wall outlet (official (nominal) voltage).
Other electrical devices on the same electrical circuit could cause the register to malfunction.
• If the register malfunctions, call your authorized SHARP dealer for service - do not try to repair the
register yourself.
• For a complete electrical disconnection, the AC power cord must be removed from the wall outlet.
PRECAUTION
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 indicates that the service
life of the battery pack has expired.
If this is the case, consult your authorized SHARP dealer.
