INTRODUCTION
Thank you very much for your purchase of the SHARP Electronic Cash Register, Model ER-A410/A420.
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 electronic 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.
• When cleaning your register, use a dry, soft cloth. Never use solvents, such as benzine and/or thinner.
The use of such chemicals will lead to discoloration or deterioration of the cabinet.
• 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 local dealer for service - do not try to repair the register yourself.
• For a complete electrical disconnection, pull out the mains plug.
PRECAUTION
This Electronic Cash Register has a built-in memory protection circuit which is operated by rechargeable
batteries.
As you know, 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 recharge for a period of 24 to 48 hours prior to use by the customer.
In order to charge the batteries, the machine must be plugged in. This recharging precaution can prevent
unnecessary initial service calls.
