PRECAUTION
This POS terminal 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 and its power switch must be set to the
“ON” position. This recharging precaution can prevent unnecessary initial service calls.
