to insure an adequate charge in the protection circuit, and to prevent any possible loss of memory during or
after installation, it is recommended that each unit be allowed to recharge for a period of 24 to 48 hours prior
to and during use by the customer.
In order to charge the batteries, the machine must be plugged in and its power switch must be set to the
"ON" position. This recharging precaution can prevent unnecessary equipment malfunctions or service calls.
