Maintenance
1. Low Battery Warning
When the battery power is low, a battery icon will appear on the display panel. The battery
should be replaced as soon as possible. The battery serves as a backup power for only for the clock.
The program is stored in the memory of controller (up to 20 years!) without any source power.
Note! If power fails when battery is low the clock must be reset. When electrical power is returned,
the clock will blink on and off and the programs will operate. The clock blinks to warn the operator
that there was a power failure (i.e. state of no electricity and no battery backup), making a
replacement of the battery and resetting of the clock necessary.
* The battery should last for at least one year (alkaline battery).
