BATTERY
The programmer is fitted with a non-rechargeable, long life battery, which will maintain the
programmed time settings for a minimum of ten months with the supply disconnected.
THIS SHOULD BE SUFFICIENT TO COVER POWER INTERRUPTIONS DURING THE LIFE OF THE UNIT.
During power interruptions the display will be blank, after 3 days the current time of day will be lost.
If the programmer is not to be used for a long period of time, the switch on the rear of the unit
should be returned to the BATTERY OFF position. These are both to prolong the battery life.
