When the battery is nearly discharged, the ALARM indicator will blink, bit
A42615 will turn ON, and the message "BATT LOW" will appear on the Program-
ming Device. When this occurs, replace the battery within one week to avoid loss
of data. The battery and connector are provided as a set. To replace the Battery
Set, follow the steps below. The entire replacement must be completed within
five minutes to ensure that the data will not be lost.
Do not short circuit, charge, disassemble, or expose the battery to heat. The bat-
tery fluid is flammable and if mishandled, may cause a fire or explosion. Do not
incinerate the battery after use.
The expected life of the battery is 5 years for any CPU. The memory backup
times are given in the following table.
