Maintenance:
Unit should be tested at least once a year for the proper
operation as follows:
Output Voltage Test: Under normal load conditions, the DC
output voltage should be checked for proper voltage
level (Power Supply Output Specifications Chart).
Battery Test: Under normal load conditions check that the
battery is fully charged, check specified voltage both at
battery terminal and at the board terminals marked [+ BAT -- ]
to insure there is no break in the battery connection wires.

mended changing batteries in 4 years or less if needed.
