Taking care of your Atlas IT
Battery Replacement
The Atlas IT requires no special maintenance, although the battery should be
replaced every 12 months to prevent leak damage.
If this message is displayed, the battery
should be replaced as soon as possible to
prevent malfunction or leak damage.
The unit may continue to operate following a low battery warning,
performance however, may be adversely affected.
To replace the battery, unscrew the three screws to remove the rear panel.
Remove the old battery and insert a new one, taking care to observe the correct
polarity.
The battery should be replaced with a high quality battery identical to, or
equivalent to an Alkaline 23A, V23A, GP23A, MN21 12V (10mm diameter x
28mm length). Carefully replace the rear panel, do not over-tighten the screws.
