CAUTION!

When installing the system for the first time, or if the unit has not been

operating for two to three months, the data stored in memory may

be lost due to self-discharge of the integrated rechargeable back-

up battery.

The FMD55 will signal data loss acoustically as follows:

Beep: Short - Short - Long - Long - Short

The acoustic alarm should now stop and the FMD55 is returned to

normal operating status.

After loss of power e.g. switching off, it is possible that the alarm

may sound. Switch off for 5 seconds, if still beeping, press <EXIT>.
