5. Maintenance
The complete system should be tested at regular intervals. We suggest testing
it once every fortnight or at least once per month.
5.1. The Remote Control
The batteries in the remote control will need to be replaced
every 1 to 3 years, depending on usage. You are able to
recognise when the batteries are low from when the range
on the remote control reduces. The image at left shows the
deconstruction of the remote in order to replace the batteries
in the remote control.

5.2. The Detector
5.2.1. Replacing the batteries
The batteries can be removed by un-clipping them out
of the plastic battery holders. The new batteries must
be handled only by the edges as the chemicals in your
skin may cause a poor battery connection. Fingerprints
can be cleaned off the batteries with a soft cloth and
some alcohol solution. The new batteries can now be
slid into the battery holders making sure that the top
terminal is pressing down firmly on top of each battery.
Just after each battery is replaced the lights will begin
flashing 6 times to confirm the detector is now powered.
The 3 minute warm up period now applies.
