5.3.1. Replacing the batteries

The batteries can be removed by sliding them out from 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
warm up period now applies (see section 2.5.3).

When replacing the batteries you must take the following into consideration:
• You must replace both batteries at the same time. Don't just replace one of them.
• Be sure not to touch the pyro detector on the removal or replacement of the
batteries.
• Carry out a walk test to ensure the detector is operating correctly.
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. Below describes how to replace the batteries in the
remote control.
