Replacing the batteries
The batteries can be removed by depressing the battery
retention clip by pushing it in the direction indicated by
the arrow in the image to the right. The new batteries
must be handled only by the edges as leaving
fingerprints can cause a poor battery connection over
time. Fingerprints can be cleaned off the batteries with
a soft cloth and some alcohol solution. The new
batteries can now be placed, bottom edge first, into the
battery holder and then pushed down till they clip into
place. 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
).
