55 Replacing Consumables
This section explains how to replace the remote control batteries, the
lamp, and the air filter.
Replacing the Remote Control Batteries
If delays in the responsiveness of the remote control occur or if it does not
operate after it has been used for some time, it probably means that the
batteries are becoming flat. When this happens, replace them with new
batteries. Have two spare AAA-size alkali batteries ready to use when
required.
A
Remove the battery cover.
While pushing the battery compartment cover catch, lift the cover
up.
B
Replace the old batteries with new batteries.
Attention
Check the positions of the (+) and (-) marks inside the battery
holder to ensure the batteries are inserted the correct way.
C
Replace the battery cover.
Press the battery compartment cover until it clicks into place.
Attention
Make sure you read the Safety Instructions/World-Wide Warranty
Terms before handling the batteries. s
