the back cover cannot be removed easily.

• The battery mark fl ashes only when the battery has expired. The battery mark is not normally displayed.
• The initial batteries were used for operation checks when the remote control was installed, so their service life
may be shorter than commercially available batteries.
• Depending on the size of the room, fi nishing and color (particularly a dark color) of the wall, the remote control
may stop functioning before the battery indicator starts fl ashing.
