Modifying Room Name Details
G When you want to change the room names, use a slotted screwdriver to remove the remote controller cover and pull out the room name sheet.
[Removing the remote controller cover]
Insert the head of a slotted screwdriver into one of the open slots and remove
the cover by gently rotating the screwdriver as shown in the diagram on the right.
[Removing and inserting the room name sheet]
Pull out the room name sheet sideways to the right by using onto the hole on the
right side of the room name sheet.
If the names are written in pencil, use an eraser to remove the old names and
write new names in pencil.
After writing the new room names, insert the room name sheet by following the
above procedure in the reverse order.
[Refitting the remote controller cover]
First hook the cover to the two upper claws and then fit it to the remote controller.
NOTE • When rotating the slotted screwdriver to remove the remote controller cover, rotate it in a gentle fashion taking care not to apply much force.
If too much force is applied, it could break the claw parts.
• When refitting the remote controller cover, press it down until it snaps securely shut. If the cover is not securely shut, it may fall off.
• When using the room name sheet for the first time, you need to remove the protective sheet from the front surface of the sheet.
