Notes on batteries
• Make sure that the battery orientation is correct when
inserting batteries.
• Do not mix an old battery with a new one, or
different types of batteries.
• If you will not use the Remote Commander for a
long time, remove the batteries to avoid damage
from battery leakage. If batteries have leaked,
remove them, wipe the battery compartment dry and
replace the batteries with new ones.
Notes on Remote Commander operation
• Make sure that there is nothing to obstruct the
infrared beam between the Remote Commander and
the remote control detector on the projector.
• The operation range is limited. The shorter the
distance between the Remote Commander and the
projector is, the wider the angle within which the
commander can control the projector.
