or when there is an obstacle in the path.
•When remote control buttons are pressed and held, projector’s func-
tion keys may not operate.
•Do not subject to strong shock.
•Do not allow water or other liquid to splash on the remote control. If
the remote control gets wet, wipe it dry immediately.
•Avoid exposure to heat and steam.
•Remove the batteries from the remote control when the remote con-
