Operating Range
The infrared signal operates by line-of-sight up to a distance of approximately 9.8 (3 m) and
within a 30-degree angle of the remote sensor. The projector will not function if there are
objects between the remote control and the remote sensor on the projector or if strong light
falls on the remote sensor. A weak battery will also prevent the projector from operating.
This sample may be slightly different from actual range.
Remote Control Precautions
Handle the remote control carefully.
Do not use the remote control if it got wet. Remove the battery immediately. Make sure
the remote control and battery are dry before use.
Avoid excessive heat and humidity.
Do not place the battery upside down.
Keep the coin cell battery out of reach of children so as not to allow them to swallow
the cell battery.
