Optoma BT16063, Operating Manual, Page: 7 / 9

CAUTION:
To ensure safe operation, please observe the following precautions:
. Use CR2032 type battery.
. Avoid contact with water or liquid.
. Do not expose the remote control to moisture or heat.
. Do not drop the remote control.
. If the battery has leaked in the remote control, carefully wipe the case clean and install new battery.
. Risk of an explosion if battery is replaced by an incorrect type.
. Dispose of used battery according to the instructions.
Effective range
Infra-Red (IR) remote control sensor is located on the rear of the projector. Ensure to hold the remote
control at an
angle within 30° (horizontally) or 20° (vertically) perpendicular to the projector’s IR remote control sensor
to function
correctly. The distance between the remote control and the sensor should not be longer than 7 meters
(~22 feet).
You can also operate the remote control by pointing it to the projected image.
Note: When pointing the remote control directly (0 degrees angle) on the IR sensor, the distance between
the remote control and the sensor should not be longer than 10 meters (~32 feet).
. Make sure that there are no obstacles between the remote control and the IR sensor on the projector
that might obstruct the infra-red beam.
. Make sure the IR transmitter of the remote control is not being shined by sunlight or fluorescent lamps
directly.
. Please keep the remote controller away from fluorescent lamps for over 2 meters or the remote
controller might become malfunction.
. If the remote control is close to Inverter-Type fluorescent lamps, it might become ineffective from time
to time.
. If the remote control and the projector are within a very short distance, the remote control might
become ineffective.
. When you aim at the screen, the effective distance is less than 7 meters from the remote control to the
screen and reflecting the IR beams back to the projector. However, the effective range might change
according to screens.
