SETUP AND INSTALLATION
Remote setup
Installing / replacing the batteries
Two AAA size batteries are supplied for the remote control.
1. Remove the battery cover on the back of the remote control.
2. Insert AAA batteries in the battery compartment as illustrated.
3. Replace back cover on remote control.
Notee:
Replace only with the same or equivalent type batteries.
CAUTION
Improper use of batteries can result in chemical leakage or explosion. Be sure to follow the instructions below.
‡ Do not mix batteries of different types. Different types of batteries have different characteristics.
‡ Do not mix old and new batteries. Mixing old and new batteries can shorten the life of new batteries or
cause chemical leakage in old batteries.
‡ Remove batteries as soon as they are depleted. Chemicals that leak from batteries that come in
contact with skin can cause a rash. If you find any chemical leakage, wipe thoroughly with a cloth.
‡ The batteries supplied with this product may have a shorter life expectancy due to storage conditions.
‡ If you will not be using the remote control for an extended period of time, remove the batteries.
‡ When you dispose of the batteries, you must obey the law in the relative area or country.
Effective range
Infra-Red (IR) remote control sensor is located on the top side and on the front side of the projector. Ensure to hold
the remote control at an angle within 30 degrees perpendicular to the projector's front IR remote control sensor
and 20 degrees perpendicular to the projector's top IR remote control sensor to function correctly. The distance
between the remote control and the sensor should not be longer than 7 meters (~ 23 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 closed 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 10 m 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.
