• Do not drop the remote control or expose it to moisture or high temperature.

• The remote control may malfunction under a fluorescent lamp. If that occurs, move the 

DHD Controller away from the fluorescent lamp.

• Make sure that there is nothing obstructing the infrared beam between the remote 

control and the IR receiver on the DHD Controller or projector.

• If the effective range of the remote control decreases, or it stops working, replace the 

batteries with new ones.

• Ambient conditions may possibly impede the operation of the remote control. If this 

happens, point the remote control at the DHD Controller or projector and repeat the 
operation.
