Remote control effective range
El sensor de infrarrojos del mando a distancia está
situado en la parte frontal y superior del proyector.
The remote control must be held at an angle
within 30 degrees perpendicular to the projector's
IR remote control sensor to function correctly. The
distance between the remote control and the
sensor should not exceed 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.
