NEC P627UL Wichtige Information Seite 18

• About handling of the remote control
- The remote control will not work if the projector's remote signal sensor or the remote control's
signal transmitter is exposed to strong light or if there are obstacles between them that obstruct
the signals.
- Operate the remote control from within 7 meters from the projector, pointing it at the projec-
tor's remote signal sensor.
- Do not drop the remote control or handle it improperly.
- Do not let water or other liquids get on the remote control. Should the remote control get wet,
wipe it off immediately.
- Avoid using in hot and humid places as far as possible.
- When planning not to use the remote control for long periods of time, remove both batteries.
• Take measures to prevent external light from shining on the screen.
Make sure only the light from the projector shines on the screen. The less external light on the
screen, the higher the contrast and the more beautiful the images.
• About screens
Images will not be clear if there is dirt, scratches, discoloration, etc. on your screen. Handle the
screen with care, protecting it from volatile substances, scratches and dirt.
Clearance for Installing the Projector
When installing the projector, keep sufficient space around it, as described below. If not, the hot
exhaust emitted from the projector may be taken back in.
Also, make sure no wind from an air-conditioner hits the projector.
The projector's heat control system may detect an abnormality (temperature error) and automati-
cally shut off the power.

about 10 cm or more space behind, and even more space for installing the cables.
