- To ensure the most secure installation, please use a ViewSonic® wall or ceiling mount.
- Ensure the screws used to attach the mount to the projector meet the following specifications:
CAUTION
- Avoid installing the projector near a heat source or air conditioner.
- Keep at least a 10 cm (3.9 in.) gap between the ceiling and the bottom of the projector.
Using the Security Bar
To help prevent the projector from being stolen, use a security slot locking device to secure the projector to a fixed object. The security slot can also be used as a safety anchor if the projector is mounted to the ceiling.
