Setting up

Connecting power supply

At first, make sure that the power switch of the projector is set to OFF position (marked "O").

1. Put the connector of the power cord into the AC inlet of the projector.

2. Firmlyoutlet. plug the power cord’s plug into the

AC inlet Power cord

WARNING ►Please use extra caution when connecting the power cord, as incorrect or faulty connections may result in fire and/or electrical shock.

Only use the power cord that came with the projector. If it is damaged, contact your dealer to newly get correct one.

Only plug the power cord into an outlet whose voltage is matched to the power cord. The power outlet should be close to the projector and easily accessible. Remove the power cord for complete separation.

Never modify the power cord.

Using the security bar and slot

A commercial anti-theft chain or wire up to 10 mm in diameter can be attached to the security bar on the projector.

Also this product has the security slot for the Kensington lock.

For details, see the manual of the security tool.
