You can operate multiple projectors simultaneously or individually with a single remote by assigning a unique ID number to each projector. The factory default ID is set to [ALL].

To set a unique ID:

2. On the remote control, press the button.

3. Within five seconds, press the number button (<1> – <6>) on the remote that corresponds to the projector’s ID.

To control all projectors at once, press the button on the remote control. This will control all projectors regardless of their assigned ID number.

To prevent loss, attach the lens cap using the supplied string:

1. Thread the thinner end of the string through the hole on the lens cap.

2. Thread the other end of the string through the hole on the bottom of the projector.

Attach the lens cap when moving the projector or when not using it for an extended period.

The Panasonic PT-VX420 has four installation modes, which can be set in the [PROJECTOR SETUP] menu under [PROJECTION METHOD].
