7.3.6 Synchronization Adjustments

Synchronization Adjustments

It is possible to adjust the synchronization in Computer mode by adjusting the Phase and the Frequency. The synchronization will be set by the automatic set-up function. Manual sync adjustments should typically not be required.

The setting will follow the source, which means that you can have different settings for video and computer. The pre-defined settings will also vary with the source.

8. Maintenance

All maintenance should be done by Zenith authorized ser- vice personnel. Contact your Zenith dealer for maintenance.

The Zenith projector lamp is designed to give you many hundreds of hours of operation. In the unlikely event that you should have to replace the lamp, you will find complete instruction on how to replace the lamp includ- ed in the spare lamp kit.
