Introduction

This camera is factory tested and adjusted for operational use. Under normal circumstances, the internal potentiometers do not need to be adjusted.

If it is discovered that the camera is misaligned, the following procedures are given as a guide for competent service personnel, who have a thorough knowledge of the camera and have the use of calibrated equipment, to realign the camera.

If no improvement can be achieved or an adjustment is out of range, please contact your local supplier or the nearest Thomson Multimedia Broadcast Solutions Service Centre.

The camera head adjustment procedures are designed as separate units. Within a numbered procedure do not change the position of switches or jumpers unless instructed to do so in the procedure.

These adjustment procedures are for the Camera Head. The adjustments require the use of a Master Control Panel in combination with an Operational Control Panel if possible. The intercom adjustments are given for a four-wire system.
