Control Panel Installation
To prevent moisture and dirt from getting into the 1503C, special seals are used
around the LCD faceplate, options port, front panel, and front-panel button boot.
Removing the front-panel button boot or other rubber seals will require special
resealing procedures to retain the instrument weathertightness.
A list of sealants is provided on the next page to aid in reinstallation. However, we
recommend that resealing be done only by an authorized Tektronix Service Center.
The front panel/cover seal should be inspected regularly and replaced every six to
eight months, depending on the operating environment and use.
