Appendix B: Maintenance

This appendix describes some general care and service procedures for the MTM400 MPEG Transport Stream Monitor and includes the following subsections:

ƒPreventive Maintenance provides cleaning instructions.

ƒRack Mounting provides instructions for installing the unit in a 19-inch equipment rack.

Preventative Maintenance

Protect the unit from adverse weather conditions. The unit is not waterproof.

CAUTION. To avoid damage to the unit, do not expose it to sprays, liquids or solvents.

Do not use chemical cleaning agents; they may damage the instrument. Avoid chemicals that contain benzene, toluene, xylene, acetone or similar solvents.

Preventive maintenance mainly consists of periodic cleaning. The unit should be cleaned as needed based on the operating environment.

Cleaning the Exterior

Clean the exterior surfaces of the instrument with a dry, lint-free cloth or a soft- bristle brush. If dirt remains, use a cloth or swab dampened with a 75% isopropyl alcohol solution. A swab is useful for cleaning in narrow spaces around the connectors. Do not use abrasive compounds on any part of the unit.

CAUTION. Avoid getting moisture inside the unit during external cleaning. Use only enough cleaning solution to dampen the cloth or swab. Use a 75% isopropyl alcohol solution as a cleanser. To rinse, repeat the same process using a cloth dampened with de-ionized water.
