System Checks
Prior to troubleshooting the Cougar Digital Video Routing Switcher the
following basic system checks should be performed.
1. Verify the AC circuit condition. Ensure the unit is receiving the correct
voltage from the main AC power source.
2. Check all line fuses and power cords.
3. Ensure that all circuit cards are firmly seated
4. Ensure all interconnecting cables and connectors are plugged in or
firmly seated.
5. If applicable, ensure main power switch is turned on.
Replacement Parts
Only parts of the highest quality have been used in the design and
manufacture of the Cougar Digital Video Routing Switcher and its
associated circuit cards. If the inherent stability and reliability are to be
maintained, replacement parts must be of the same quality. A
replacement parts list is provided in Section 7 of this manual. When
replacing parts, avoid using excessive solder on the printed circuit board.
Always make sure that the solder does not short two circuits together. Be
sure the replacement part is identical to the original, and is placed in
exactly the same position with the same lead lengths (if applicable).
5.7 Filter Cleaning
The front door of the Cougar Digital Video Routing Switcher contains an
air filter. The air filter should be cleaned on a periodic basis. Remove the
filter from the door and clean it with soapy water or low pressure air. After
drying reinstall the filter in the door.
