System Checks
Prior to troubleshooting the Cougar 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 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).
The front door of the Cougar 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.
