Maintenance
Air Flow
When you insert the new battery, be careful to observe the correct polarity.
Air Flow
A fan in the EC9535 frame draws cooling air from the front of the frame, through the door, and
exhausts heated air through the rear. The EC9535 must have the door correctly installed and
closed for proper airflow through the chassis. For maximum air flow, regularly inspect the fan. If
the fan becomes dusty, gently vacuum the fan and grills.

Grass Valley
will assign you a Return Material Authorization
(RMA) number. Do not return equipment without first receiving an RMA number.
Grass
Valley

For out-of-warranty service,
Grass Valley
will send your company an invoice following the
repair or replacement.
To prevent explosion of the battery and possible equipment damage or harm to
personnel, be sure the battery is oriented with the correct polarity. Polarity
markings are visible on the card’s battery housing.
If airflow is impeded overheating may occur.
