ROUTINE MAINTENANCE

The bulleted items below describe routine maintenance that should be performed on a periodic basis.

•Clean the AV1 exterior surface with a soft, lint-free cloth. Do not use alcohol, benzene, acetone-based cleaners, or strong commercial cleaners. Do not use a cloth made with steel wool or metal polish. If the AV1 is exposed to a dusty environment, a low-pressure blower can be used to remove dust from its exterior surface.

•Replace the remote control batteries as needed. The remote control requires two AA batteries. When these batteries are low on power, the remote control enters a low-voltage condition that prevents it from operating the AV1. When this occurs, fol- low the instructions on page 1-5to replace the batteries. Nor- mal operation will resume when new batteries are installed.
