ROUTINE MAINTENANCE

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

Clean the SDP-40HD 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 SDP-40HD 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 SDP-40HD. Normal
operation will resume when new batteries are installed.
