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.
