10 seconds. Then, set the rear panel power switch to the
I(“on”) position.
2. Use the SDP-40HD configuration tool to download the current
SDP-40HD configuration to a personal computer (PC) or
document all of your current settings on the installation
worksheet that begins on page A-19. Then, follow the
instructions on the next page to restore factory default settings.
If all else fails. . .

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.
