Troubleshooting & Maintenance

JBL

ROUTINE MAINTENANCE

The following routine maintenance should be performed on a periodic basis:

Clean the SDP-40 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-40 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. It is recommended to use Alkaline batteries, which last longer without leaking. Refer to page 1-5 for remote control battery installation instructions.

Note:

When the batteries are low on power, the remote control enters a low-voltage condition that prevents it from operating the SDP-40. Normal operation will resume when new batteries are installed.

RESTORING FACTORY-DEFAULT SETTINGS

When factory-default settings are restored, all parameters and user-defined values are restored to their factory-default settings. Before restoring factory-default settings, it is recommended to record user-defined settings.
