Periodic Inspection
The SB4000 Boombox should be inspected periodically for external damage. At least once every 30 days of
use, perform the following checks:
1. Inspect the 16-pin Orbiter SR4000 Receiver connector for loose, bent or broken pins, misalignment, etc. Make
sure the RF Connector (Antenna) is intact and exhibits no apparent damage.
2. Check the VOL control for freedom of motion without binding of any kind.
3. Check that the Mode Selector push-button operates correctly in that it toggles between the Satellite Radio output
and the AUX input.
4. Make sure the antenna connector at the rear of the unit is free from damage of any kind and that the antenna
lead plug mates correctly and securely.
5. Make sure the DC 12V input connector at the rear of the unit is also free from damage of any kind and that the
AC Power Adapter plug mates correctly and securely.
6. Check the antenna for any physical damage; make sure the antenna cable is secure and not nicked or cut.
7. Inspect the overall Boombox case and speaker grilles for damage such as nicks, scratches, punctures, etc.
Cleaning the SB4000 Boombox
When cleaning the Boombox, make sure the AC Power Adapter is unplugged from the power source. Do not
use liquid cleaners or aerosol cleaners. Use a lint-free cloth lightly dampened with water for cleaning the
exterior of the Boombox only.
