1. Unit will not turn-on
Make sure spa power is turned on, then
check both harness fuses on side of unit
making sure they are the proper ratings:
Yellow memory B+ line (10A fuse).
When faced with a malfunction during
operation, push BND button (8) and Eject
button (13) at the same time to reset
software.
With spa power off, use a paperclip to
press the reset button located besides the USB Docking Station (10)
to do a hardware reset.
Note: It will be necessary to re-enter the radio preset memories and
other personal settings after performing a reset. After resetting player,
always ensure all functions are operation correctly.

This condition may occur when it’s cold. Wipe fogged CDs with a soft
cloth. Fogged optical components inside the unit will return to normal
operation after an hour in a heated environment.
