Bose Lifestyle 48 Troubleshooting Manual

Placing the Bass Module into TAP Mode

Place all four DIP switches to the down position before returning the unit to the customer

1. Place the bass module into TAP mode

1.1 Set all four DIP switches into the "up"

position. Apply power to the bass module using

the AC line switch and wait until the amber

LED blinks twice and the green LED blinks

briefly at least once (approximately 3 seconds

after power up). Then, within twenty seconds,

flip ALL four switches down, then flip switch #4

(closest to the RJ-45 connector) back up. The

unit will now communicate in TAP mode. The

amber and green LED will blink alternately

when no S/PDIF signal is applied. Note that

when TAP mode is activated in this manner,

the DSP will echo characters sent by the

terminal.

RJ-45 connector to the bass module.

2.2 Type the command ST S and hit "Enter".
