Very clear scan, I recommend it. Definitely a must have for any 3362 owner.
Alpine could have written a slightly more complete manual, though. It's already pretty huge, but the unit has so many functions, I feel some more explanation would have been better.
Yamaha's manual of their comparable YDSP-1 is a little better in my opinion.
Immediate response with excellent service - highly reccommended

Selecting a Patch
To try out the various effects of the B2.1u, we recommend that you simply play your instrument while switching patches.
Turn power on
Use a shielded cable with mono phone plug to connect the bass guitar to the [INPUT] jack of the B2.1u. When using the B2.1u with the AC adapter, plug the adapter into the outlet and plug the cable from the adapter into the [DC IN] jack on the B2.1u. Set the [POWER] switch on the rear panel of the B2.1u to ON. Turn the bass guitar amplifier on and adjust the volume to a suitable position.
Set the B2.1u to play mode
If the Module selector is set to a position other than "PLAY", set it to "PLAY".
The bank and patch that were selected when the power was last turned off will appear on the display.

HINT
Immediately after turning the B2.1u on, the unit will be in play mode, even if the Module selector is set to a position other than "PLAY".
Select a patch
To switch the patch, press one of the [W]/[Q] foot switches.
Pressing the [W] foot switch calls up the next lower patch, and pressing the [Q] foot switch calls up the next higher patch. Repeatedly pressing one foot switch cycles through patches in the order A0 � A9 ... d0 � d9 � 00 � 09 ... 30 � 39 � A0, or the reverse order.
