Unpacking
Unpack the SDD3 and check to see if there is
any damage to it. If you nd any damage notify
your supplier immediately. Only the consignee
may institute a claim with the carrier for any
damage incurred during shipping. Be sure to
save the carton and all packaging materials for
the carrier’s inspection.
Should you ever need to ship the unit, only use
the original factory packaging. If the shipping
carton is unavailable, contact your supplier to
obtain a replacement.
The SDD3 carton should contain:

Rack mounting
The SDD3 will mount in a standard 19” rack
system. Use four screws and washers to mount
the SDD3 to the rack rails. We recommend
using a shock-mounted rack for touring use to
prolong the life of your SDD3.
To prevent accidental adjustment of settings, or
unwanted tampering in a xed installation,
