Figure 25: Receive Module with cables connected
Prior to mounting the Receive Module, the block that holds the sound velocity probe must be
secured through the underside of the mounting bracket. Next, mount the Receive Module in the
mounting frame. This can be most easily done by putting the receive module face on a piece of
cardboard or other material and then lowing the mounting frame down with the threaded bolts
passing through the mounting frame. The threads, of the securing bolts, after passing through the
frame,
must be wrapped with 2 wraps of Teflon™ tape . This is to prevent galling where the nut will
freeze on the bolt.
Do not tighten beyond 17Newton metre
(150 pound-inch or 12.5 pound-foot).

(Wrap threads with Teflon tape, then secure with a flat washer, locking washer and then the nut.)
