1. Locate the communications port on the
right side of the mask. Unscrew the fasten-
ing nut from the plug counterclockwise and
remove. The plug is then easily taken out
from the inside of the mask.
2. Loosen the fastening nut on the micro-
phone/push-to-talk (PTT) module of the ear/
mic assembly counterclockwise so that there
is space between the fastening nut and the
base of the module.
3. Insert the microphone/push-to-
talk (PTT) module into the mask’s
right communications port. The
nickel microphone wires may need
to be bent slightly to install.
4. Continue inserting the micro-
phone/PTT module into the com-
munications port. The lip of the
mask should go over the base of the
module and rest between the base
and the fastening nut.
5. The fastening nut is then turned
clockwise until tight against the
mask. Make sure the cable align-
ment of the OTS Ear/Mic Assembly
is similar to the photo above.

6. Once the microphone is inside
the port, carefully position it within
1/4” of the right corner of the
diver’s lips. The ME-16R Hot-Mic®
is shown above; other microphones
are available (e.g.,the Super Mic®,
our patented* all-depth, noise-
cancelling microphone).
7. The left earphone cable travels
snug up the right side of the visor
and over the top by tucking the wire
into the groove between the mask
and visor.
9. The EP-2 earphone is direc-
tional. With the shiny side facing
toward the diver’s ear, insert the
earphone into the earphone holder
(on each side) past the snaps with
the cable positioned below the snap.
Secure the snap.
8. Insert the temple and chin mask
straps through the top and bot-
tom slots of each earphone holder,
respectively. The snaps face toward
the front of the mask with the OTS
logo on each earphone holder up-
right. Reassemble the mask straps.

the OTS Ear/Mic Assembly.
Note: Before donning the mask,
position the earphone holders as
far back as possible to allow for
tightening of the mask straps. Once
fitted, adjust the earphone holders
into position.
10. The earphone cable should exit
the holder below the snap and run
parallel with the mask straps.
