EM-OTS-2 INSTALLATION INSTRUCTIONS
Refer to Figure 11 and proceed as follows:
1. Locate the communications port on the
right side of the mask. Using the OTS
Wrench, unscrew (counterclockwise) the
fastening nut from the plug and remove.
Remove the plug from inside and store for
possible future use (Figure 17 on page 18).
2. Loosen (counterclockwise) the captive
fastening nut on the microphone and
push-to-talk (PTT) module of the earphone
and microphone assembly. Allow
enough the base of the module to accept the lip of the mask.
3.
Insert the microphone and 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 microphone and PTT module into the
communications 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.
6. Once the microphone is inside the port, carefully position it within
1/4” of the right corner of the diver’s lips. The port accepts either
the ME150 Microphone, ME-16R Hot-Mic, or Super Mic.
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.
8. Insert the temple and jaw mask straps through the top and
bottom slots of each earphone holder, respectively. The snaps
face toward the front of the mask with the OTS logo on each
earphone holder upright. Reassemble the mask straps.
9. Insert the earphone into the earphone holder (on each side) past the
snaps with the cable positioned below the snap. Secure the snap.
10. The earphone cable should exit the holder below the
snap and run parallel with the mask straps.
Note: In most cases of weak or bad communication, OTS has found that
the microphone has been installed under the seal and toward the chin.
The microphone needs to be clear of the seal and in the correct position
for good, clear communications.
