Ocean Technology Systems EMDG-2SM User manual

1. Remove the plug from the left connection port (on the left
side of the mask from the diver’s perspective), by pressing
the colored release button on the side of the port and gently
pulling out the plug.
2. Remove from the oral-nasal pocket the one-way valve
beneath the now-open connection port. When unseating the
valve’s hard plastic housing from the pocket wall, be careful
to not pull on the valve’s soft rubber ap.
4. With the shorter earphone cable pointing toward the left
mask strap (see the illustration), insert the PTT/microphone
assembly into the open port, with the microphone element fac-
ing inward. Push the housing into the port completely, until the
locking mechanism snaps to hold it securely in place.
5. Insert the microphone housing into the opening of the oral-
nasal pocket.

3. Remove the microphone housing of the EMDG-2SM from
the push-to-talk (PTT) housing by pulling gently and steadily.
Be careful not to damage the wires connecting them.
6. Pull the wall surrounding the opening of the oral-nasal
pocket over and into the microphone housing groove. The edge
of the wall must be entirely inside the groove.

7. Ensure the microphone assembly rests loosely inside the PTT housing.
9. Remove both the upper and lower mask straps from the buckles on the left side of the mask.
8. Unsnap the EHA-1 earphone holders on the EMDG-2SM, and pull out the earphones.
11. Identify the left earphone, which has the shorter of the
two cables. Insert it behind the left mask handle (from which
you removed the mask straps in Step 9) and into the earphone
holder. The side of the earphone marked “this side away from
ear” must face outward, away from the mask. With the cable
below the snap, snap closed the earphone holder.
10. Install one of the EHA-1 earphone holders onto the mask
straps, as illustrated. It should be positioned on the straps such
that it will be directly over the diver’s left ear. Reinstall the
mask straps onto the buckles as before.
12. Repeat steps 9 and 10 for the right side of the mask. Then
pull the right (longer) earphone cable along the groove on the
bottom of the mask, as illustrated. Pull the earphone behind
the right mask handle, and insert it into the holder. (Again, the
side of the earphone marked “this side away from ear” must
face outward, away from the mask.) With the cable below the
snap, snap closed the earphone holder.
The installation is now complete, with any minor adjustments to be made once the diver has donned the mask and tests the
communications system.
NOTE: USING AN OHM METER TO TEST THE EAR/MIC ASSEMBLY WILL CAUSE IRREPARABLE
DAMAGE TO THE UNIT!
13. Use the two supplied cable ties to secure the earphone
cables to the mask strap buckles: the lower buckle on the left
side, and the upper one on the right side (due to the positions
of the cables after earphone installation). Cut off the excess
length on each cable tie.
