Training Tips
Upon surface entry, secure the mask to the face with one hand. Breathe
normally and
never
hold your breath. Upon descending, equalize, early
and often, prior to experiencing any pain or significant pressure. Stop
descending if equalization cannot be achieved or if pain occurs, descending
only
if proper equalization can be achieved.
If the mask requires adjustment while diving, tighten or loosen the straps
as required. Be careful not to overtighten. Inflate Buoyancy Compensating
Device (BCD) and swim on back if a surface swim is required. It is
recommended that removal of the mask occurs only after exiting the water.
This is important if the quality of water is contaminated.
Note: The diver should plan the dive to be back to the boat or beach
while air is still available in the tank.
INSTALLATION OF COMMUNICATIONS
The Spectrum FFM is designed to
accept Ocean Technology Systems
(OTS) communications. There are two
primary communication systems designed
specifically for the mask: The Buddy
Phone
®
(see
“Buddy Phone
®
Installation
Instructions” on page 19
)
and the OTS
earphone and microphone assembly (see
“EM-OTS-2 Installation Instructions” on
page 20
).
The Buddy Phone is a stand alone
communications system designed with the
transceiver mounted on the head harness
located on the right side of the diver’s head. The Buddy Phone has a built‑
in earphone.
The OTS earphone and microphone (EM) assembly is for all other through-
water and hardwire communications systems. Regardless of the system,
the EM assembly mounts to the mask in the same manner.
If the Spectrum FFM was purchased without communications equipment,
there will be a blanking plug installed in the communications port. This
consists of a plug on the inside (of the mask) secured with a threaded,
locking ring on the outside (Figure 17). To remove, use the OTS wrench
(P/N 137053-000) to unscrew the locking ring counterclockwise and
remove the plug from the inside.
