Diver Earphone Volume: WARNING: pressing the push-to-talk button
could shock the divers in the event that the diver microphone mounting screws
are in direct contact with the diver's mouth. Ensure that the microphone
is placed away from the Diver's mouth or the screws are insulated with a
rubber boot. Allows the Tender to control the earphone volume of each
diver. Pressing down on the knob activates the PTT for that diver, which
mutes all the microphones of all the other divers. (But not the tender.)
Diver Earphone and Microphone Connectors: Used to connect diver
intercom cables to the MK-III. Diver earphone and microphone are available
in banana, 5-pin MS, and AMP connector configurations.

DAISY CHAINING
In the event that you have more than three divers, it's possible to connect two
MK-III surface units together, allowing for up to six divers to communicate.
To connect two units together, connect an RCA cable from the Line In
connector from one unit to the Line Out connector to the second unit. Repeat
this process for the Line Out connector to the Line In connector.

AFTER THE DIVE
After each use, be sure to disconnect all connectors from the MK-III panel. If
you have been using the battery for power, recharge the battery for the next
use. Follow the preventive maintenance instructions presented in Section
5.1 to maintain your MK-III in optimal condition
If the MK-III is going to be transported airborne, OPEN BOTH SAFETY
VENTS TO DEPRESSURIZE THE UNIT'S INTERIOR DURING
FLIGHT. Failure to do so will cause the unit to seal shut. The valves are
located on the upper and lower halves of the case's front with the panel facing
upward and are opened by fully rotating counterclockwise. Before using
the MK-III again, close the ventilation valves (by rotating fully clockwise)
to prevent water from entering the case.
