OTS MK-7 BUDDY-LINE User Manual page 10

4.2.7 After all connections are made, you can test the system. Have the diver(s)
don the full-face mask. The tender will don the headset with boom
microphone. The boom microphone should be positioned 1/4 inch from
the tender's lips (keep the microphone as dry as possible).
The MK-7 Buddy-Line will power up the moment the headset and boom microphone
are connected. There is no on/off switch. As long as the headset is plugged in, the
MK-7 will be on and drawing power.
The tender controls all volumes. The volume control labeled "Tender" controls the
volume of the tender's voice to both divers. The individual volume controls labeled
"Divers" control what the tender hears from each diver. The tender should adjust
all volumes a little at a time until everyone can hear well. Rotating any control
clockwise brings the volume up. Counterclockwise rotation brings the volume down.
1. If the diver is set up properly, the tender's pulling on the ComRope should
pull on the diver's hand-hold first. If the diver does not have the hand-hold,
the strain should go to the belt "D-ring," not the diver's full-face mask or
diver's earphone-microphone assembly.
Ensure the diver is dressed out such that no unnecessary loops can entangle
him.
2. Excessive volume will cause distortion and hinder communications. Adjust
all volumes slowly until everyone hears clearly. A good rule to follow is "Less
volume is better than too much noise."
1. The diver should be dressed in such a manner that he can disconnect from
the ComRope and from the earphone-microphone assembly. If it becomes
necessary to make an emergency ascent, if the diver has to break voice
communications, and if line pulls cannot be established, the diver should
surface and establish communications as soon as possible.
2. We do not recommend you rely solely on MK-7 Buddy-Line voice
communications. A back-up safeguard, such as line pulls, should be
established and practiced (Table 1).
If you connect the headset with boom microphone and the MK-7 does not power
up, verify the batteries are fresh (new).
