TROUBLESHOOTING

Possible Cause
Failure to wash and
lubricate connectors
after use in salt water.
Batteries are defective
or dead.
Connectors are not
properly connected or
are damaged.
Headset with boom
microphone is not
plugged in.
Diver(s) cannot hear
topside, but topside can
hear divers.
Diver(s) can hear
topside, but topside
cannot hear the divers.
Tender and divers hear
light music over the
intercom.
You are speaking
too loudly into the
microphone.
Your volume controls
are set at too high a
level.
Remove salt water residue or corrosion
from the unit by wiping it with a cloth
saturated in warm freshwater (use
detergent if necessary). Periodically
check the connectors to ensure they are
clean and lightly lubricated with a high-
grade silicone grease.
Replace alkaline AA batteries with fresh
ones.
Clean and check all connectors. Replace
damaged ones.
Connect headset; unit should power up.
Check topside microphone and make
sure the tender volume is turned on and
the microphone is about 1/4 inch from
the tender's lips.
Check all connections. Check the diver's
microphone. Verify the diver's volume
controls are turned up.
This happens if you are using an
unshielded umbilical and are close to
a transmitting station. The only way
to solve this problem is to change to a
shielded ComRope.
Speak with more moderate volume,
slowly and distinctly.
Slowly adjust your volumes as to not
overdrive the system.
