If the communicator checks out, then the problem is likely in either the diver
umbilical communication cable, the wiring of the diving hat/helmet, or the diver's
microphone/earphone.
6.3.5
GARBLED VOICE TO THE DIVER
The TENDER TO DIVER VOLUME control is set too high. Reduce this control until
the voice signal clears. If this does not solve the problem, check the diver's
earphone for corrosion or other defect. Replace if necessary. If the tender is using
a headset, remove the headset and communicate to the diver by pressing the
PUSH-TO-TALK BUTTON and talking into the PANEL SPEAKER. If this solves the
problem then the tender headset may be wet or defective. If the tender is using the
PANEL SPEAKER to talk to the diver, check the speaker for any accumulated
water. Drain the speaker if necessary. If these steps do not solve the problem then
disconnect the diver umbilical and perform the communicator check out procedure
per section 5.1. If the communicator fails the check-out procedure, contact Amron
per section 2.2 for further assistance. If the communicator checks out, then the
problem is likely in the diver umbilical communication cable. If possible, substitute
a known good cable to verify.
6.3.6
GARBLED VOICE TO THE TENDER
The DIVER TO TENDER VOLUME control is set too high. Reduce this control until
the voice signal clears. If this does not solve the problem, check the diver's
microphone for corrosion or other defect. Replace if necessary. If the tender is
using a headset, remove the headset and listen to the diver using the PANEL
SPEAKER. If this solves the problem then the tender headset may be wet or
defective. If the tender is using the PANEL SPEAKER to talk to the diver, check
the speaker for any accumulated water. Drain the speaker if necessary. If these
steps have not solved the problem, then disconnect the diver umbilical and
perform the communicator check out procedure per section 5.1. If the
communicator fails the check-out procedure, contact Amron per section 2.2 for
further assistance. If the communicator checks out, then the problem is likely in the
diver umbilical communication cable. If possible, substitute a known good cable to
verify.
6.3.7
DIVER CUTS OFF
This is usually caused by an intermittent connection between either the umbilical
and the diver communicator or the umbilical and the diver's hat/helmet. The
intermittent connection could also be inside the diver's hat/helmet. Check all
connections to verify that they are clean and tight. If the problem continues,
substitute the communication cable with a known good cable. If this solves the
issue, then the communication cable in the original umbilical is damaged and
needs to be replaced or repaired. If none of these solutions fixes the problem,
contact Amron per section 2.2 for further assistance.
6.3.8
FEEDBACK - FULL DUPLEX (4-WIRE) MODE
There are two forms of feedback that can affect the 2810E: acoustic feedback and
cable crosstalk. Acoustic feedback occurs when an active microphone is close
