Verify that the fuse is good by checking the continuity with a multi-meter. If the fuse
is open, replace with the same type: 3.15 Amp, 250V, Fast Acting. Close the front
panel; re-install the screws and re-test the communicator. If the communicator still
appears dead, contact Amron for further assistance.
5.5.4
LOW VOLUME
Check the volume control settings and adjust if necessary. Check the diver
connections and verify that the diver and tender are connected as intended. Verify
the wires and connector are clean and tight. Check the BATTERY CONDITION
INDICATOR and test the battery if necessary. If the problem persists, disconnect
the diver umbilical and perform the communicator check out procedure per section
5.1 or 5.2. If the communicator fails the check-out procedure, contact Amron for
further assistance.
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.
5.5.5
GARBLED VOICE TO 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 or 5.2. If the communicator fails the check-out procedure, contact
Amron 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.
5.5.6
GARBLED VOICE TO 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 or 5.2. If the communicator fails
the check-out procedure, contact Amron 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.
