2-Wire Check
This procedure checks the communicator functions in the 2-Wire mode.
1. Set all the volume controls to the mid-scale (halfway) position.
2. Turn the SPEAKER SWITCH off to avoid acoustic feedback.
3. Turn on the communicator and verify the BATTERY CONDITION
INDICATOR is on or blinking. If the LED does not come on at all,
then replace or recharge the battery. If that does not resolve the
problem, then go to the troubleshooting section to determine the
cause.
4. Identify the microphone and headset leads. When using an Amron
headset, the microphone is the red banana plug and the headset is
the black banana plug.
5. Plug the microphone lead into the TENDER HEADSET (black) jack
and the headset lead into the DIVER MICROPHONE (red) jack.
6. Don the headset. Talk into the microphone while pressing the PUSH-
TO-TALK BUTTON. You should be able to hear yourself in the
headset. Adjust the TENDER TO DIVER VOLUME control and verify
that the level can be adjusted to a comfortable level.
7. Unplug the microphone lead. Turn on the SPEAKER SWITCH. Press
the PUSH-TO-TALK BUTTON while speaking into the PANEL
SPEAKER. You should be able to hear yourself in the headset.
Adjust the TENDER TO DIVER VOLUME if necessary and verify that
the level can be adjusted to a comfortable level.
8. Plug the microphone lead into the TENDER HEADSET (black) jack.
Short the PUSH-TO-TALK JACK (yellow) with a short piece of wire.
Talk into the microphone and verify that you hear yourself in the
headset. Remove the short. Turn off the SPEAKER SWITCH.
9. Move the microphone lead to the DIVER 1 MICROPHONE (red) jack
and move the headset lead to the TENDER HEADSET jack.
10. Talk into the microphone and verify you can hear yourself in the
headset. The PUSH-TO-TALK BUTTON should not be pressed.
Adjust the DIVER TO TENDER VOLUME control and verify that the
level can be adjusted to a comfortable level.
11. Repeat steps 9 and 10 for the remaining diver channels.
This completes the check of the 2-Wire function of the communicator. If at
any point in the test you were not able to hear yourself in the headset as
indicated by the test, refer to the troubleshooting section to determine the
cause.
