Power Problems
The red power light on the handset does not flash when power switch is turned on.
Check that the batteries are inserted correctly. Install a fresh set of batteries, if needed.
The red power light on my base station is not flashing when the simulator is powered on.
Check that the cables from the simulator are installed in the base station correctly.
Audio Problems
The sound output from the simulator is low when using a microphone on my lapel.
Increase the microphone gain on the handset by moving the dial towards the plus sign.
Note: DIP switch 7 must be in the OFF position for this to work.
I’m hearing feedback from the microphone when I am close to the simulator.
Decrease the microphone gain on the handset by moving the dial towards the minus sign.
Note: DIP switch 7 must be in the OFF position for this to work.
The sound output from the simulator is too high or too low.
The volume level is configured at the factory for optimal performance. However, if you
want to adjust the volume level of the base station (located inside the simulator), set the
handset DIP switch 7 to ON. Remember to turn the handset power off and on after each
DIP-switch change. After this step is complete, you will be able to adjust the volume level
of the base station by adjusting the handset volume dial.
The sound output from the simulator is noisy when the speaker is not speaking.
You can use the noise reduction feature by setting the handset DIP switch position 8 to
ON.
The simulator voice output is cut off when the speaker is speaking quietly.
In this case, there are three possible options:
º Attempt to talk louder.
º Increase the microphone gain.
º Disable the noise reduction feature by setting the handset DIP switch 8 to OFF.
