Fault Diagnosis LEDs
• Volume In LED 8 will stay red if there is a
fault with the staff microphone.
• Volume Out LED 8 will stay red if there is a
fault with the customer microphone.
• Volume In LED 8 will flash red if there is a
fault with the loop (i.e. a broken aerial).
Using the System
For best possible performance:
1. Ensure the customer and staff volumes are turned completely down.
2. Adjust staff volume (Volume In) to a comfortable level.
3. Increase customer volume (Volume Out) until feedback is heard.
4. Decrease customer volume (Volume Out) until feedback is just eliminated.
Check that the amplifier is fully functional by ensuring the red ‘fault’ light
is NOT displaying.
5. If there is insufficient volume even after you have adjusted the volume
controls, enter engineers mode and raise max volume settings. Exit
engineers mode and repeat initial setup.
6. The system is now ready to use.
