Factory Default Settings
To return the amplifier to the factory default settings:
1. Unplug the power supply and then reconnect it.
2. The LED indicators will show a light pattern in the "Vol In" column. This
indicates the firmware revision. This will be followed by a green light
at the bottom of each column.
3. Within 20 seconds, press the On/Off button and Volume In (-) button
together, then release them.
4. The "Vol In" column will again indicate the firmware revision. This indi-
cates that the settings have been restored.
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/visitor microphone.
Volume In LED 8 will flash red if there is a
fault with the loop (e.g. a broken aerial).
