The front panel LED display is used to view the status of the selected input of any room.
1. INPUT SELECTOR LEDS
There are 8 LEDs arranged in 2 rows, in the front panel display. These LEDs indicate the selected input (A1 through AV8) of each room. To view the selected input of any room, the appropriate room selector switch described in 3 below, must be operated.
2. ROOM LEDS A Through D
The 4 LEDs located at the bottom of the front panel display indicate which room has been selected by the room selector switches.
3. ROOM SELECTOR SWITCHES
There are 4 room selector switches located behind the front panel, which are accessed through the 4 holes beneath the display window. These switches are operated by inserting the plastic rod (provided) through the access hole in the front panel and pressing gently. When any of these switches are operated, the appropriate room LED above it will light and the input selector LEDs will indicate which input has been selected by that room. To find out which input has been selected in another room, simply operate the appropriate room switch.
4. INFRARED TRANSMITTER
Hidden behind the front panel window is a high power I/R transmitter that transmits data received from any of the infrared code inputs.
