4 FRONT PANEL OPERATIONS

The PRO4 Receiver's Front Panel is equipped with a 128x64 pixel LCD display, four
status LEDs; which indicate power, signal, update, and fault; and eight buttons: 1, 2, 3,
left( ), right ( ), up( ), down( ), and SET. Using this interface a user may navigate
through the PRO4's hierarchical menu to view, modify, and save receiver settings. The
four status LEDs serve as a quick reference for the current state of the receiver.

Status LEDs

4.1
There are four status light emitting diodes, each indicating a specific property of the
receiver. The following sections state their significance.

4.1.1 The Power LED

The POWER LED is on when the unit is plugged in and there is no problem with the
internal circuitry.

4.1.2 The Signal LED

The SIGNAL LED is used to indicate when the receiver has locked onto a signal or not.
If the signal LED is a solid green, the receiver is locked. Otherwise, the light will be off.

4.1.3 The Update LED

The UPDATE led indicates a software download/upgrade is in progress. When it is
blinking slowly (once per second), the download is in process. When it blinks fast (3x per
second), an upgrade has been successful and the receiver should be rebooted at a
convenient time (when audio is off air). The update LED will also be blinking if you
haven't activated your receiver unit with the NMS. See the Quick Start guide in Chapter
3 for activation instructions.

4.1.4 The Fault LED

The FAULT LED has three possible states. A red fault LED indicates that there is an
active fault condition affecting the receiver. A green fault LED indicates that there is no
active fault, but that there is either an active warning or a past fault in the fault history.
An off fault LED indicates that all is well and there are no past faults detected. The
STATUS menu (described below) will give you details as to which faults are active.
