INTRODUCTION

EAS Test

For stations participating in the Emergency Alert System (EAS) in the United States,
broadcast of EAS tones and data can be accomplished in three different ways:
1. Run EAS tones and data through the 5500.
Note that 5500 processing may not allow the full modulation level as required by
EAS standards. It may therefore be necessary to temporarily defeat the 5500's
processing during the broadcast of EAS tones and data. Placing the 5500 in its
BYPASS Test Mode can defeat the processing. The BYPASS GAIN control allows
a fixed gain trim through the 5500. See "Test Modes," on page 3-53 for more in-
formation.
2. Place the 5500 in Bypass mode locally.
A) Navigate to Setup > M
You can set the bypass gain with the B
right of the M
B) Begin EAS broadcast.
After the EAS broadcast, resume normal processing:
C) Set the M to O
ODE
This will restore the processing preset in use prior to the Test Mode.
3. Place the 5500 in Bypass mode by remote control. Then program any
two Remote Interface inputs for "Bypass" and "Exit Test," respectively.
A) Connect two outputs from your station remote control system to the
REMOTE INTERFACE connector on the rear panel of the 5500, according to
the wiring diagram in Figure 2-2 on page 2-3.
B) Program two GPI ports for B
in Remote Control Interface Programming starting on page 2-42.
C) Place the 5500 in bypass mode by remote control.
a) Switch the 5500 into BYPASS mode by a momentary command from your
station's remote control to the GPI port programmed as B
b) Begin EAS broadcast.
c) When the EAS broadcast is finished, switch the 5500 from B
a momentary command from your station's remote control to the GPI port
programmed as E
You may also choose to insert EAS broadcast tones and data directly into the
transmitter, thus bypassing the 5500 for the duration of the EAS tones and data
broadcast.
