The following definitions apply to
Table 6
:
Blink - LED is OFF for 1 second, and then blinks on count times (ON for 250 ms
and OFF for 250 ms). This overall pattern is continued.
Flutter - ON for 50 ms, OFF for 50 ms, repeating….
AMBER - RED and GREEN turned ON at the same time.
AMBER - RED and GREEN turned ON at the same time.
Note: ms = 1/1000 second
The conditions are listed in the order of their display priority with highest priority at top. For
example, if the unit is in Satellite Search Mode, and there is an NTSC/PAL mismatch, the LED
should indicate the Satellite Search condition.
Note that the alarm conditions are those conditions preventing the delivery of video.

PROCEDURE
Apply power to the receiver. The unit performs a quick checksum test on the EEPROM
(electrically erasable programmable read only memory). When the test passes, the unit initializes
various devices and configures itself according to the EEPROM settings. It then waits for the
receiver board to complete its power up test, which takes about 10 seconds. When the receiver
board passes its test, the IRD sends a tune request to the receiver board and the Welcome
Banner, shown in

displays on the terminal screen. Otherwise, “ALARM: INSTALLATION” displays on the
monitor screen. The IRD then enters alarm mode until all of the alarm conditions are cleared.
