闭合跳开关后

Push the HF 1 switch light, on the No. 1 radio tuning panel (RTP-1), on the P8 aft electronic panel. Make sure that the switch light comes on.

Make sure that the internal blower fan on the HF transceiver operates when you transmit.

At the front panel of the transceiver for the applicable HF communication system (HF-1 or HF-2), push and release the TEST switch to do the BITE test of that system.

Make sure that these conditions occur:
1. The LRU STATUS and CONTROL FAIL LEDs turn red for one to three seconds. The KEY INTERLOCK LED flashes red for 45 milliseconds and then turns off for 2 seconds.
2.The LRU STATUS LED turns green and the other LEDs turn red for 1 to 3 seconds.
3.All LEDs go off for 1 to 7 seconds.
4.The LRU STATUS LED turns green and the other LEDs stay off. After 30 seconds, all LEDs are off.

NOTE:  Any of the three LEDs that come on red after the self-test is completed indicates a defective condition.
