Table 4--1 gives the proper power--up procedure for the PRIMUSR 880 Digital Weather Radar System.

Step			Procedure
1	Verify that the system controls are in the positions
	described below before powering up the radar system:
	Mode control:		Off
	GAIN control:		Preset Position
	TILT control:		+15
2	Take the following precautions, if the radar system will be
	operated in any mode other than standby or forced
	standby while the aircraft is on the ground:
	D	Direct nose of aircraft so that antenna scan sector is
		free of large metallic objects such as hangars or
		other aircraft for a minimum distance of 100 feet (30
		meters), and tilt the antenna fully upwards.
	D	Do not operate the radar system during aircraft
		refueling or during refueling operations within 100
		feet (30 meters).
	D	Do not operate the radar if personnel are standing
		too close to the 120_ forward sector of aircraft.
		(Refer to Section 6, Maximum Permissible
		Exposure Level, in this guide.)
	D	Operating personnel should be familiar with FAA AC
		20--68B, which is reproduced in Appendix A of this
		guide.
3	If the system is being used with an EFIS display,
	power--up by selecting the weather display on the
	EHSI. Apply power to the radar system using either
	the indicator or controller power controls.
