important			notes		on	start-up
The	MAMMOMAT			2	is adjusted,			programmed and tested	in	the	factory, leaving
only	the function tests				to	be	performed.
When	the	measurements				to	be	made (kV, más, etc.) are	within		the tolerances in
these	instructions,			these		indicate that the settings made			in	the	factory have not
changed		and	the	equipment			is	fully serviceable.

The measured values marked with > shall be entered in the “Start-up” column in the test certificate provided.

The Service PC is required only for programming according to:

-Section.8 Start-up and functional test of the lontomat PM

Programming the "Correction curve"

Setting	the	"Sensitivity"	(film density)
Setting	the	"Sensitivity	correction“ (adaptation to different exposure
techniques)

Note:	If the generator	is switched off	with the Service	PC connected, wait
	approximately	5 seconds before	switching it on	again.

Checking and recording for the DHHS area of application

In the area of application of DHHS regulations, additional measurements and checks must be made according to the instructions "DHHS Maintenance Schedule and User’s Spot Checks" RB7-211.101... (included in the "DHHS

supplements to the operating instructions" RB7-211.203...).

Sec. Required labels

Sec. Radiation-on indicators

Sec. Manual termination of exposure

Sec. Check the maximum adjustable mAs with the following kV-values Sec. Reproducibility

Sec. kVp-accuracy

Sec. mAs-accuracy

Sec. Automatic exposure control

The results	must be	recorded in "Test	certificate" RB7-211.037....
Some of the	values	to be determined	can be taken from the test certificate.
