CIRCUIT DESCRIPTIO N

t	16 . Semi-self test functio n
	Semi-self test is started by turning the POWER switch o n
	with the 4 (AM) and T-F SET switches pressed .
	This test provides a method of testing the TS-440 digita l
	system in a shorter time during production or servicing . The
	test enables the following :

1.Circuits which are difficult to test during program execu- tion to be tested easily . For example, dynamic data ca n be ouput as static data .

2.Items on which information is held only by the CPU an d is not available to the user to be tested .

a.Approximately threshold level inpu t

b.Incorrect input due to input pin faul t

Operation procedure

1 . POWER SW OF F

2 . The power switch on while pushing switch 4 (AM) an d switch T-F SE T

3.The test number has starts from "0" to "56" and EN D when turn the VFO knob clockwise .

Operation chart shows as follow .

4.To reset SEMI-SELF TEST function, Power switch OFF .
