5.4.8 Self Test

The Self Test facility does some simple checks on the EPROM and the EEPROM and is activated in two ways :

(1)With initial power on.

(2)By user selection in the test menu.

The power on displays are a shorter version of menu activated Self Test and are as follows :

(This is a break down of the testing procedure in step 1 above)

Checks the details of the interface module fitted.

	or in the case of failure:		EPROM Fail


or	EEPROM Csum Fail	or	EEPROM Fail
