4. IF IT IS NOT WORKING:
NO PHONE CONNECTION:
-	 Check	if	the	programming	switch	is	set	to	1.	
-	 Check	the	connection	by	connecting	the	telephone	direct	to	the	main	line.
-	 Check	the	power	on	the	Trunk	terminals	(A,	B;	TRUNK,	TRUNK).	This	must	be	the	same	as	on	the	telephone	line	terminals	(TEL).
NO CONTACT WITH THE SIMPLEBUS SYSTEM:
-	 Direct	after	programming	the	Simplebus	code,	the	LED	shows	the	status	of	the	bus	line.	If	the	LED	blinks	4	times,	measure	than	the	power	between	the	bus	line	terminals	
(L - L). (This must be between 17 and 30VDC).
-	 Did	you	program	the	right	code?	If	any	doubt,	please	follow	the	programming	procedure	mentioned	in	chapter	2.
-	 If	the	telephone	rings,	but	you	are	not	able	to	speak,	it	could	be	that	the	interface,	the	reason	could	be	the	programmed	bus	mode	in	the	interface.	This	could	happen	if	you	
forgot to program the interface, while in the programming procedure the bus type automatically will be adapted. Please follow the programming procedure of chapter 2.
NO DIVERSION:
-	 Be	sure	that	the	number	of	the	diversion	has	been	programmed	properly.	If	the	interface	is	connected	to	a	telephone	switchboard	(PABX),	normally	there	must	be	programmed	
a "0". For some switchboards it could be necessary to program a pause after the first number, by adding ## (wait after each # for an acknowledge).

* If you use this function, you also must setup the Simplebus mode (dafault SB1). If address 000 is programmed, the interface will activate on all codes.
If	the	system	is	working	fine,	but	it	is	desired	to	change	the	factory	settings,	please	follow	the	instructions	below:
Important: An analogue telephone must be connected to the output of the telephone interface. 
1	Set	the	programming	dipswitch	to	the	position	"ON".	
2	Choose	between	on	of	the	codes	mentioned	in	the	table	followed	by	the	required	setting.
Example:	setting	internal	call	time	to	40	sec.	(line	2)	choose:
After programming a confirmation beep will sound.
3 Set the programming dipswitch to the position "1" to enter into the normal mode.
