Troubleshooting
Problem 1
The VSP-M station does not receive calls. There is no signal tone.
The issue could be that no extension number is set.
Possible solution:
Verify that the station has the correct address for the extenstion
number set on the DIP switches (see Figure 1).
Problem 2
VSP station receives calls from both groups.
Possible solutions:
–
Verify that only DIP switch 11 for GROUP 0 or only DIP
switch 12 for GROUP 1 are set to the ON position.
–
Remove jumpers from pins J2 and J3.
Problem 3
When mounting sparepart board, no call tone is heard.
Possible solution:
When using boards with inductors, remove jumpers from pins J6
and J7/J8 and insert a jumper on pin J9 located to the left of the DIP
switches.
