Q. I have a blank screen on my SPA9XX LCD, what is the problem?

A.

Step 1:
Check that the unit is using the correct power adapter (5Volts, 1Ampere rating).

Step 2:
Check if IP phone is plugged-in to a known working power outlet.

Step 3:
If the SPA9XX LCD screen still shows no display, then the unit is considered to be defective. Contact Support for replacement of the product.
