Try to power cycle your CLEAR Voice Adapter & CLEAR Modem by unplugging the power cord (the small black wire) for 10 to 15 seconds and then plugging it back in. Wait for the light to turn solid green before proceeding. Also, try plugging the phone you’ll be using with your CLEAR Voice service into a normal phone jack at home to make sure it’s working properly. Make sure the telephone plugged into the CLEAR Voice Adapter is plugged into the Phone 1 port. Make sure that all the cables and adapters are securely plugged in and that all of the modem and CLEAR Voice Adapter lights are lit showing power.
