Common Problems and Solutions
I do not get a dial tone on my handset. Why?
This may occur under any of the following circumstances:
The power adapter is not connected properly and the power button LED is not illuminated.
No signal.
The home phone cable is not securely plugged in.
Does 911 work on my T720?
Yes, but since the T720 is designed for an indoor environment, please be prepared to provide your location inside the
premises to public service personnel. The GPS chipset embedded in this device will work best if the device is located
near a window or other opening.
How do I perform a Factory Reset?
Using the reset button. Please check ‘Resetting Your Device’ section.
Why do I get the recording, “Call cannot be completed as dialed” ?
Please check the number to ensure that you are dialing correctly, without pausing longer than two seconds between
dialing digits.
