Plantronics 655 manual Problem, There is no dial tone in the handset, Solution

Problem

There is no dial tone in the handset.

I am unable to place calls using the headset.

Handset does not ring.

Solution

Make sure the battery is properly installed and fully charged. A full charge my take up to 16 hours. The

screen displays a full battery icon in the upper right-hand corner when the battery is fully charged.

Make sure the base and all cables are plugged in correctly. See “Setup” on page 4 for details.

The handset may not be registered to the base properly. Follow the steps in “Registering your handset with the charging base” on page 40 to re-register the handset with the base.

If is displayed on the screen, make sure the headset is fully charged, powered on, and within 33 feet of the handset. In the charging base, the indicator light changes from red to blue when the headset is fully charged.

If is not displayed on the screen, press the Headsetbutton for under 1 second. You should hear a beep in the headset and then the phone dial tone.

If the problem continues, see “Pairing with a new headset” on page 41 for instructions on how to re-pair your headset with your Calisto handset.

The ringer is turned off. Follow the steps in “Turning the ringer off” on page 26 for instructions on how to turn the ringer back on.

The base is not properly connected to a telephone jack. You can also plug another phone into the same telephone jack to check if there is a dial tone or if the line is out of service.
