Troubleshooting

Issue

Sound cuts out; I can hear myself through the speaker.

Possible Cause & Solution

The unit has not yet adapted to the environment for the current call.

Speak in turns with the other party at the beginning of a conversation. This allows the unit to adapt to its environment so that both parties can speak effectively.

If using a PS, you are pressing [] before the PS call has started.

Start the call using the PS, then press [].

If using a PS, the PS Cable is not firmly connected to the PS.

Make sure the plug of the PS Cable is inserted fully into the PS, otherwise echoing and feedback may occur.

If using DSL service, a device connected between the unit and the telephone jack is causing interference.

Connect the unit directly to the telephone jack if possible, and/or consult your DSL service provider.

You are too far away from the microphone.

Try speaking closer to the microphone.

The environment is not suited to speakerphone calls.

Do not use the unit within 2 m (about 6.5 ft.) of projectors, air conditioning devices, fans, or other audible or electrical noise emitting devices.

If using the unit in a room with windows, close the curtains or blinds to prevent echoes.

Use the unit in a quiet environment.

The unit or an External Wired MIC was moved during a call.

Do not move the unit or an External Wired MIC while on a call.

Objects are obstructing the microphone.

Do not obstruct the unit or an External Wired MIC during calls. Keep your hands, as well as common objects such as folders, cups, and coffee pots away from the unit and the External Wired MIC during calls.

The other party is using a half-duplex speakerphone.

If the other party is using a half-duplex speakerphone, sound may cut out occasionally during calls. For best performance, the other party should use a full-duplex speakerphone.
