Troubleshooting

Issue

While on speakerphone, the other party’s voice breaks up, or I hear an echo of my own voice.

I cannot hear the other party through the handset.

Possible Cause & Solution

•Just after a call begins, the unit may not have yet adjusted itself to the call’s environment.

→Just after a call begins, take turns with the other party talking to each other. The unit will adjust itself in accordance with the call environment so that both you and the other party can hear each other as clearly as possible.

•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 (7 ft) of radios, televisions, office equipment, microwave ovens, air conditioners, or other devices that emit electrical noise.

→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 was moved during a call.

→Do not move the unit while on a call.

•The microphone is blocked.

→During a call, avoid blocking the microphone with your hands or other objects.

•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.

•The handset is not connected correctly.

→Check whether the handset is connected correctly. If it is not connected correctly, connect it again (Page 100).
