Problem

The caller cannot hear me.

I am having trouble hearing the caller.

There is static and/or interference on the call.

Solution

Check the handset screen to make sure the call is not muted.

If you are using the headset, make sure you have transferred the call to the headset. See “Switching calls between handset, headset, and speakerphone” on page 10 for instructions.

Make sure the headset microphone is pointed toward your mouth for optimal audio performance.

If you experience low volume on the headset, increase the volume of the headset. See “Adjusting call volume using your headset” on page 14 for instructions.

If volume is low on the handset, increase the volume of the handset. See “Adjusting call volume” on page 10 for instructions.

Your handset might be out of range of the base. Move the handset closer to the base. The maximum handset- to-base range is 300 feet in optimal conditions. The range depends on environmental conditions.

Your headset might be out of range of the handset. Move the headset closer to the handset. The maximum headset-to-handset range is up to 33 feet. If you move beyond the range of the headset, the call will drop.

If the base is in close proximity of microwaves, ovens, TVs, and any electrical appliances, try moving it away from those devices.

If you have DSL on the same phone line, be sure that you are using a DSL filter between the base and the telephone jack. You may obtain a DSL filter from your DSL service provider.
