Possible Cause & Solution
•
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 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 was moved during a call.
→
Do not move the unit while on a call.
•
Objects are obstructing the microphone.
→
Do not obstruct the unit during calls. Keep your hands, as
well as common objects such as folders, cups, and coffee
pots away from the unit 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.
Possible Cause & Solution

The phonebook list is full.
→
Delete any unnecessary entries. The maximum number of
entries in the phonebook list is 500 for the KX-UT123/
KX-UT133/KX-UT136 and 100 for the KX-UT113.
