Manual

Note:

If the PC is selected as the source, the button  and

volume control  are deactivated. Consequently, you

cannot mute the headset microphone or set the volume

of the headset speaker using the UI 765 but you have

to set the volume via your PC.

Setting the volume of the headset speaker

왘 Use the volume control  to continuously set the

volume of the headset speaker.

“Dynamic Volume Control” ensures that the volume set

via volume control is kept constant, even if the other

party speaks with varying volumes.

The functions of your telephone

Even with the UI 765 connected, you can use all functions

of your telephone as usual. To make a call, lift the handset

and dial a phone number. To end a call, replace the

handset. The ”hands-free conversation” function can also

be used as usual.

Using the dictaphone output

The output can be used to record a conversation in both

directions. The dictaphone output of UI765 is only output-

ting “incoming volume”, and “transmitted volume” is

picked from “incoming volume” by using the sidetone.
