Adjusting the UI 765 to your telephone
Use the switch at the bottom of the housing to adjust
the UI 765 to your telephone.
왘 First make sure that the handset and the headset are
connected correctly. The handset must be activated,
i.e. the Headset/Handset button must be in “down”
position. Check if you can hear a dial tone in the
handset. Press the Headset/Handset button to
activate the headset. Check if you can hear a dial tone.
Otherwise, please proceed as follows:
Set the ABC switch to the positions “A”, “B” and “C”
one after the other. In each position, check if you
can hear a dial tone. The switch is located at the box
bottom side.

When is the UI 765 ready for operation?
The UI 765 is ready for operation as soon as:
• it is connected to your telephone
• the battery is inserted
• it is adjusted to your telephone
If you disconnect the UI 765 from the telephone, it is
immediately put out of operation.
Setting the volume of the headset microphone
With the UI 765, you can set the volume of the headset
microphone: a soft voice is slightly amplified and a loud
voice is attenuated. The trimmer is located at the box
bottom side.
왘 Turn the trimmer to the position marked “1”.
왘 Make a call and speak into the microphone with a
normal voice. Slowly turn the trimmer until the other
party can hear you loudly and clearly.
Adjusting the speaker volume output to comply with
the EU Directive 2003/10/EC
The UI 765 allows you to limit the speaker volume output
in the headset to comply with EU Directive 2003/10/EC.
왘 Move the switch from position “square” to “tri-
angle” to reduce the speaker volume output according
to EU Directive 2003/10/EC noise at work.

Note:
The Universal Interface UI 765 is a special version featuring a reduced output level. Even with the volume of
the Interface set to the maximum value, the signal
transmitted by the connected Sennheiser Communications headset will never exceed the maximum of 85 dB
(A) per day as a time-weighted average* value, which
is in compliance with the EU Noise Directive**.
* The time-weighted average value is based on a breakdown of a typical working day and measured as the
sound pressure level with a B&K HATS (Head And Torso
Simulator)
** EU Directive 2003/10/EC on the minimum health
and safety requirements regarding the exposure of
workers to the risks arising from physical agents
(noise)

Adjusting the sound clarity of the headset speaker
With the UI 765, you can adjust the sound clarity of the
headset speaker. Annoying background noise coming
through the headset speaker is filtered out and speech
intelligibility is thus enhanced.
왘 Press the button to filter out annoying background
noise.
Button down: speech intelligibility enhancement
system is activated
Button up: speech intelligibility enhancement
system is deactivated
Selecting the source — PC or telephone
왘 Press the button to select the source — PC or tele-
phone.
Button down: PC is selected as the source
Button up: telephone is selected as the source
10
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 outputting “incoming volume”, and “transmitted volume” is
picked from “incoming volume” by using the sidetone.

Cleaning the UI 765
Only use a soft — and, if necessary, slightly damp —
cloth for cleaning the UI 765. Do not use any solvents or
cleansing agents as these can damage the varnish of the
UI 765.
