Putting the UI 770 into operation

Adjusting a clear dial tone

왘 First make sure that the handset and the headset are con-

nected correctly. The handset must be activated, i.e. the
headset/handset button (see page 10) must be in “down”
position. Check if you can hear a dial tone in the handset.

왘 Press the headset/handset button to activate the headset.

Check if you can hear a dial tone in the headset.
Otherwise, 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.

Adjusting the volume of the headset microphone

The microphone volume control on the UI 770 allows you to adjust
the volume of the headset microphone: a soft voice is slightly
amplified and a loud voice is attenuated.

왘 Adjust the telephone to a medium volume level.
왘 Turn the microphone volume control to position “1”.
왘 Make a call and speak into the microphone with a normal voice.

Slowly turn the microphone volume control until the other
party can hear you.

Limiting the speaker volume

The EU switch on the UI 770 allows you to limit the speaker volume
of the headset to comply with EU Directive 2003/10/EC.

왘 To limit the speaker volume, move the EU switch from position

“square” to “triangle”.

8 | UI 770

Putting the UI 770 into operation

The UI 770 universal interface is a special version featuring
a reduced output level. Even with the volume of the UI 770
set to the maximum, 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).

When is the UI 770 ready for operation?

The UI 770 is ready for operation as soon as:

• the battery is inserted

• it is connected and adjusted to your telephone

If you disconnect the UI 770 from the telephone, it is immediately
put out of operation.

speaker. Annoying background noise coming through the headset
speaker is filtered out and speech intelligibility is thus enhanced.

왘 Press the sound clarity button to filter out annoying back-

ground noise.
Button down: Speech intelligibility enhancement is activated
Button up: Speech intelligibility enhancement is

deactivated

Selecting the source – PC or telephone

왘 Press the PC/telephone button to select the source – PC or

telephone.
Button down: PC is selected as the source
Button up: Telephone is selected as the source

If the PC is selected as the source, the mute button and
volume control are deactivated. Consequently, you cannot
mute the headset microphone or adjust the volume of the
headset speaker using the UI 770 but you have to adjust the
volume via your PC.

Cleaning the UI 770

Adjusting the volume of the headset speaker

왘 Use the volume control to continuously adjust the volume of

the headset speaker.

“Dynamic Volume Control” ensures that the volume set via the
volume control is kept constant, even if the other party speaks
with varying volumes.

Using the dictaphone output

The dictaphone output can be used to record a conversation in
both directions.
