OpenPhone 28
Installation
The port is located on the upper
right part of the handset. Carefully
pull off the protective covering of
the port.
Connecting the headset
Push the plug of the headset com-
pletely into the port until it audibly
snaps into place.
For information on using the head-
set, please read the user guide.
The headset enables hands-free te-
lephony. Your handset automati-
cally registers when a headset is
plugged in. The microphone and the
earpiece of the handset are then au-
tomatically
switched off
. The loud-
speaker can be switched on if you
want others to listen in.
The handset rings for incoming calls.
Everything else functions in the
usual manner. To adjust the
ear-
piece volume
, long press up or
down on the arrow keys until a low
confirmation tone can be heard. (see
Setting the volume
starting on
page 26).
Recommendation for Headset
Operation
If you connect the headset to other
electronic devices, potential ex-
tremely loud acoustic signals or feed
back noise can lead to hearing dam-
age (acoustic shock). Hearing pro-
tection against loud noises is not
guaranteed if the headset is used
with other devices. Only use this
headset in conjunction with the
OpenPhone 28.
Belt Clip
The clip is attached on the back of
the handset with two small screws.
Belt clip
Please note:
Attach the hand-
set vertically on your clothing; this
ensures the correct functioning of
the “
Automatic Emergency Call (Man-
down Call)
” (see also page 47).
