OpenPhone 27
General Information
General Information
The OpenPhone 27 is a cordless
telephone designed for operation in
the OpenCom 100 communications
system. In addition to convenient
softkey control of system features,
this telephone also offers a variety
of features that allow you to make
calls more easily.
You can also operate your handset
in other communications systems,
which means you can use the same
handset in different places.
Furthermore, it is possible to oper-
ate the handset in communications
systems made by other manufactur-
ers, as long as they meet the GAP
standard.
The OpenPhone 27 can be equipped
with a memory card that is included
in the package. Local settings for
the phone (including a local phone-
book with space for 100 entries) are
saved on this card along with the
device’s special ID code (IPEI). This
makes it possible for you to use
your locally stored data on another
terminal if the two devices have to
be swapped for any reason, as you
can take out your memory card and
insert it in the other telephone. You

can then make phone calls right
away - you don’t need to re-enrol
first.
The memory card is inserted under-
neath the batteries in the battery
compartment. To keep the two sep-
arate, an additional battery com-
partment locking mechanism has
been designed.
The following section (“Installation”)
will show you how to fit the Open-
Phone 27 with batteries and a
memory card.
Power Supply
This product requires a 230 V alter-
nating current power supply*. This
product can only be switched off by
removing the adapter plug from the
mains socket.
* The mains supply voltage in some countries
is 110 V. The adapter plug is designed accord-
ingly.
Use
This handset, like any cordless tele-
phone, operates using radio signals,
which do not always guarantee a
8
handsets produced by other manu-
facturers are used.
Additional Notes
• Depending on the digital trans-
mission in the frequency range
used and also on the technical
environment within the range
of coverage, silent zones may
occur. In this case, transmission
quality can be diminished by
multiple, short transmission
gaps. Slight movement out of
the silent zone will restore typi-
cal transmission quality. The
connection will be lost if the
handset is moved out of range.
• In order to avoid radio coupling
into other electronic equip-
ment, we recommend the maxi-
mum possible distance (min.
1m) between the charging sta-
tion / handset and other
devices (e.g. radios, loudspeak-
ers, etc.)
• The CE symbol on the product
confirms that it meets the tech-
nical guidelines on user safety
and electromagnetic compati-
bility valid at the time of issue
of the corresponding conformi-
ty declaration (see Appendix) in
line with European Directive
99/5/EC.
• Before using the handset, peo-
ple with hearing aids should
note that radio signals can cou-
ple into hearing aids and if
strong enough can cause an
connection being established under
all circumstances. For this reason,
you should never rely solely upon
any cordless telephone for essential
communication (e.g. medical emer-
gencies).
DECT and GAP
Your handset uses a digital radio
connection in accordance with the
DECT (Digital Enhanced Cordless
Telephone) standard for the con-
nection to the base station. The dig-
ital channel guarantees superior
voice quality without static or back-
ground noise. For signalling
between the communications sys-
tem and the handset, the Open-
Phone 27 uses the Generic Access
Profile (GAP).
The Generic Access Profile (GAP)
and the DECT standard define
processes used by digital cordless
telephones to establish connec-
tions. The GAP standard is not man-
ufacturer-specific so it is possible to
combine the communication sys-
tems and handsets of different ven-
dors. The basic functions (making
and receiving calls) are always pos-
sible with these combinations, but
other functions provided by your
OpenCom 100 communications sys-
tem together with your handset
(e.g. display of call numbers or call
charges) may not be available when

Battery polarity
Observe the correct polarity when
replacing the batteries. The +/-
symbols in the battery compart-
ment must correspond to the +/-
symbols on the batteries. The bat-
teries can be inserted without you
having to exert any force. Attempt-
ing to insert the batteries when the
polarity is incorrect may cause the
handset to be damaged.
Using the OpenPhone 27
with/without a memory
card
Your OpenPhone 27 is fully opera-
tional when you use it for the first
time even if you have not fitted it
with a memory card (in which case
the benefits described above will
not apply). If, on the other hand,
you have already used a memory
card in the phone (on which phone-
book data has already been saved)
and you then remove the card, the
OpenPhone 27 will cease to be
operational until a programmed*
memory card is inserted.

Important note on safety
Take great care handling the mem-
ory card. The contacts should be
free of dust, grease and moisture,
for example. Do not store your card
in a place where it will get hot (e.g.
through direct exposure to sun-
light). Avoid bending the memory
card, as the contacts may get dam-
aged as a result.
• First of all, press the memory card
out of the plastic frame holding it
using your finger.
• Then push the memory card
cover in the battery compartment
in the direction of the arrow
(OPEN). Tilt the cover upwards
slightly.
Make sure you never touch the
gold contacts that are now visi-
ble, as static discharge could lead
to the device becoming defective.
• Press the memory card under the
two semicircular protuberances
(a) so it slides into the memory
card compartment. Make sure the
contacts are face down as you do
so and that the notched edge of
the memory card is at the bottom
left.
• Press the memory card down
until it snaps firmly into place.

In order to achieve long operating
times, you should discharge the
battery at intervals by not placing
the handset in the charging station
and leaving it switched on until it
switches itself off. Only use this
method to discharge the battery.
Extreme fluctuations in temperature
have an effect on the charging
capacity of the battery.
Charging the Battery

damage when other types of
rechargeable battery or normal bat-
teries are used.
Charging and Operating
Times
Charging time: 5-6 hours (for a fully
discharged battery).
Talk time: up to 14 hours (fully
charged).
Stand-by time: up to 140 hours
(fully charged).
Note
Batteries with an unknown charging
status are fully charged in approx.
14 hours.
Charging and Discharging
The battery can be charged and dis-
charged hundreds of times, but it
will eventually be used up. When
the operating time (i.e. talk and
stand-by time) has become notice-
ably shorter than normal, the bat-
tery should be replaced.

Your handset has a battery manage-
ment system that has to determine
the limits of the battery charging
status before it can display an accu-
rate charge level.
Your Telephone's Features
Using Your Telephone
When the battery has been
replaced, the charge level is not cor-
rectly displayed until a whole
charge and discharge cycle has been
completed.
When the handset is in the charging
station, the flashing or lit sections
indicate charging and the charge
level.
Charge Warning
When the battery capacity is nearly
exhausted, the battery symbol will
flash in the display and you will hear
the battery warning tone (if the bat-
tery warning tone is switched on). If
you are making a call at the time,
you still have up to five minutes of
talk time before the handset switch-
es itself off.
If you are not making a call and the
handset is not in the charging sta-
tion, “Battery empty” appears in the
display. You can no longer make a
telephone call now.
