Installation location/Range
Installation location
Do not position the base station on a me-
tallic surface or in the immediate vicinity of
other electronic appliances such as hifi
equipment, office equipment or microwave
ovens; this will prevent any mutual inter-
ference. Also avoid installing the base sta-
tion in the vicinity of heat sources, such as
radiators or in direct sunlight. For the best
possible range we recommend a central in-
stallation location at the centre of your ra-
dius of action. Avoid installation in niches,
small rooms and behind steel doors. To pre-
vent radio feedback in other telephones,
we recommend the largest possible dis-
tance (min. 1 m) between the base station
or handset and the other telephone.
Setting up your telephone
Your telephone is designed to be used un-
der normal operating conditions. Modern
furniture is treated with an endless variety
of lacquer and plastic coatings. Therefore,
it cannot be excluded that some of these
substances may contain agents which will
attack or deform the plastic feet of the base
station. If the equipment feet are chemi-
cally altered in this way, they may leave
unsightly marks on the surface of furniture.
Ascom cannot accept any liability for dam-
age of this kind. We recommend that you
use a non-slip underlay for your telephone,
especially on new furniture or furniture
treated with lacquer-based preservatives.
Range
The radio range is up to 300 m in the open.
Ambient conditions can affect the range,
as can room and building-related factors.
The effective range is lower inside build-
ings than outdoors. Silent zones can occur
due to the digital transmission in the fre-
quency range used – and also within the
range, depending on the structural envi-
ronment. In such cases the transmission
quality can be affected by repeated, short
call interruptions. Normal call quality can
be restored simply by moving slightly out
of the silent zone. If the range is exceeded,
the call will be disconnected shortly after-
wards (if necessary switch on range warn-
ing tone).
Listening protection
The Ascom Avena 122/Ascom Avena 122
plus transmits the voice data between base
station and handset in cryptologically en-
ciphered form (scrambling). As a result the
tapping of your calls by other cordless tel-
ephones, radio receivers, scanners, etc., is
excluded.
Important information
Whenever you make a telephone call, the
handset and base station are connected
with each other via a radio channel. The
base station uses this channel for switch-
ing between the telephone network and
the handset. To ensure that no-one else can
make telephone calls at your expense us-
ing other cordless telephones, an ID code
is constantly exchanged between base sta-
tion and handset. If the codes do not match
up, the call is disconnected or prevented
from being set up in the first place.
