Introduction
General
This installation guide has been prepared to provide the basic information necessary to install WLL terminal. This guide is not intended to be definitive, because different types and models of premises will require different installation
work. The information given is for general guidance only.
The terms of warranty demand that this WLL terminal be installed by a qualified
installation facility. An end user should never attempt to install this WLL terminal
without qualified assistance, as the installation requires special tools and knowledge.
Please refer to the telephone’s user guide for instructions on the telephone’s
operation, care and maintenance, including important safety information.
Installation
Technical Documentation
This section aims to give required information for installing the phone into a
premises. Read this instruction carefully in order to minimize the problems and
malfunctions.
The suggested installation concepts give only general ideas about positioning
of the unit. The installer should rely to his own skills and common sense when
choosing the locations.
The end user should never attempt to install the terminal by himself, as the
work requires special tools and knowledge. The terms of warranty also demand
that the terminal is installed by the a qualified installation company.
Selecting Locations
The best guide for selecting the locations of the units is your own experience,
skills and common sense. However, some aspects requiring special attention
will be discussed here.
The location of the telephone terminal is very important. Negotiate the place
with the customer.
The place for installation must be clean and dry. The terminal operating temperature range is –10°C...+55°C.

Check first the field strength at the installation location. RSSI (Received Signal
Strength Indication) can be measured by channel display function. A location
where the RSSI is between –50 dBm and –95 dBm is good.

Installation to the wall is preferred. It is very important to install the terminal as
shown in the figure below. The routings of the power supply and 2–wire cables
are important. They must be routed as far as possible from terminal‘s antenna.
TFK–1
The Monitoring handset HSN–5 is used to determine the signal strength at the
transceiver location. If the signal is weak, a better antenna must be used
instead of the portable antenna.

Technical Documentation
Using the handset HSN–5 to determine signal strength
Connect handset to system connector of TFE/K–1, using AFW–2.
Enter the security code to enable using of the handset. The security code is
calculated from the terminal’s IMEI, which can be viewed by pressing the Alpha
key while the phone is in security query state.
The network monitor display no 1 can be used to view signal strength.
Normally the network monitor display is displayed on handset, if no other text is
on display. The screen can be cleared by pressing C–key.
The network monitor displays can be scrolled using the arrow keys. A particular
display number can directly accessed from Menu 9.

The Antenna
The most important component of the installation is the antenna. The location
of the antenna as well the quality of the antenna and its installation have a considerable influence to the overall performance of the whole system. Therefore it
is necessary to emphasize some aspects, which too often have caused unnecessary service work.
The antenna shall be mounted in a position such that no part of the human
body will normally rest too close to any part of the antenna, unless there is an
intervening metallic screen, for example, the metallic roof.
If the internal antenna is not sufficient, an external window antenna or bi–directional high gain antenna must be used.*
Try to route the antenna cable so that possible sources of disturbances are
avoided. The shorter the antenna cable, the smaller the attenuation is, and the
better the performance of the antenna. The radio equipment shall be connected
to the antenna via a non–radiating cable (eg. coaxial cable).
Power Distribution
TFK–1
Testing
Connect the ACW–2 to the mains outlet. Route the supply cable so that there is
no danger to anyone.
Once installed, the equipment should be tested to ensure that it is operating
satisfactorily.
Use the landline phone to make a call and receive a call. During a call listen to
possible disturbances. If any disturbances exists move the position of the landline phone. For operating information refer to the ’User’s Guide’ supplied with
the phone.
* The external antenna must be connected to the antenna connector marked I.
The side of the basic antenna marked II must be connected to the antenna connector marked II when diversity is used. Note that the antenna halves can be
separated with a sharp knife.
