The following points must be taken into account when installing and configuring a radio modem:

1. All operating voltages of all the equipment concerned must always be switched OFF before

connecting the serial interface cable.

2. When considering the exact placement of a radio modem and/or its antenna, the following

points must be taken into account to guarantee optimal results:

 The antenna should be installed in open space as far as possible from any possible

sources of interference

 The radio modem should not be installed onto a strongly vibrating surface

 The radio modem should be installed in such a way as to minimise exposure to direct

sunlight.

3. To ensure reliable operation the voltage output of the power supply used must be stable enough

and the current capability of the power supply must be sufficient.

4. The antenna must be installed according to instructions.

Serial interface settings between the radio modem and the terminal unit must correspond to each

other.

6. All radio modems in the same system must be configured using equal radio settings (radio

frequency, channel spacing, compatibility, forward error correction and data field length).
