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 or excessive humidity.
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.
5. Settings of the radio modem must correspond to settings of the terminal.
6. All radio modems in the same system must be configured using same settings (radio
frequency, channel spacing and data field length).
