TMO mode parameters
If the TMO mode is configured, at least one scan range for the lookup of base stations
of the TETRA network must be configured. Here, the value of the first (lowest) scan
frequency must be inserted. Alternatively if no frequency information is available, a
TETRA “Channel” can be selected at “Select input” and the number of the first channel
can be inserted in combination with the networks offset value. The range of scanned
channels can be varied up to a maximum value of 400.
To apply the changes the button “Apply” has to be pushed. Following a button appears
underneath to restart the device. After the restart the device reprograms the internal
TETRA modem with the new parameters. This can be seen when the numbered LEDs in
the RF display are toggled from the right to the left.
Next the modem starts to log in the network. The RF display runs from the right to the
left again. This means that it is essential to observe the LED movement at least twice
before the device is registered in the network using the new parameters.
When registered the RF display shows the field strength of the device. Otherwise it
starts consecutive tries to access the network.
