Radio Troubleshooting

Symptom

Problem

Solution

The radio does not show up on the
display

The radio does not have power

Check the power/Ethernet cables,
ensure connections are tight. Radio
only operates on switched power.
LED will illuminate green when power
is properly connected.

Configuration

Check Connection Status on page
1 of diagnostics. Status should be
Enabled when radio is powered and
joined to a network. Ensure display
software is updated.

The radio does not show up on
OTHER displays

Network set up incorrectly

All radios must have an IDENTICAL
Network Name and Channel in order
to communicate with each other.

The radio exhibits decreased range Faulty antenna path

Ensure that coax cable from the radio
to antenna is in good shape, and that
antenna is securely fastened. Ensure
antenna is not broken.

Low power availability

Ensure Ethernet cable is securely
attached to the radio. Make sure the
radio LED is green.

Interference from outside sources

There may be an outside system
interfering with the signal. Try
switching to a different Channel (all
nodes in network must switch in order
to keep communicating).

Obstruction in path between vehicles

The MCR is a line-of-sight system.
Any obstructions (trees, hills, parts
of the vehicle, etc) obstructing the
antennas from having a direct line of
sight will decrease the range of the
system.

Signal Strength shows zero bars

Indirect nodes

The MCR is a line-of-sight system.
The MCR also utilizes advanced
networking features to communicate
with nodes that it cannot directly see,
but can see through other MCR nodes
in the network. In this case Zero Bars
of Signal does not mean there is a
problem.

Faulty antenna path

Check antenna to ensure a solid
connection.
