Troubleshoot missing radios
If radios are not visible in the RLX-IH Browser, try the following:
First, click the Scan button again. Scans are sent as broadcast messages,
which can be dropped in RF connections, requiring the user to scan again.
Second, make sure that the firewall is not activated on your PC. (This is most
common in Windows XP). Open the Network connections folder in your
Windows Control Panel, then open the Local Area Connection Properties
window and verify that the check box under Internet Connection Firewall is
not checked.
If the preceding approaches do not help, the PC running the RLX-IH Browser
and the radios are probably not connected to the same local network. Verify
your connections.
If you are in topological view, any unlinked radios may be at the bottom of the
window. Scroll down to see all radios. If you still cannot see radios with the
RLX-IH Browser, call technical support.

Improve signal quality
If you need to improve a radio’s signal quality, try the following steps:
Adjust the direction of the high-gain antennas.
Increase the height of the antenna’s placement.
Use higher-gain antennas or external preamplifiers.
Select a new location for the radio and/or its antenna.
Decrease the length of the antenna cable.
Determine and resolve sources of interfering electrical noise.
Add a repeater between radios that are not communicating.
