8.1.1.4 Hand-Held RF Channel Scanner
A scanner can be used to detect the RF emissions of the radio and display the
frequency, thus verifying the operating frequency. An example of an
inexpensive scanner is listed below.

8.2 Troubleshooting
A dual color LED on the RF320-series radios provides a visual indication of
the radio’s operational status. TABLE 8-1 describes the meaning of the LED
status indications.
TABLE 8-1. LED Status Indications
LED Radio Status
Bright Red Transmitter is active.
Bright Green Carrier present on channel.
Bright Blinking Red The PLL is unlocked, PA is over heated, or TX
regulator voltage is not present while attempting to
transmit.
Dull Blinking Red The PLL is unlocked or TX regulator remains on in
receive mode.
If a fault in the radio is indicted by the LED, or a degradation of performance is
evident or suspected, the radio troubleshooting guide of TABLE 8-2 in
conjunction with the radio functional checks should be followed to ascertain
the proper corrective action. The probable cause and corrective action listed in
TABLE 8-2 is predicated on the following assumptions:
• The programmable parameters of the radio have not been altered from
the as-shipped settings.
• The radio modem is properly configured and the communication link
between the modem and the datalogger or the datalogger support
software is fully functional.
• The remote site that the radio is attempting to communicate with is
fully functional.
