LED’s
Yellow = Carrier Detect, indicates a carrier
frequency has been detected.
Green = Power applied to Loader, see below.
Red = Transmit, indicates the radio is
transmitting.
Radios are factory configured with LED’s
enabled. When the radio is connected to
power, the Green power LED will stay on
unless the radio is connected to an RF95A and
a datalogger. When using the RF95A and
datalogger, the green LED will start flashing
after 45 seconds. A flashing green LED
indicates the RF300 is in sleep mode.
LED’s can be Enable/Disabled via the JDT
Software
