Smartuner LED Description (Applicable to all Smartuners)
Smartuner Built In Test Equipment Status LED Descriptions
This LED will light when the tuner has found an acceptable match. It will remain lit until conditions have changed which will cause the tuner to find a different match. (i.e. A new transmit frequency has been detected, or tuner has been reset.)
This LED shows the status of the antenna impedance. When lit, the impedance is 50 ohms or less. When off, the impedance is greater than 50 ohms.
This LED will light when the VSWR is greater than 2:1. It will extinguish when VSWR is less than 2:1.
This LED indicates the status of the antenna reactance. When lit, reactance is inductive. When off, reactance is capacitive.
This LED indicates the presence or lack of RF power from the radio. When transmitting, the LED will light to indicate RF is being detected. In receive, the LED should be extinguished.
All LEDs will blink on and off at a rate of 2Hz to indicate the tuner was not able to find a valid match.
Note that these status LEDs are usually used to aid a technician in diagnosing the status of the antenna system and should not be thought of as laboratory instruments. Also, LED's in some Smartuners have secondary functions. These functions are explained in their respective manuals. As the Smartuner tunes, the BITE(Built In Test Equipment) status will be continually updated from the CPU.
