Setup

Connect the transceiver to the RF input and the antenna feed line to the antenna port. Begin with the radio at minimum output power in a supported mode, initiate tuning, and increase power only after a stable match is confirmed.

RF note: Do not exceed the mode- and frequency-specific power limits. A tuner changes the impedance seen by the radio; it does not correct an unsafe, damaged or unsuitable antenna system.
