CHECKLIST B (Paragon4)
General Check out (part1 of 2)
Paragon4 units are set and characterized at the factory to optimize performances.
It is not recommended to try readjusting units unless it is really required.
Misadjusting a unit may result in significant performance losses.
The proposed adjustments in the "IF NOT?" column below, should be tried ONLY if system data performance degra-
dation is noticed combined with out-of-tolerance items.

(unless unit has been set a lower value). Note that readings less than 100 watts for UHF or 70 watts for the 700 and
800 MHz models, may be due to losses in cables used for testing. Check also your wattmeter frequency calibration
curve. Do not be too ready to condemn the transmitter or the RF feedline & antenna installation.
