CAUTION
Do not turn PA on for at least 2 hours after unpacking it and locating in its operating
location. Especially when amplifier is moved from a cold place to a warm one because
not visible condensation may develop, and this could result in damage to the high
voltage circuits of the PA.
CAUTION
Never try to change antenna output during a transmission to avoid warranty loss.
NOTE
When you decide to have a short operating break, place the amplifier in the standby mode
rather than switch it off.
5.1. Operation Elements
There is couple of operational elements accessible or visible on the front panel.
BAND- Band selector switch (not in the picture).
TUNE - Anode capacitor for tuning, tuning of higher frequencies to "0",
lower frequencies to „100“.
LOAD - Output capacitor tunes antenna load resistance to amplifier.
Capacity is low at „100“ and high at "0" on the scale.
OFF - You switch off the amplifier by pressing this button.
ON - You switch on the amplifier by pressing this button.
After 3min of warm-up delay, the amplifier will be ready for operation.
OPR/STBY „OPERATE“ sets the amplifier ready for transmit operation.
