OPERATION
Before switching PA on, make sure that amplifier is grounded, antenna or dummy load is
connected, and line cord is plugged into the outlet. Be sure you have selected the proper AC
input TAP (Sect 7.1)
Do not turn PA on for at least 2 hours after unpacking and located in its operating location.
Especially when amplifier is moved from a cold place to a warm one as condensation may
develop. This condition could result in damage to the high voltage circuits.
We do not recommend changing antennas during a transmission. (Hot switching)
When you decide to have a short operating break, we recommend placing the amplifier to the
standby mode rather than switch it off.
