OPERATION

Before switching PA on, make sure that amplifier is grounded, antenna or dummy load
is connected, and line cord is putted to the outlet. Be sure you selected AC input by 7.1.
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.
We do not recommend to change antenna output during a transmission.
When you decide to have a short operating break, place the amplifier to the standby mode
rather than switch it off.
