3. FIRST POWER-ON, CONTROL SYSTEM, AND INITIAL CHECK

Do not turn the amplifier on for at least 2 hours after unpacking it in the room where it

place - condensation is likely and this could result in damage to the high voltage circuits.
In such a case, wait at least 4 hours. A similar effect can occur after a rapid warming of
the operating room (for instance after switching on a powerful heater in a cold shack).
