3. FIRST POWER-ON, CONTROL SYSTEM, AND INITIAL CHECK
NOTICE
Do not turn the amplifier on for at least 2 hours after unpacking it in the room where it
will be used. Pay particular attention when you move it from a very cold into a warm
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).
After following all instructions in Section 2 INSTALLATION, check whether the rear panel mains rocker switch
is turned OFF (see Figure 2-2 Rear panel - Connections, Pos. (3)). Then insert amplifier's mains plug into the
wall outlet prepared for it. The amplifier remains switched off.

3.1. Low Energy STANDBY Mode of the Power Supply
Now you can turn on the mains rocker switch (see Figure 2-2 Rear panel - Connections, Pos. (3)). This will
activate only the low-energy STANDBY mode of the amplifier power supply and the red LED above the front
panel POWER button will light up (see Figure 3-1 Front panel - Controls and Readouts, Pos. (b)), while the main
power supply is still off and the display is dark.
