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 amplifier's rear panel mains
rocker switch is turned OFF (see Figure 2-3 | Amplifier 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 amplifier's mains rocker switch (see Figure 2-3 | Amplifier rear panel - Connections,
Pos. 3). This will activate only the low-energy STANDBY mode of the amplifier power supply and the red LED
on amplifier's front panel will light up (see Figure 3-1 | Amplifier and RCU Front panels - Controls and Readouts,
Pos. (a)), as well as the red LED on RCU's front panel will light up also (see Figure 3-1 | Amplifier and RCU
Front panels - Controls and Readouts, Pos. (b)), while the amplifier's main power supply is still off and the RCU
display is dark (see Figure 3-1 | Amplifier and RCU Front panels - Controls and Readouts, Pos. (c)).
