Switching the tube headphone amplifier off
▷ Open the glass cover of the storage box (see page 39) if necessary.
1. Telescope the headband, place the headphones in the headphone com-
partment and carefully roll up the cable so that it ts completely into the
storage box.
2. Press the on/off button.
Or:
▷ Press the button on the remote control.
The status LED starts pulsing. The glass cover of the headphone storage box
closes. The amplier tubes and the operating elements retract to the “off”
position. Once the switch-off procedure is completed, the status LED lights up
red. The HE 1 is switched off (standby).
If, during switch-off of the HE 1 and closing of the glass cover, the cable
leaves the storage box or the travel of the glass cover is blocked, the
glass cover remains ajar so that e.g. the cable does not get clamped.
If you want to accelerate the switch-off process, press the on/off button
for 2 seconds when switching the amplier off.
To disconnect the HE 1 from the power supply system:
▷ Set the power switch to OFF to switch the HE 1 off.
▷ Unplug the power plug from the wall socket.
▷ Push and hold the red safety pin on the power plug and pull the power plug
from the IEC mains socket.
