is the powerport (in), which may be
connected with 230V or 115V alternating current
(AC) by use of standard three-pin plug (random
configuration). Before use, please check if the
voltage transfer switch (Figure 1)
⑪
is consistent
with the alternating current (AC). When the voltage
transfer switch is at 115V position, it can adapt to
110 - 120V/60HZ alternating current (AC); when the
voltage is at 230V position, it can adapt to
220-240V/50HZ alternating current (AC); the
switch’s factory setting is 230V (Note: only adjust
under professional guidance)

is the power switch and
volume knob. By clockwise rotation, turn
the power on, and by counterclockwise
rotation, turn the power off. After power
on, continue to rotate to the right to
increase the volume to an appropriate
location (the volume knob is normally
adjusted to around ten o'clock direction).
Due to the use of vacuum tube amplifier,
vacuum tube needs about 30 seconds for
warming up before normal operation.
Therefore, the radio speaker will make a
sound 30 seconds later. Note that the
volume can’t be turned to the maximum
during these moments.
