7 Operation
Prior to operating the system, place the wind-
shield (12) on the microphone (11) (two wind-
shields are provided) and, as a precaution, turn
the volume control VOL (19) on the receiver to
the left stop "MIN "
1) To switch on the receiver, engage the button
POWER (15); the LED of the button will light
up The outputs (21, 22) will be muted as
long as no radio signal of sufficient strength
is received
2) Make sure that the transmitter is switched
off First, set the transmission channel on the
receiver: Using one of the two tools provided
(13), turn the rotary switch CH (16) in such
a way that the notch points to the channel
CH
number
The reception LED indicator RF (17) must not
light up If it lights up, interference or signals
of other radio transmitters are being received
In this case, select a different channel
3) Set the transmitter to the same channel ad-
justed on the receiver: Using one of the two
tools provided (13), turn the rotary switch
CH (8) in such a way that its flat side points
to the channel number The outer ring of num-
bers applies
5
CH
Note: When multiple systems US-8001DBGY/ 5 are
simultaneously used at the place of application, a
different channel must be adjusted for each system
The number of channels that can be used simulta-
neously without mutual interference depends on
the conditions at the place of application (max
4 channels)
4) Use the button ON / OFF/ MUTE (2) to switch
on the transmitter; the power indicator (3) will

light up When it lights up in red, replace the
battery To mute (the power LED indicator will
start flashing) and to unmute the transmitter,
briefly press the button again
When the transmitter is switched on and
not muted, the reception LED indicator RF (17)
on the receiver must light up: either in red
or in green, depending on the antenna that
receives a signal of higher strength If the re-
ception LED indicator does not light up, check
the following items:
a Is the battery of the transmitter discharged?
b Have the transmitter and the receiver been
adjusted to the same channel?
c Is the distance between the transmitter and
the receiver too long?
d Is the reception disturbed by objects in the
transmission path?
Make sure to keep the transmitter and the
receiver at a minimum distance of 50 cm
from metal objects and any other sources
of interference (e g electric motors or
fluorescent lamps)
e Is the reception improved by turning the
antennas (20)?
5) Put on the headband (9) and align the goose-
neck (10) in such a way that the microphone
is close to your mouth To adapt the head -
band to your head size, release the locking
nuts (5) and then adjust the head strap (7)
accordingly
6) Speak / Sing into the microphone; use the vol-
ume control VOL (19) to match the output
level of the receiver to the input of the sub-
sequent audio unit Regardless of the adjust-
ment of the control VOL, the audio signal LED
indicator AF (18) will light up in the rhythm of
the audio signal received
The volume of the audio signal received
can be readjusted by means of the control
GAIN (6): When the volume of the audio signal
is too high and the signal is distorted, turn
back the control When the volume of the
audio signal is too low, the signal-to-noise
ratio is poor; in this case, advance the control
accordingly Use one of the two tools provided
(13) to adjust the control
