When using any electronic product the following basic precautions should always be adhered to:
1. Read all the safety and installation instructions, explanations of graphic symbols and set-up / controls
before using any product.
2. This product must be earthed. In the unlikely event of malfunction or breakdown, grounding provides
a path of least resistance for an electric current, which reduces the risk of electric shock. This product
is equipped with a cord featuring an equipment-grounding conductor and a grounding plug. The plug
must be connected to an appropriate outlet that is properly installed and earthed in accordance with
all local codes and regulations.
DANGER: Improper connection of the equipment grounding conductor can result in a risk of electric
shock. Check with a qualified electrician or service professional if you are in doubt as to whether the
product is properly grounded. Do not modify the plug provided with the product. If the plug does not
fit the outlet, have a proper outlet installed by a qualified technician.
3. To reduce the risk of injury, close supervision is necessary when the product is used, especially
near children.
4. Do not use this product near water: eg. near a bathtub, sink, in a wet basement or near a swimming pool.
5. This product, either alone or in combination with an instrument and headphones or speakers, may be capable of
producing sound levels that could cause permanent hearing loss. Do not operate for a long period of time at a high
volume level, or at a level that is uncomfortable.
6. This product should be installed and used in a location that provides adequate ventilation.
7. This product should be located away from heat sources, such as radiators, heat registers, or other
products or circumstances that produce heat.
8. This product should be connected to a power supply only of the type described in the operating
instructions or as marked on the product.
9. The power supply cord of the product should be unplugged from the outlet when left unused for a long period of
time. When unplugging the power supply cord, do not pull on the cord but grasp it by the plug.
10. Care should be taken to ensure that objects and liquids do not enter the enclosure through any openings.
11. The product should be serviced by qualified service personnel when:
A. The power supply cord, or the plug, has been damaged.
B. Objects have fallen on, or liquid has been spilled into, the product.
C. The product has been exposed to rain or moisture.
D. The product has been dropped or damaged.
E. The product does not appear to be operating normally, or exhibits a marked change in performance
12. Do not attempt to service the product beyond what is described in the manual instructions. All other
servicing should be referred to qualified service personnel.
13. Do not place objects on the product, the power cord, or place it in a position where anyone could trip over, walk
on, or roll anything over it. Do not allow any part of the product to rest on, or be installed
over, power cords of any type. Improper installations of this type create the possibility of fire and a general safety
hazard.
WARNING
IMPORTANT NOTE: To reduce the risk related to the correct and normal use of the product, all Ashton products are
accurately tested in a safety laboratory. Do not modify the present unit, the safety standard and the instrument’s

3. Press the SET key until GROUP flickers.
Press or key to select suitable group number
(Diagram 1). Press the SET key again until MANU-
AL CHANNEL flickers. Press or key
to select the suitable channel. (Diagram 2)
NOTE: When multi-systems are in use, all systems
must be set to the same group number. Select an
exclusive channel for each system in the same group.
1. Take transmitter out of box. Screw the antenna into
A and B Jacks. Plug audio cable into channel XLR
output socket and connect other end into desired
speaker or other output source. Place all applicable
batteries into receivers.
2. Plug power cable into transmitter. Make sure
output source is powered on.
6. Indicates the working frequency. (Diagram 5)
1. Turn ON the transmitter, point the IR window
of receiver to the IR window of the transmitter.
2. Press the ASC key on the receiver. Keep the IR
window of the receiver pointed at the IR window
of the transmitter, then press the ASC key
of the transmitter.
3. Press the ASC key of the receiver, this will
broadcast the signal for 25 seconds - INFRARED
will flicker on the display. (Diagram 6)

the ASC key on the body pack, the transmitter
will broadcast the signal for 25 seconds.
This will pair the two devices.
5. The LCD of the transmitter will flicker when
IR connection is enabled, as will the IR symbol
on the LED.
NOTE: When establishing an IR connection between
the receiver and the transmitter, the distance
between them should not exceed 50cm. When more
than one system is in use, only one transmitter IR
window should be pointed to the receiver at any
given time.

TROUBLESHOOTING
PROBLEM LED STATUS SOLUTION
No sound or faint
sound
The LED of the transmitter is off Slide the transmitter’s power switch to ON. Make
sure battery terminals match transmitter terminals.
The LED of the receiver is off Make sure to attach the power adaptor to the DC
input in the back of the receiver and attach the
other end to a wall power socket. Check whether
the wall power socket and voltage supply is
normal.
The RF LED of the receiver
is illuminated
Turn up the volume of the receiver. Turn up the
gain of the transmitter. Check the cable connection
between the receiver and amplifier or between the
receiver and mixer.
The RF LED of the receiver
is off, but the LED of the
transmitter remains on
Put the receiver away from any metallic object,
check whether there is an obstruction between
the transmitter and receiver. Ensure that the
transmitter and the receiver are tuned to the same
frequency.
The battery life LED is flickering Replace the battery of transmitter.
Distortion of noise The LED display of the receiver
indicates the antenna is valid
Make sure the receiver is a reasonable distance
away from the RF generating equipment, such as
a CD player, computer and digital signal processor.
Change the frequency of the transmitter and
receiver. Turn down the gain of the transmitter.
Replace the battery
of the transmitter. Increase the bandwidth
of frequency when multi-systems are in use.
Distortion level
increases gradually
The battery life LED is flickering Replace the battery of the transmitter.
Sound level from the
receiver is different
from that of a cabled
guitar or microphone
Adjust transmitters gain and receivers volume
as necessary.

Many regions have strict management on the
frequency of the radio. This system provides
several bandwidth selections:
UA: 518 – 548MHz UB: 630– 660MHz
UC: 740 – 770MHz UD: 800 – 822MHz
UE: 838– 865MHz
The system presets multi-group and channel
to avoid RF interference. Adjust the channel
of the system when multi–use receivers are
in use. There are approximately 16 units of
receivers/transmitters in use in one bandwidth.
• Maintain a line of sight between the transmitter and
receiver.
• Keep the receiver more than 1m from the ground,
avoid placing it close to walls.
• Try to avoid setting up the wireless system around
appliances that cause interference,
such as TV, radio and other wireless appliances.
• Avoid placing the receiver near metal or RF generat-
ing equipment such as CD players,
computers & digital signal processors.
