equipment to ensure your interest in maintenance and service.

2. Product warranty, starting on the purchase date indicated on “warranty label”, will
last for one year; if the equipment does not have “warranty label”, the warranty
period is 15 months from the manufacturing date. If a microphone is broken but
not sent back with the equipment, the warranty period is 15 months from the
manufacturing date of the microphone.

3. Within the warranty period, if the equipment is broken under normal use as
instructed in manual, please contact the original selling store for repair.

4. When the product is returned for repair, to facilitate proper determination of
cause of malfunction and of whether repair fee is needed, please ship back the
equipment and microphone together.

except for the following conditions that parts and repair may be charged:
a.Damages due to natural disaster or irresistible outside forces.
b.Damages due to drop, water, moisture, corrosion, foreign objects, missing

components.

c.The warranty does not cover consumable parts. (such as microphone capsule,

ball grille etc.)

d.Those without “warranty label” on equipment or with “warranty label” being

damaged and failing to identify warranty period.

6. Please keep the warranty properly. No replacement will be made if the warranty
is missing.

5-1 How to connect the receiver

1. Connect the audio output of receiver to mixer or amplier

1.1 ：

(1) The XLR output jack or 6.3mm unbalance output jack can be selected

individually to connect the AF output to a mixer or amplier for volume

control.

(2) Switch the “Mixed” on the back to ON. This allows to mix the RX1 and RX2

signals to RX1’s 6.3mm non-balance output jack and then to a mixer or

amplier for volume control.

2. Connect the power

2.1. Connect the AC/DC adapter:

Check that the DC current and voltage ratings of the adapter match the

label on the unit. Connect the DC terminal to the “DC input” port on the unit,

and the AC end to an AC socket.

2.2. Set the parameters:

Turn the power on and set the parameters of receiver according to the

setting instructions.

Caution! Secure the power cable on the fastening hook of anti-pulling clip in
order to prevent the power cable from falling.

Hi

The Mute button on the hand-held unit also triggers the power-on. That’s why the

unit is on as soon as the batteries are replaced. Therefore, if you do not wish to turn on

after changing the batteries, keep the Mute switch on mute.

1. Unscrew the outer tube of the transmitter (Figure 1).

2. Place 2 AA batteries in the battery holder while make sure they are in the correct
polarities (Figure 2).

3. Screw the outer tube on (Figure 3).

4. To turn the unit on:

a. Push the power button to turn on (Figure 4a), or

b. Push the Mute switch up also to turn the unit on (Figure 4b).

5. Set the transmitter parameters according to the instructions.

3. Slide the battery holder cover upwards to close (Figure 3)

4. According to the type of microphone, insert the 4-pin mini XLR jack in MIC IN to

complete the installation (Figure 4).

5. Push the Power button to turn the unit on (Figure 5).

Pairing

Once the parameters are set, push the “ ” button and the
digital pairing data will be sent to the transmitter via ultrasonic transmitter
for parameter synchronization. The indicator will ash rapidly while the data
are being transmitted. When the synchronization is completed, the receiver
will receive the corresponding data and the indicator will stop ashing. If
the signal is not received for a certain period of time, the indicator will ash
slowly to inform pairing failure (the slowly ashing indicator can be reset by
pushing any button).

Note: The best pairing distance is 10~60cm, ±30º.

-30 +30

10~60cm

Note2: Only one Microphone can be synchronized at a time. When RX1 is synchronized, RX2

cannot be synchronized. RX2 must wait until RX1 is disconnected from synchronization.

Others

The LCD screen will display the Transmitter Battery Level simultaneously. If the Battery Level

≦ 2V, the battery’s outer frame will ash and the backlight will become Red as a warning.
