1. Important Caution
2. Features
Make all connections before plugging the unit into an AC power outlet.•
Do not leave the devices in a place neither with high temperature nor high humidity.•
Do not headle the power cord with hands!•
Keep the devices away from re and heat sources.•
e systems operate in the UHF band, that there is less interference than the VHF band.•
Equipped with S.A.W. lter for eectively reducing the spurious RF interference content and•
present only focused incoming signal.
Built-in noise mute and squelch circuity mode can resist the interference validly.•
e tuned antennas are able to benet the optimum reception.•
e Anti-interference design makes the system available to work with every computer device.•

5. Preparing Procedures & Basic Operation
5-1 Receiver
(1) Audio Output Connector
Connect one end of the AF output cable to the AF output socket in the rear panel, then plug
another end to the “MIC IN” input socket of a mixer or amplier. (Step 1)
It is equipped with balanced XLR output and unbalanced Φ6.3mm output, choose the
proper way for use.
(2) Power output connector
Plug in one end of AC/DC adaptor cable to DC input socket in the rear panel of receiver, and
plug another end into an AC outlet. (Step 2)

(3) Turn the receiver on by pressing the Power buon on
the front panel
(4) Adjust the volume control to a proper level.

Using the baery charger of US-9030DC Pro
1. Push the charger’s tray and put 4 pcs of rechargeable baeries into the baery tray. Please
match the correct polarity (+ and -) , then return the tray for charging the baeries.
2. It is convenient to know the charging status via the LED indicator. e two red LED will
ash during charging and as soon as the baeries is fully charged, the two red LED will
light up.
Caution
To avoid baery leakage or explosion
(1) Remove baeries when the wireless microphones will not be used for a long time.
(2) When you need to replace the baeries, replace both baeries at the same time with new
ones.
(3) Don’t use dierent type of baeries together!

(1) Turning the transmier on/o
e on/o switch is located on the boom of the microphone.
(2) Inserting and changing the baery
1. Loosen the microphone head counter-clockwise. (Figure 1)
2. Hold on to both baery tray buons to release it. (Figure 2)
3. Insert 2 pieces of UM-3 1. 5 V baeries, remember to match
correct polarity. (step1 of Figure3)
4. Directly push the baery tray back. (step2 of Figure3)
5. Aim the connectors exactly for screwing on the microphone
head clockwise. (Figure 4)
(1) Loosen the baery cover and put the two 1.5V baeries into the baery tray.
(2) Aer puing into the baery, switch on the power on/o on the boom side of microphone.
