1. Install two antennas to the antenna socket A & B of the rear panel, the
direction between them should be adjusted about 90°.
Do not install in too firmly or it may damage your system’s
antenna output.
2. Insert the DC power to the rear panel of your system.
Only use a DC 13~15v DC power, if you use any other power
voltage other than DC 13~15v you may damage the system. Your
warranty may be terminated if you damage it like this.
3. Turn on the power button that the LCD screen will be on.
4. Adjust the receiver’s status to your liking.
5. Turn off power the LCD screen will automatically shut off.

These 14 frequencies are default set by the manufacturer.
Therefore, you cannot change them.
Each wireless system has two built-in UHF frequencies, so these 14 different frequencies are set into 7 groups from A to G. If you use more than two frequencies (for channel), you may purchase a different group of frequencies. For example, if you have the group A for frequency, then you need to purchase the group other than
A (i.e. from B to G). Otherwise, the frequencies will be interrupted.
However, if you find some interruptions in your wireless system within 200 feet, there is possibility that you may use the same frequency in your area.
Therefore, you need to change the frequency in your wireless system, or you may need to upgrade your wireless system. For upgrading your wireless system, we recommend you to purchase the VM-92U because it has
32 different UHF frequencies for selection.

HOW TO CONNECT AUDIO OUT
There are three different connectors as shown in the following diagram:
• Connector A is a mixed audio output (Channel A and Channel B)
• Connector B is a channel B XLR-balanced audio out (Group B Mic.)
• Connector C is a channel A XLR-balanced audio out (Group A Mic.)
NOTE
Connector A is an unbalanced audio signal. If you connect A to the mixer or amplifier, then both MIC. A and MIC. B will have the same effect.
Connector B is a balanced XLR audio signal. If you connect B to the mixer or amplifier, then you can control the microphone effect on MIC. B only.
Connector C (Balanced A) is a balanced XLR audio signal. If you connect A to the mixer or amplifier, then you can control the microphone effect on MIC.
A only.

To Register Your Warranty
Please fill out the warranty card that came with your unit, download or submit online warranty form. However, we need the invoice for your purchase in order to process this warranty. You may also register your warranty online.
Please visit our website at www.bettermusicbuilder.com.
PRECAUTION
1. If you want to use more than one of this system, please select the work frequency
(or signal channel) carefully so as to avoid disturbing.
2. The input power voltage of the receiver is 120V (±10%). If it is too low or too
high, it will affect the work of the machine.
3. When you install the battery, you must not reverse the electrode or you will
damage the machine.
4. When using the sensitivity solution function, the numerical value you select must be
at least 15dB. Otherwise, if the distance is too far, its signal-to noise radio goes
worse.
RISK OF ELECTRIC SHOCK
DO NOT OPEN
Caution: To reduce the risk of electrical shock, do not remove the cover (or back). No user serviceable parts inside: refer servicing to qualified personnel.
Warning: To reduce the risk of fire or electrical shock, do not expose this appliance to rain or moisture.
This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure voltage that may be sufficient to constitute a risk of shock.
This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Read the manual.
