• Before setting up, make sure that the transmitter and receiver are tuned
to the same frequency.
• Do not use two transmitters in the same frequency. Use good quality
batteries to avoid the damage resulting from a defective leaking battery.
• Turn the volume control on the receiver to adjust receiver output level to
match input level requirements of an audio mixer or amplifier.
• While checking sound, move the transmitter around the area where you
use the system to look for dead spots. If you find any dead spot, change
the receiver position. If it does not work, avoid such places.
• To avoid interference, do not put the receiver too near metal object and
avoid obstructions between transmitter and receiver.
• Avoid the interference from TV, radio, other wireless appliances and etc.
FUNCTION DESCRIPTIONS:
UZ-1128 & UZ-9128 RECEIVERS:
(1) HEADPHONE MONITOR VOLUME CONTROL: Rotate this knob to
control headphone volume level.
(2)HEADPHONE INPUT CONNECTOR: Plug headphone into this 1/4” jack
connector to monitor receiver audio.
NOTE: NUMBERS (3)-(11) APPLY TO BOTH UZ-1128 & UZ-9128 RECIEVERS.
(3)POWER: Pushes the receiver on and off.
(4)CHANNEL + BUTTON: Press this button to change channel forward.
(5)CHANNEL - BUTTON: Press this button to change channel backward.
(6)PROGRAMMABLE DISPLAY: Displays channel number, frequency and
volume level.
(7)RF LEVEL INDICATORS: Five LEDs per RF antenna channel glow to
indicate RF signal strength. The more LEDs that glow, the stronger the
received signal. If none of these LEDs glow, no signal is being received.
(8) AF LEVEL INDICATORS: Five LEDs glow to indicate audio signal
strength. Green indicates normal operation. RED indicates approaching
overload condition.
(9)VOLUME + BUTTON: Press this button to increase the receiver output
level to match the input sensitivity of an audio mixer or an amplifier.
(10) VOLUME - BUTTON: Press this button to decrease the receiver output
level to match the input sensitivity of an audio mixer or an amplifier.
(11) DC OUT: Connect the supplied cable to the receiver and the microphone,
and it takes around 10 hours to charge.
(12) ANTENNA INPUT CONNECTOR: TNC-type connectors provide
connection to the supplied antennas or to coaxial cable used with an
antenna divider, antenna boosters or remote antennas.
(13) ANTENNA: Fixed-length UHF antenna permanently mounted on rear panel.
NOTE: NUMBERS (14)-(17) APPLY TO BOTH UZ-1128 & UZ-9128 RECIEVERS.
(14) BALANCED OUTPUT: 3-pin XLR connector provides balanced low-
impedance output
(15) UNBALANCED OUTPUT: 1/4” phone jack provides unbalanced low-
impedance output
(16) SQUELCH: The squelch adjusts the output level to suppress the noise.
The higher squelch control, the lower the sensitivity of the receiver and
decrease the service area of the system. Set the squelch to minimum
before turning the receiver on.
(17) DC IN: Input connector for the supplied AC adapter.
To combine two receivers in a 19" standard rack by using 2 short L type plastic
racks (L2) and 2 metal connecting plates (C1).

CAUTIONS:
1. In the UK Some wireless microphone systems require a license. This
depends on the frequency of the system and the country in which it is
to be used. It is the responsibility of the user to establish if a license is
required. As a guide, for the UK and Europe, VHF radio microphones
between 173.800 and 175.000 MHz, or UHF microphones between 863
MHz and 865 MHz do not need a license. This is for microphones work
ing at normal power (10mW ERP hand-held or 50mW ERP if body
worn). All other use on alternative frequencies needs a license. More
information on this can be found at :www.jfmg.co.uk/jfmgecom/
default.aspx If in any doubt, users are advised to investigate the
licensing requirements for their region.
2. All operating instructions should be read before using this equipment.
3. To reduce the risk of electrical shock, do not open the unit. THERE ARE
NO USER REPLACEABLE PARTS INSIDE. Please refer servicing to a
qualified service technician.
4. Do not expose this unit to direct sunlight or to a heat source such as a
radiator or stove.
5. Dust, dirt and debris can interfere with the performance of this unit. Make
an effort to keep the unit away from dusty, dirty environments, and cover
the unit when it is not in use. Dust it regularly with a soft, clean brush.
6. When moving this equipment, it should be placed in its original carton
and packaging. This will reduce the risk of damage during transit.
7. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
8. DO NOT USE ANY SPRAY CLEANER OR LUBRICANT ON ANY
CONTROLS OR SWITCHES.
9. REMEMBER, ANY CHANGES MADE TO THE UNIT WITHOUT
