CAUTIONS:
1. Some wireless microphone systems require a license. This depends on the fre
quency 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 working 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
AUTHORIZATION FROM GEMINI WILL VOID YOUR WARRANTY.
FCC RULES AND REGULATIONS:
This device complies with part 15 of the FCC rules. Operation is subject
to the following two conditions: (1)This device may not cause harmful
interference and (2) This device must accept any interference received,
including interference that may cause undesired operation.
Notice: The changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority to
operate the equipment. Important note, to comply with the FCC RF
exposure compliance requirements, no change to the antenna or the device is
permitted. Any change to the antenna or the device could result in the device
exceeding the RF exposure requirements and void user's authority to operate
the device.
UF WIRELESS SYSTEMS:
The UF wireless systems are high quality audio products that provide
systems available all operate with UHF high band frequencies.
Frequency ranges: USA: 682-698 MHz, Europe 854-865 MHz.

WIRELESS NOTES:

• 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:

UF RECEIVERS:
These stationary receivers are for use with our 64-channel selectable
transmitters. The receiver operates in UHF band frequency with PLL
synthesized control. Powered by 12V DC.
(1) POWER BUTTON: Push the POWER button to turn the receiver on & off.
(2) CHANNEL SELECTOR: 64 different selectable can be selected used by
rotating the selector(s) or knobs.
(2b) SET: Push the SET button to lock the selected group and channel.
(2c) GR/CH LED: These LED indicates the power is on, and display which
group & channel is on.
(3) POWER INDICATOR: The indicator LED lights when the receiver is ready to
operate.
(4) RF LEVEL INDICATORS: These LED lights to indicate that signal is being
received.
For the UF-1264 the RF LED show the diversity RF signal that is being used A or B.
For the UF-2064 the RF LEd display which MIc is being received MIC 1 or 2
(5) LEVEL CONTROL: Rotary controls adjust the receiver's output level
from the microphone to line level for matching the input sensitivity of the
mixer or amplifier.
(6) ANTENNA: Fixed-length UHF antenna permanently mounted either on
the front or on rear panel.
(7) DC OUT: Connect the supplied cable to the receiver and the microphone,
and it takes around 10 hours to charge.
(8) UNBALANCED OUTPUT: Unbalanced 1/4" mono jack audio output
provides unbalanced low-impedance output
(9) BALANCED OUTPUT: 3-pin XLR connector provides balanced low impedance
output
(10) SQUELCH ADJ: The squelch adjusts the output level to prevent from
the external noise. Setting the squelch too high will reduce the range of
the system. Set the squelch to minimum before turning the receiver on.
(11) DC IN: Input connector for the supplied AC adapter.
FM-64 HANDHELD MICROPHONE:
The handheld microphone operates in UHF band frequency with PLL
synthesized control. UHF 64 preprogramed selectable frequencies to
avoid interference. Uni-directional dynamic or uni-directional electret
condenser capsules with different characters for various choices. Use
1.5V x 2 AA size rechargeable or regular batteries for low operating cost.
(1) GRILLE: Protects the microphone capsule and helps reduce breath
sounds and wind noise. The grille for the various microphone capsules
differ in appearance.
(2) LOW BATTERY LED: LED indicates battery status. Switching the power
to "ON", the LED flashing once indicates that the transmitter has
sufficient power. If the LED stays on, it indicates that the battery has
insufficient power and should be changed soon. If the status LED fails to
flash, the battery is either dead or not positioned correctly, and you
should correct the positioning or change the battery.
(3) ON/OFF SWITCH: Turns transmitter power on and off.
(4) BATTERY COMPARTMENT: Insert two AA batteries into the excellent
performance under most operating conditions. The different
compartment and make sure that the polarity of batteries is correct.
