5. TECHNICAL SPECIFICATIONS
IMPORTANT SAFETY INSTRUCTIONS
Read these instructions.
Keep these instructions.
Heed all warnings.
Only use attachments/accessories spec-
ified by the manufacturer.
Power Cord and Plug
Do not defeat the safety purpose of the
polarized or grounding type plug.
A polarized plug has two blades with
one wider than the other. A grounding
type plug has two blades and a third
grounding prong. The wide blade or the
third prong are provided for your safety.
If the provided plug does not fit into your
outlet, consult an electrician for replace-
ment of the obsolete outlet.
Protect the power cord from being walk-
ed on or pinched particularly at plugs,
convenience receptacles, and the point
where they exit from the apparatus.
Cleaning
When the apparatus needs a cleaning, you
can blow off dust from the apparatus with
a blower or clean with rag etc.
Don't use solvents such as benzol, alcohol,
or other fluids with very strong volatility and
flammability for cleaning the apparatus body.
Clean only with dry cloth.
Servicing
Refer all servicing to qualified personnel. To
reduce the risk of electric shock, do n ot perform
any servicing other than that contained in the
operating instructions unless you are qualified
to do so .
Servicing is required when the apparatus has
been damaged in any way ,such as power
supply cord or plug is damaged , liquid has
been spilled or objects have fallen into the
apparatus, the apparatus has been exposed
to rain or moisture, does not operate normally,
or has been dropped.
Follow all instructions.
instructions. Do not install near any heat
sources such as radiators, heat registers,
stoves, or other apparatus (including am-
plifiers) that produce heat. Do not block
any ventilation openings.
No naked flame sources, such as lighted
candles, should be placed on the apparatus.

4.3 OPERATING FREQUENCY MATCHES BETWEEN THE RECEIVER AND
THE TRANSMITTER
To make the operating frequency matched between the transmitter and the receiver,
adjust the transmitter and receiver manually with the adjusting bar for the same
frequency. Please refer to the following table for selecting frequency.
Caution: a: If several apparatus are used at the same time, the same frequency can not
be used for them.

4. OPERATION
4.1 FOR the UB-81R/81DV, PLL UHF DIVERSITY RECEIVER
- MANUALLY SELECTING FREQUENCY
With an adjusting bar, adjust the band selector to select the right frequency which matches
the frequency of transmitter.
- OUTPUT VOLUME CONTROL
It is used to control the output volume. Turn the knob clockwise and the output volume
increases. Turn the knob counter- clockwise and the output volume decreases.
The job of a squelch circuit is to reduce audible noise. It eliminates noise during
pauses in the audio signal by muting the receiver every time and the audio level
drops below a defined threshold. The squelch control on the receiver sets this
threshold. Use the squelch control with care! If the squelch threshold is too
high, the squelch will not only cut out noise but mute quiet audio signals as
well because the squelch responds to the detected voltage and cannot
distinguish between wanted signal and noise. Besides that, a too high squelch
threshold also decreases the usable range. The squelch range is 95.0dB~65.
0dB. Use an adjusting bar to adjust the squelch selector for a right squelch
threshold.
- SQUELCH CONTROL
4.2 FOR the UB-8H/8P SERIES TRANSMITTER
4.2.1 FREQUENCY SELECT
In practice, to effectively avoid the interference from any lighting equipment, Com-
puters, fax machines, etc nearby, It is usually advised to switch to another
frequency to get best performance.
The frequency range of this system is UHF, 740MHz ~ 769MHz, and it is divided into
16 frequency bands according to the country's EMC regulations; Each frequency band
can be manually adjusted with an adjusting bar. If you want to switch a frequency, you
have to turn off the unit, adjust frequency and then turn it on again.
4.2.2 BATTERY REPLACING AND CHARGING
Please be advised to use only one pair of AA 1.5V batteries for power supply.
Caution: Danger of explosion if battery is incorrectly replaced. Replace the batteries
only with the same or equivalent type.

1. INTRODUCTION
Thanks for purchasing the SHOW wireless microphone system. The UB-8H/8P/81R/81DV
Series is the delicately designed UHF, PLL synthesized system, with antenna built inside
the receiver for smart switching diversity control, the higher level RF signals maybe fed
into the system for greater reliability and coverage, therefore, the risks of breakdown
and interference are to be effectively reduced.
You can manually adjust the channel of the transmitter to match that of the receiver if
you know about the operating frequency of it.
Generally, the UB-8H/8P/81R/81DV series consists of
-UB-81DV, PLL UHF Diversity Receiver
-UB-8H, Handheld transmitter
-UB-8P series, Body Pack transmitter
UB-81DV, PLL UHF DIVERSITY RECEIVER
