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.
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.
WARNING: changes or modifications not expressly
approved by the party responsible for compliance could
void the user's authority to operate the equipment.
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.
b: Ten channels can be used simultaneously at most. They are respectively
CH0, CH1, CH3, CH4, CH6, CH7, CH8, CH9, CHE, CHF. The rest 6 channels
are available for customer's choice.

4. OPERATION
TABLE OF CONTENTS
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.
- SQUELCH CONTROL
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.

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.
