USER GUIDE
Professional wireless microphone
Thankfulness on purchazing our products. Please
read this user guide carefully before using, just to
ensure the microphonecould be perfouned optimally
Product: Wireless Microphone
Model: SNT-800

Profile
Welcome to our company! we
professionally produce UHF with
2 0 0 - c h a n n e l f u n c t i o n w i r e l e s s
microphone. They are adopted multi-
channel synthetic technology of DPLL
(digital phase-locked loop), and
pilotone technology. Within 50-meter
frequency band, preset 200 channels,
and then utilize infrared to select
channel and the system may pair
every of them and set automatically.
In this case, any microphone in the
system wold match the channel of
the receivers in the system. Especially
suitable for the occasion with several
sets being used simultaneously.

Problem & solution
-13-
Situation Solution
No voice; (situation: the receiving machine
RF display can not come on)
Check the transmitter and the receiving machine, see
whether it is on the play of "ON"
Check whether the "negativre" and the "positive" pole
of the battery is confusing.
Check the connecting sol tion of the receiving machineu
and the aerial.
Make sure that there is no block betwee the aerial and
the transmitter.
No voice; (situation: RF display is nomal; AF
display is nomal)
Check whether the voice re knob of the receiving machine
is on the lowest place.
Check whether the connecting between the loudspeakers
of the receiving machine are nomal.
Check whether the power of the transmitter is open
Exchange the mike of the transmitter when it is necessary
No voice; (situation: RF display is nomal; AF
display is un-nomal)
Put through the transmitter, there is some noise
or some interruption noise in the receiving
signal
Check whether the battery is tight enough.
Eliminate the RF source of the disturbance rearby.
Check the connecting situotion, if using githar or other
mascial insturment.
If both of the transmitters are using the same frequency,
check it and close one lof them.
Maybe thesignal is too infirmness, adjust the place of the
antenna more it as near the transmitter as possible.
Replace other channel.
There is some noise, after closing the
transmitter.
Adjust the sensitivity button of the transmitter; the "SQ"
button.
Eliminate source of noise of RF.
Adjust the place of the receiving machine or the place
of the antenna over again
Can not open the transmitter Change the battery of the transmitter.
While the showplace is moving. the voice from
the transmitter may get lost sometimes.
Adjust the sensitivity button of the transmitter; the "SQ"
button.
Locate the receiving machine over again and hare the
"on-show" experiment, obserre the RF display.
If you find some voice lost, tag the point and avoid this
point when performing.

Operation method and attentions
-12-
Operation method:
1.Connect the audio system well;
2. Set the volume of the receiving machine and the loudspeaker to mix;
3.Turn on the power of the audio system from backing stage to backward stage;
4.Trun on the power of the transmitter;
5. Adjust the audio effect of the audio system: firstly, adjust the volume of the receiving
machine to the middle point, turn on the microphone, talk directly forward the
microphone, fit the volume secondly, adjust the tone, volume controller carefully
and make the voice clear, the volume suitable. Hdd the phone and hare the "on
show" proless;
6. If the wireless receiving machine system has some problems. Please reference
this funcation hare troubleshooting and solve the problem. If the problem is not in
the troubleshooting. Please onse the professional to sowe it or hegotiate with the
franchiser;
7. After using, please turn off the power of the transmitter, than turn off the power of
al l the owdio system from backing stage word backword stage.
Attentions:
1. The erect location of the antenna effect the leleption effect of the leceivting machine
directly, so take attention to the installation method. If is the most important principle
that keep the distance between the microphone and the leceiving machine shortest.
2. Avoid putting the receiving machine hear the computer or other equipment which
can produce RF signal.
3. Avod putting the receiving machine in the orlop of the DB, exclude the installation
antenna from distance.
4. This receiving machine system can fill 200 microphone at the same time, and it
could not disturb each other. If need to be adjusted different channels by professional.
5. When some wireless systems are used at the same time, pleas take attention to
the setting of "SQ" of the receiving machine. The lower the sensitive is the shorter
the capacity of disturbance cou d be! It is better that the transmit phone is short.l
It can save the electronic and decrease the jamming at the same time.
The are components in the wireless sound conducting system as below:
●One wireless dual-channel RF receiver.
two wireless microphones. there are from ways to choose (demonstrated by
"system configuration" below)
●
