Product: Wireless Microphone
Model: SNT-800
Profile
Welcome to our company! we
profe ssio nally produ ce UHF with
2 0 0 -c ha nn el f u n c ti on w i r el es s
microphone. They are adopted multi-
channel synthetic technology of DPLL
(digi ta l pha se -lock ed lo op ), 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

Situation Solution
No voice; (si tuation: the receiv ing machine
RF display ca n not come on)
Chec k the trans mitter a nd the rece iving ma chine, se e
whether it is on the pl ay of "ON"
Chec k whethe r the "nega tivre" a nd the "pos itive" p ole
of the batter y is confusi ng.
Check the con necting sol tion of the rece iving machineu
and the aeria l.
Make su re that the re is no block b etwee the a erial and
the transm itter.
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 pla ce.
Check whether the connecting between the loudspeakers
of the receiv ing machine are nomal.
Check whet her the power of the transmi tter 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 whet her the battery is tight eno ugh.
Elimina te the RF source of the disturb ance rearby.
Chec k the connec ting situ otion, if us ing githa r or other
mascial in sturment.
If both of the trans mitters are using the sam e frequency,
check it and clos e one lof them.
Maybe thesignal is too infirmnes s, adjust the place of the
antenna mo re it as near the transmitte r as possibl e.
Replace ot her channel.
There is some noise, after closing the
transmitter.
Adjust th e sensitivit y button of the trans mitter; the "SQ"
button.
Elimina te source of noise of RF.
Adju st the pla ce of the rec eiving m achine o r the plac e
of the antenn a over again
Can not open the transmitter
Change the ba ttery of the transmitt er.
While the showplace is moving. the voice from
the transmitter may get lost sometimes.
Adjust t he sensitivit y button of the tran smitter; the "SQ "
button.
Loca te the rec eiving m achine ov er again a nd hare the
"on-sho w" experiment, obs erre the RF display.
If you fi nd some voic e lost, tag th e point and av oid this
point when pe rforming.
Operation method and attentions
-1 2-
Operation method:
1.Con nect the au dio syst em well;
2. Set the volu me of the receiving machine and the louds peaker to mix;
3.Turn on the power of the audi o system from backing stage to backward stage;
4.Trun on the power of the tran smitter;
5. Adjust the audio effect of the audio system: firstly, adjust the volume of the receiving
mac hi ne t o th e mi ddle point, t ur n on t he m icrophone, ta lk d ir ec tl y forward the
microphone, fit the volume second ly, adjust the tone, volume contr oller carefully
and make the voice clea r, the volume suit abl e. Hdd the phone an d hare the "on
show" proless;
6. If the wir eless rece ivin g machine sys tem has some pro blem s. Please ref erence
this funcati on hare troubleshooting and solve the problem. If the problem is not in
the troubleshooting. Please onse the profe ssional 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 re ceiving machine sys tem ca n fill 200 micr oph one at th e same ti me, an d it
could not disturb each other. If need to be adjusted different channels by professional.
5. When some wire less sy stems are used at the same ti me, ple as take attention to
the setting of "SQ" of the receiving machine. The lower the sensitive is the shorter
the capa city of distu rbance cou d be ! It is better that th e transmit ph one is short.l
It can save the electron ic and decr ease the jamming at the same time.
