CHIAYO ELECTRONICS C047 LTD,
FCC ID' CTNSM-216
Thank you very much for choosing the Chiayo belt—pack transmitter. For it to work,
you need to have acorrespondi ng Chi ayo Wireless receiverinthe same frequency.
Fourdit’ferenttransmitters ( seetablebelow) are sharingthis operating manual,please
go through it thoroughly before operation.

The basic operations of all the above transmitters are almost the same. However,
sometimes they use different connectors to suit different requirements.

Operating instruction
INSTALLATION OF BATTERIES
This transmitter uses 3 pieces of " AA ” size batteries (Alkaline battery is
recommended ). To install or remove the batteries, press the release buttons at the
edges of the transmitter to open or close the cover as illustrated ( Fig.2 ). When
installing the batteries with the cover open toward you, the cover might block your
hand. It isthus recommendedthatwhile inserting or removing the batteries you should
hold the transmitter in such a way that the cover open away fromyout(seeFig.3)
Installation of Belt-clip
This specially designed detachable belt-clip allows the user to wear the transmitter

Inputs. .
Depending on customer requirements, Lavalier / Headset microphone or instrument
inputs could be connected to the transmitter via the audio input connector. User is free
to choosethe various inputsources butis advised totake note that connector used must
be compatible to each other. Thepin configurations ofvarious connectors are as follow
(Fig.6 & 7 & 8).

Installation of cable restraint
To prevent contact noise caused by constant tension
applied to the connector,, a cable restraint is designed
such that tension is totally reduced when it is properly
used (see Fig.9 ).
When the audio cable go through the cable restraint, it
could prevent sweat from going diectly into the
electronic board via the connector. ThlS is another
advantage of the cable restraint.
channelselection
Channel selection is possible only for SM-216 / SM-816
plus transmitters. To change channel, please open the
battery cover and access the rotary switch to select
channel with a small screwdriver. (FigrlO‘

Input Level Gain Control Adjustment
Low impedance ( Lo-Z ) ” MT" & high impedance (Hi—Z) " GT" gain controls are
situated inside the transmitter as shown in Fig to, Gain controls are adjustment ports
that enable youto use microphones ofdifferi ng output levels and Guitarori nstruments
with Hi-Z output. To adjust microphone( Lo-z) inputlevels, turn the " MT" control and
to adjust the GLitar orinstrument (Hi-Z ) input, adjust the " GT” gain control to set the
transmitter's desired audio input level
Caution and tips on how to obtain the best results.
1.Before insertzng the batteries, please make sure that they aare inserted according to
thecorrcct polarity.
2.For PLL 16 frequencies agile version, before operation please make sure that the
corresponding receiver MUST have the same frequency group and channel number as
the transmitter,
3.For fixed frequency version, before operation please make sure that corresponding
receiver MUST have the same frequency as the transmitter.
4.Before making any channel change, please switch off the power supply. The
synthesized program works in such a way that achange ofchannel will only take place
after a power offand on action. Otherwise, the preyiosly selected frequency will stay
unchanged.
5.After making a channel change‘ please make sure that the corresponding change is
made on the matching receiver alsot To be exact, changes MUST be made at both the
transmitter and receiver.
6.The audiocableofM-ZOOandSM-216 also serve as antenna.Thelength ofthecableis
cut according to the specific frequency range, Do not alterthe length or mix around the
cable ofdifferent transmitters The use of wrong audio cable will affect the antenna
efficiency of the transmitter!
7.Useonlybrand new Alkalinebatteries. Do nctuse " general purpose "batteries. When
batteries are weak, replace the three batteries altogether at the same time. Do not le
and use new and old batteries together.
8.Positionthe receiver‘such‘thatithastheleastpossibleobstructionsbetweenitandthe
transmitter. Li VIC of Sight is best!
9.Thetransmitter andthe receiver should be as close as possiblebut nctlessthan 1 m.
lO.A receiver receive signals from two or more transmitters
simultaneously
Cannot
“Turn the transmitteroff when it is not in use. Remove the batteries ifit is not to be
used for a period of time.
