Optimal input level is reached when the audio level at the receiver end
is equal to the level of a standard FM broadcast station. To obtain this
result it is mandatory to compress the audio input signal (between
your audio source output and the inputs of the MS-100). The over
modulation LED on the front panel shall never or rarely lite up.The
level has to be adjusted in a maner to avoid over modulation.

MAINTENANCE AND ALIGNMENT
A) Maintenance
No maintenance is required to keep the transmitter in top operating
condition. If an external cleaning appears necessary, use a soft, damp
cloth and mild soap only.
B) Frequency selection
The transmitting frequency is user programmable via a 10 bit dip
switch on the rear panel.If a change of frequency is required,folow
this simple step.
1) from the «bits switch» codes table, on the next pages, select the
appropriate «bits switch» code for your chosen frequency and set
the «bit switches» accordingly.
NOTES: 1) The frequency range of the MS-100 is 88.1 to 107.5mhz.
2) If your application requires more than one MS-100,it is
mandatory to leave some space between the two
choosen frequencies in a maner to avoid channel
scrambling or
intermodulation products.Ex; If the first choosen is
88.5mhz, then the second choosen frequency shall be
89.1mhz. The choosen frequencies shall not interfere
with local FM broadcast stations. If you intend to use
more
than two MS-100 in the same restricted area,Decade
company offers a free assistance service that will guide
you thru the steps of multiple frequencies setup.Please
call our service dept at: 1-819-563-4323. Hours are
8.30 AM to 5.00 PM, eastern time.
