RMYNT20FP03BROADCAST TRANSMITTER

NT20 FREQUENCY TUNING PROCEDURE On top of unit you will find a small rectangular cut out that allows you to reach a rotary switch systems. This device has been conceived to make frequency changes quick and easy. As shown in the figure there are 4 rotary switches, each one has a specific function. The first one, from top to bottom, is to set the MHz x 10 (ie: 91 MHz = 9; 100 MHz = A) The second one sets the MHz x 1 (ie: for 91 MHz you would need to set this switch on 1) The third one sets the KHz x 100 (ie: for 91.5 MHz this switch would be set on 5) The fourth one sets the KHz x 10 –usually left on 0. Here are some examples to better understand the procedure: If you need to program a frequency of 98.1 MHz, these are the settings: 1) Set first switch on number 9 2) Set second switch on 8 3) Set third switch on 1 4) Leave fourth switch on 0 If you need to program a frequency of 102.7 Mhz, you would do the following: 1) Set first switch on A (because this is the symbol that equals 10) 2) Set second switch on 2 3) Set third switch on 7 4) Leave fourth switch on 0 If you would like you can cover the cut out with a sticker once you have set your frequency.

Compliance with this requirement will be deemed to show occupied bandwidth to be 240kHz or less. Any emission appearing on the frequency removed from the carrier by more than 240 kHz and up to and including 600 kHz must be attenuated at least 35 dB below the level of the un- modulated carrier. Any emission appearing on the frequency removed from the carrier by more than 600 kHz must be attenuated at least 43 + 10 Log(P) dB below the level of the un-modulated carrier, or 80 dB, whichever is the lesser attenuation.
