Working with your transmitter:

-Remember your station is Radio Revolt 97.7fm
-Never use metal objects to enclose, repair, or adjust your transmitter
-Always use your transmitter with utmost care as they are easily damaged.
-When in use, it's best to leave not to touch or move your transmitter, so place it on a stable surface like a table or desk
-Allow transmitter 1-3 minutes to warm up after you turn it on
-Use your plastic tuning tool to adjust the transmitter to 97.7.  you should hear dead air (for microphone) or your CD (for line input)

Tuning in and hooking up:

-Advise your listeners to use a digitally-tuned radio
-Due to battery drain, temperature changes, and the like, your transmitter may drift from 97.7fm and require adjusting with your plastic tuning tool
-When moving between the microphone and line input (CD player), move the jumper
-Put external audio sources at mid volume to avoid over modulation (distortion and other bad stuff like splatter).  Donít go "in the red" on mixer
-Your Radio Revolt transmitter is mono; so use only the right or red cable for line input
-Your transmitter microphone is similar to a lapel or room mic, so your sound source (your mouth, stereo speaker) should ideally be about ____ feet away
-Never use a line input connector with intertwined red and white cables as it will damage your transmitter
-If you want to hook up a mixer to your transmitter, it's best to use one with a mono switch
-You can use your stereo as a mixer through the tape monitor output line

How  to make a receiving antenna:

Most FM stations have so much power that you seldom need a receiving antenna on your stereo; however, with a micropower Part-15 transmitter, your stereo might appreciate a power boost that could highly increase the quality of your reception.  This applies mainly to component systems, not the popular compact stereo systems.  You can make a simple receiving antenna with a piece of speaker wire.

-Get a speaker wire that is about 5 feet long
-Wrap a piece of electrical tape over about 3 feet of the wire
-Using the remaining untaped 2 feet, split the wire apart down the middle
-Strip the insulation from the end of the taped wire, just as you would to hook up a speaker
-Insert them into your receiver's antenna jack, similar to a speaker jack and usually marked with an antenna symbol and a ground symbol
-Orient the split wire in the same direction as your transmitter's antenna is oriented, i.e. vertically or horizontally.  Note that most high power stations have a horizontal orientation, so you may want to use a vertical orientation
