How to Transmit Audio
- Insert 2 AA batteries into Battery Holder. A red LED on the circuit board will light up.
- The Transmitter automatically tunes itself to 91.1 FM. To tune the ExiTrip higher, push the toggle switch to the right (away from the microcontroller). The light on the circuit board will blink while you are tuning the transmitter. Note that there is no display to tell you what station you are on. Instead, you can estimate this by counting the number of times the light flashes. Each flash represents 1/10th of a megahertz.. so 91.1, 91.2, 91.3 etc
- To input audio into the tranmitter, plug the 1/8th inch jack into any female mono or stereo 1/8th inch source. Make sure the volume on the audio source is set to an appropriate level, as clipping may occur at high volumes.
- Tune an FM radio reciever to a station that is mostly static. Note the station you are on. Now, using the toggle switch on the ExiTrip and counting the pulses of light, tune the transmitter to the station you have your radio set to. You should hear whatever audio you have going into the ExiTrip. If there is no input, you will hear silence instead of static.
- To power off the ExiTrip, simple push in on the Toggle Switch. The light will turn off. This will allow the transmitter to stay on the last station you tuned it to. To reset the ExiTrip to 91.1, remove the batteries from the battery pack.
