3. Installation Options

The ISFM23 interrupts the incoming antenna signal when in use, to deliver the cleanest
audio possible from your device. To regain standard FM operation without interruption,
simply pause the Android device, iPod, iPhone or iPad, and approximately 8 seconds later
the full FM band will be accessible. There is also a power on/off/auto option in the TranzIt
BLU app. If manual power on/off control of the ISFM23 is desired, disconnect the "loop plug",
and plug the "optional toggle switch" into the power harness, in its place. This will allow the
user to turn the ISFM23 on or off at any time.
