Operating Instructions
Stereo/Mono Selection
Transmitting music in stereo generally gives you the highest-quality listening
experience. However, you may get better FM-signal reception by changing the
transmission to mono. The TuneCast 3 transmits in stereo mode by default. We suggest
that you switch from stereo to mono transmission only if your car stereo is NOT receiving
a clear signal from the TuneCast 3, or if you are listening to mono recordings such as
audio books.
Press and hold the "Mono/Stereo" button located on the upper-left corner of the
TuneCast 3. The status-bar indicator will transition from stereo to mono or vice versa.
The TuneCast 3 display will return to normal operation where the current frequency is
shown along with the current mono or stereo setting represented by:
