Tips To Make It Work Better
Location
Optimum placement for the FM Transmitter is usually away from other
electronic devices and objects. The higher the transmitter is located the
better. The transmitter can be helped by placing it on something that will
act as a ground plane like a metal filing cabinet or a refrigerator. Try
moving it around for best performance.
Range is subject to many variables, including obstructions such as walls
and FM signal overload in your area. The range of the FM Transmitter is
between 30 and 75 feet, line of sight with no obstructions.
Auto Shut-Off
The “Auto Shut-Off” will not work until you activate it. Press and hold the
power button down, the words Auto-OFF will appear on the display and
the transmitter will start to cycle through the available shut-off times.
You can choose from 1, 2, 3, 4 or 8 HR shut-off times. If you miss the
time you want, just keep holding the button down and it will start over.
To select your time, let go of the button. Turning the power off and back
on clears the auto shut-off.
