On/Off and Volume Knob
Turns unit on or off and controls headphone audio level. When the IFBR1B is
first turned on, the firmware version will display briefly.
Battery Status LED
When the battery status LED glows green, the batteries are good. The color
changes to red at a midpoint during the runtime. When the LED begins to
blink red, only a few minutes remain.
The exact point at which the LED turns red will vary with battery brand and
condition, temperature and power consumption. The LED is intended to sim-
ply catch your attention, not to be an exact indicator of remaining time.
NOTE: The LCD will also alert when the battery is critically low.
RF Link LED
When a valid RF signal from a transmitter is received, this LED will light up
blue.
Headphone Output
A 3.5 mm mini phone jack accommodates a standard mono or stereo type
3.5 mm plug. The unit will drive low or high impedance earphones. The jack is
also the receiver antenna input with the earphone cord acting as the antenna.
The cord length is not critical but must be at least 6 inches minimum.
USB Port
Firmware updates via Wireless Designer are made easy with the USB port in
the battery compartment.
