Installing the Batteries
IFBR1C functions with two (2) AA batteries (+1.5 VDC
each); alkaline, lithium, or NiMH rechargeables (sup-
plied). Pinch the buttons on each side of the battery
door, and pull the door toward you to open. Install the
batteries according to the polarity diagram. Select either
“primary” (non-rechargable) or “NiMH” (rechargeable)
via the slide switch next to the USB connector. Press
the battery door closed until you hear the retaining
clasps snap.
WARNING! Do NOT select (NiMH) rechargeable
if you are using Lithium or Alkaline batteries;
these are primary cells and can be damaged
by enabling recharging. Use the NiMH only
with rechargeable Nickel Metal Hydride NiMH)
batteries.
Battery Setup
Use the arrows to select A for alkaline, L for lithium. The
default is alkaline.

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 simply 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 the IFBlue Updater are made
easy with the USB port in the battery compartment.
