IFBR1C Features
Link LED
On/Off and volume knob
Headphone output
Battery Status LED
On/Off and Volume Knob
Turns unit on or off and controls headphone audio level. When the IFBR1C is
first turned on, the firmware version will display briefly.
Battery Status LED
When the battery status LED glows green, the batteries are charged. The
color changes to red to warn that the batteries are low. 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 IFBlue Updater Utility are made easy with the USB port
in the battery compartment.

Basic Operation
Frequency Selection
Press the FREQ button once to select receiver frequency in MHz. The UP and
DOWN arrow buttons adjust the Frequency in 1 MHz steps. Press the FREQ
button again to select receiver frequency in kHz. The UP and DOWN arrow
buttons adjust the Frequency in 25 kHz steps (VHF: 175 kHz steps).
NOTE: Holding down the UP or DOWN arrow button, as opposed to a
quick press, will scroll through the frequency steps at an accelerated
pace.
IFBR1C functions with two (2) AA
batteries; alkaline, lithium, or NiMH
rechargeables (supplied). Pinch the
buttons on each side of the battery
door, and pull the door toward you
to open. Install the batteries with the
tip (positive) to the flat terminal and
the bottom (negative) on the spring
contacts. Select either “primary”
(non-rechargable) or “NiMH” (re-
chargeable) 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 NiMH (rechargeable) batteries.

2. Use UP and DOWN to choose the desired slot. When navigating among
the preset slots in this way, all slots are accessible, even the empty ones,
and the receiver’s tuning is not affected.
3. If the desired preset slot is occupied, you can reprogram by pressing
PRESET + DOWN to clear the slot.
4. Press FREQ to display the frequency, then use the UP and DOWN arrow
buttons to adjust the frequency in 1 Mhz steps.
5. Press PRESET again to return to the preset page. You should see the slot
you chose.

installing either Alkaline or NiMH batteries select the bat A setting and then
turn off the unit to save this option.
Below the Freq button ( button just left of the up-arrow) is a switch with a red
cap. This switch should be in the PRIMARY position for Lithium and Alkaline
batteries and should be in the NiMH position for rechargeable NiMH batteries.
This red capped switch, when in the NiMH position, engages the charging
contacts on the bottom of the unit, while this switch is in the PRIMARY posi-
tion the charging contacts are disengaged.
To recharge NiMH batteries, use the IFBlue CHSIFBR1C charger (see page

Power off the unit to exit and save the settings.
Warning: Do not mix battery types. Use either two Lithium 1.5V batteries, or
two Alkaline batteries, or two NiMH batteries.
Warning: Do not place the red cap switch in the NiMH position when using the
other two type batteries, either Lithium or Alkaline. Any attempt to recharge
Lithium or Alkaline batteries can lead to damaging both the unit and the
batteries.
