6. POWER LED
When the on/off switch is
in the “ON” position the
power LED should glow
red. If it does not glow red
this typically means a low
battery.
7. EMITTER
The emitter must be plugged into the IRB-10 trans-
mitter and either attached to the clothing via the
clip or worn around the neck with the lanyard.
8. EXT. MIC
The provided microphone cable and mic must be
plugged into the IRB-10 transmitter. Multiple dif-
ferent microphone options are available from
Lifeline Amplification Systems including collar and
headset mics.
9. CHARGING JACK
The charging jack is used to charge the battery.
The WH-1 charging cable, rechargeable batteries,

1. FREQUENCY SELECTION
The IRB-10 can be set to transmit on either one of
two preset frequencies. This is so that two different
teachers can teach in the same room (team teach-
ing). It is also so that you can use a lapel mic and
handheld mic in the same room. While it does not
matter which frequency is chosen, two wireless
systems (microphones) can NOT be on the same
frequency at the same time. To select the desired
frequency (channel) slide the switch (1) as shown
on the back of the battery door. All systems come
pre-set to channel 1 for ease of use.
2. POWER MODE SELECTION
The IRB-10 has two power modes- “LO” and “HI”.
These modes can be selected via a power switch (2)
inside the battery compartment. The system comes
factory pre-set to the “HI” position. The only reason
to turn the power mode switch to the low position is
if the range you need is less than 15 feet or you are
experiencing low battery problems.
3. MICROPHONE GAIN
The microphone gain (volume) can be adjustable if
you experience a lower volume level than desired.
The microphone gain control is found on the inside
of the battery compartment (3). A tool has been
provided(inside the battery compartment) to adjust
the gain if necessary. Adjustment of gain control
should only be necessary if you have already tried
to adjust the volume on the amplifier and you are
still experiencing low volume.
4. BATTERY COMPARTMENT
Two AA Nickel Metal Hydride rechargeable
batteries have been included with your Freedom 2
Infrared System. These batteries should last
several hours per day for a period of at least one
year. The number one cause of battery problems is
overcharging a battery. Be sure to never charge
your battery over 72 hours. Always use Lifeline
Amplification Systems rechargeable batteries
for best results.
5. ON/OFF SWITCH
Turns the transmitter “ON” and “OFF”. If you are
not going to use the unit for more than 15 minutes,
turn the unit “OFF” to conserve battery life.
