Transmitter Setup
Slide down the
Battery Compartment Cover (
1
)
, as
shown, exposing the battery compartment. Insert 2 fresh
AA alkaline batteries or the optional BCBRBP Battery
Pack NiMH rechargeable batteries while observing the
correct polarity as marked. Set the
Channel Selector
Switch (2)
to the desired channel of operation and slide
the cover back into position on the unit.
(Note: Make sure
the transmitter is OFF when changing the batteries.)
Operation
a.The BCWBT is provided with a 3.5mm
Locking Jack
(3)
for connecting a microphone. Plug in the connector
of the
Lavaliere/Lapel Mic (4)
.To secure the connec-
tion, turn the metal slip ring on the plug clockwise to
thread it on the jack.To unplug, reverse the process.
Clip the transmitter to your clothes/belt or, for best
results, hang the transmitter around your neck using
the supplied lanyard. Make sure the BCWBT
Emitter
(5)
has a clear line-of-sight with the BCIRS IR Sensors.
Position the microphone at a distance of about six inches from your mouth. Do not place the micro-
phone too close to the mouth.
(See page 8 for operation information on the BCHM Headset microphone.)
b.Adjust the BCWBT’s
Volume Control (6)
to minimum and slide the
Power Switch (7)
to the ON
position.The two-color Power
ON/LOW Battery LED Indicator
(
8)
will light green, indicating that
the transmitter is ON. In the case of low power batteries, the indicator will light red, indicating that the
alkaline batteries should be replaced with fresh ones or the NiMH batteries should be recharged.
(Note:The Rechargeable Battery Pack should only be charged with the Battery Charger listed. Never attempt to
recharge alkaline batteries.)
The optional BCBRA Recharging Adapter can be plugged directly into the
BCWBT DC Input
Charge Jack (9)
from an AC power outlet for easy charging of NiMH batteries.
When the recharging adapter is plugged in, the recharger’s LED Indicator will light red. The LED
Indicator will light green when the batteries are charged.
(Note: Always remove batteries from the BCWBT
Transmitter when not in use.)
c.The BCWR Receiver's IR LED Indicator of the corresponding channel should now be lit green.While
wearing the microphone and speaking, slowly increase the BCWBT’s
Volume Control (6)
and adjust
the volume control on the receiver, and also on the Mixer/P.A. to the desired level while taking care to
avoid acoustic feedback.The microphone is now ready to use. For optimum performance and range,
make sure that the IR
Emitter (5)
is not covered by the body or clothing and has an unobstructed
line-of-sight with the IR Sensor.
(Note: Observe care in selecting volume, transmitter location, and speaker placement so that acoustic feedback
[howling and screeching] will be avoided. Microphones that are farther from the sound source, such as lapel mics,
require more acoustic gain and thus are also more prone to feedback than close-source mics such as handheld
and headset mics that are used close to the mouth.)
