BT-8U BODYPACK MIC TRANSMITTER
1. Snap open the
BATTERY DOOR (13)
and insert a fresh 9V alkaline or NiMH
battery into the
BATTERY COMPARTMENT (14)
observing the correct polarity.
Close the battery door to its original position and completely cover the battery.
Fresh alkaline batteries can last up to 10 hours in use, but in order to ensure
optimum performance, it is recommended that the battery be replaced after 6-8
hours of use. A NiMH battery should be replaced with another recharged fully
(with separate charger, not supplied, and as per its charging instructions) when-
ever low or dead battery status is indicated as per the following.
2. Selecting Audio Input Operating Mode
The BT-8U is equipped with two
INPUT SELECTOR SWITCHES (15)
located
under the cover on the circuit board for selecting the type of audio input you
will be supplying to the transmitter. Select from the choice of three positions:
INSTRUMENT (for guitar, bass, etc.), HEADWORN MIC, and LAVALIER MIC
(Condenser Microphones).
(Note: Use only the input audio source as per the input selected with the
internal
AUDIO INPUT SELECTOR SWITCHES (15)
or the audio will not be
optimal–a muddy or distorted sound may result.)
There are two switches with selectable positions GT, HM, LT together at the
same time.
To select inputs: (see chart on page 9)
A. Instrument — set both switches to “GT”
B. Headworn Mic — set both switches to “HM”
C. Lavalier Mic — set both switches to “LT”
3. Connecting for Selected Input
The BT-8U is provided with a 3.5 mm
LOCKING JACK (16)
for connecting
the audio input selected. Connect either the
INSTRUMENT CORD (17)
or the
HEADWORN MIC (18)
or
LAVALIER MIC CORD (19)
as desired, according to
the input selected. To secure the connection, turn the slip ring on the plug clock
wise to thread it on the jack. To unplug, reverse the process. Slip the transmitter
into a pocket or
CLIP (20)
it on to your clothes or instrument strap (if using the
BT-8U as an instrument transmitter).
4. Turn on the BT-8U by sliding the
OFF/STANDBY/ON SWITCH (21)
to the
STANDBY position (transmitter on, audio muted) or the ON position (transmit-
ter and audio both on). The
BATTERY INDICATOR LED (22)
will give a single
quick flash, indicating usable battery strength. In the case of a dead or low bat-
tery, the LED either will not go on at all or will stay on continuously, indicating
that the battery should be replaced with a fresh one. To conserve battery life,
turn unit off when not in use.
5. The BT-8U transmitter is now ready to use. The
SIGNAL LED (5)
on the
DKW-8U receiver should now be lit, indicating a received signal from the trans-
mitter. Adjust the volume of the receiver as per the Connecting the Audio Output
of the above DKW-8U receiver instructions.

1. Release the
BATTERY COVER (9)
by pressing the locking tab and slide
down as per the arrow, exposing the
BATTERY HOLDER (10)
. Insert two
fresh AA alkaline or NiMH batteries, observing the correct polarity as marked,
and slide the battery cover back on to the microphone. Make sure the cover is
closed completely. Fresh alkaline batteries can last up to 10 hours in use, but
in order to ensure optimum performance, it is recommended that you replace
the battery after every 6-8 hours of use. NiMH batteries should be replaced with
fresh ones recharged fully (with separate charger, not supplied, and as per its
charging instructions) whenever low or dead battery status is indicated as per
the following.
2. Turn on the HT-8U by sliding the
OFF/STANDBY/ON SWITCH (11)
to
the STANDBY position first (transmitter on, audio muted) or the ON position
(transmitter and audio both on). The
BATTERY INDICATOR LED (12)
will give
a single quick flash, indicating usable battery strength. In the case of a dead or
low battery, the LED will either not go on at all or will stay on continuously, indi-
cating that the batteries should be replaced with fresh ones. To preserve battery
life, turn the transmitter off when not in use.
3. The microphone is now ready to use. The
SIGNAL LED (5)
on the DKW-8U
receiver should now be lit, indicating a received signal from the transmitter.
When ready to speak, slide the
OFF/STANDBY/ON SWITCH (11)
to the ON
position. Adjust the volume of the receiver as per the Connecting the Audio
Output of the above DKW-8U receiver instructions.
[Note: Observe care in selecting P.A. volume, transmitter location and speaker
placement so that acoustic feedback (howling or screeching) will be avoided.]
