more at three seconds, indicating that the
IR transmission is over. Upon successful
data transfer (usually in less than two
seconds) the transmitter’s backlight will
light up and the transmitter will transmit
a radio signal on the same channel as the
receiver. The Signal Strength and Diversity
Indicators on the receiver’s LCD display will
then light up, indicating that the IR link is
completed. If no action is taken during the
three seconds of active data transfer, the
receiver and the transmitter units do not link
and transmitter’s previous program channel
remains unchanged.
Note:
The IR link is infrared light and thus works
best when this data transfer is accomplished
in a light-shielded or darker environment.
It may not be successful in a brightly lit area.
If the transfer fails, repeat the procedure in
a darker location or somehow shield the link
from outside light to success-fully program
the transmitter with the pre-programmed
group and channel info from the receiver.
Manual Programming (GrP/CH and Volume):
The transmitter’s frequency is set using
the
Set Button (44)
and then the
(UP) or
(DOWn) Buttons (43)
. To start, press the
Set button once. The backlight on the
lCD
(36)
will light up and the
Group Icon (37)
will
flash. Use the or buttons to change
the group. When a group selection is
finished, press the Set button again for the
channel selection. The
Channel Icon (38)
will
now flash. Again, use the or buttons
to change the channel as desired. When
the group/channel selection is done, press
the Set button to enter volume level input
setting and then press or to change in
four steps from 0dB to -30dB (for loudest
input) or press the Set button a second time
to exit to the main menu. To change volume
input level only, press the Set button three
times to select the volume input level
setting. Use the or to change in four
steps from 0dB to -30dB (for loudest input).
The level is preset at 0dB for GT and -10dB
for LT/HM. These settings are optimal for
most applications.
For normal operation, the transmitter should
have the same Group/Channel as displayed on
the receiver
. After programming is finished,
close the battery compartment door,
ensuring that it latches. The BT-1KU is
now ready for use.
BT-1KU Transmitter Switches
At Power Off the transmitter will store
the last settings entered and re-display
them at the next power on where it can be
reprogrammed to any new Group/Channel.
The default factory setting is Group 08,
Channel 00.
The
rF Power level Switch (42)
is used
to select Hi/Low power transmission
(see
Operating the BT-1KU Handheld
Transmitter
).
When the
Set Button (44)
is pressed, the
LCD main menu
will cycle in this order:
MAIN MENU
>
GROUP
>
CHANNEL
>
VOLUME
> repeat
The selected function will flash for 20
seconds before returning to the main menu.
The
(UP) or (DOWn) Buttons (43)
work
in the set mode only. They can be used to
change any Group/Channel as selected (if
not using IR Sync from receiver). They can
also be used to select the desired Input
audio level VOL setting.
