Nady Systems 4W-1KU Owner's manual - System Operation
Buttons Function
The Power Button (1) is used to turn ON or
OFF all four receivers at the same time.
When this power button is pressed for
two seconds, the blue backlights on the
lCD Displays (8) will light up indicating the
receivers are on. Press the Power button
again for two seconds to turn off the
receivers. The backlight on the LCD will
display “OFF” indicating the receivers
are off. At power-off the 4W-1KU QUAD
receivers will store the last settings entered
and re-display them at power-on. It can be
reprogrammed to any new Group/Channel,
or Volume level. The default factory setting
is Group 00 (Receiver 1) and 03 (Receiver 2),
06 (Receiver 3) and 09 (Receiver 4), Channel
00 and Volume 63 are same for all receivers.
The
(Up) or (Down) Buttons (7) are active
while in the Set mode, or can be used to
change Volume level (11) at anytime.
When the Set Button (6) is repeatedly
pressed the lCD Display (8) menus will cycle
in the following order:
MAIN MENU
>
VOLUME
>
GROUP
>

>
MAIN MENU
(repeats)
During manual programming, the selected
function will flash for five seconds or press
the Set button to confirm the selection and
the display will return to the main menu.
The aUTO-SCan / aSC (IR Sync) Button (2)
has two functions:
Long press (hold ~2 seconds) for AUTO-
•
SCAN for finding a clear channel within
the frequency band (with all TXs turned off
at this time). Clockwise running segments
on the LCD display show the scanning
is in progress which normally takes ten
seconds. When it finds an interference-
free channel, it will display and store that

channel for use. Then ASC IR Sync the
TX as described below.
Short press (~ 1 second) to transfer the
•
selected frequency information from
the receiver to the transmitter for easy
synchronization prior the transmitter can
be used. When short pressing the ASC
IR Sync button while the main menu is
displayed, the IR leD (4) will light up red
and stay for about three seconds. This
indicates IR transmission is in progress
and IR data is transferring during this
period. A transmitter should be used
at this time to receive data from the
receiver (see IR Sync Programming in
Programming sections of HT-1KU and
BT-1KU transmitter sections). Upon
successful data transferred (usually in
about three seconds) the IR LED stops
and 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 manual channel selection
is preferred, skip this selection.
Note: If you are using multiple transmitters at
the same location, set up the first transmitter
and leave it ON and keep it 3 ft. away from
the receivers. Then start AUTO-SCAN on the
second receiver. This avoids duplicate selection
of the same channel as already selected for the
first receiver. Using these procedures for the
remaining receivers to be used.
If you are not satisfied with a channel after
scanning, repeat anytime for locating another
free channel.
