LW2602: FREQUENTLY ASKED QUESTIONS
The image on the LCD monitor is blurry or distorted.
The LCD monitor may be set at QVGA resolution. Press the VGA/QVGA button
on the front panel to switch the resolution to VGA.
The LCD monitor shows 4 split-screen images. Can
I view one, full-screen image?
Yes. The split screen image (Quad mode) allows you
to view all four channels at once. To view full-screen
single channels, press the CH button on the front
panel. Use the CH button to switch between channels
1~4, Quad mode, and Auto Scan mode.
The image from the camera(s) is choppy and/or
keeps cutting out.
The wireless receiver may be out of range of the camera(s). Use the signal bars
on the on-screen display to observe signal strength. 0~1 bars = no/weak
reception; 4 bars = strong reception.
ATTENTION: If the signal is low (e.g. 1 or 2 bars) adjust the antennas, or reposition the cameras or
receiver for best performance.

How do I add more cameras to the wireless receiver?
Additional accessory cameras must be “paired” to the wireless receiver. A
maximum of four cameras can be paired to the LW2201.
1. With the new camera powered on, press and hold the PAIR button on the
front panel of the wireless receiver for 5 seconds to activate pairing.
“Connecting” appears on-screen.
2. Press and hold the Yellow Pair button extending from the camera within
30 seconds of pressing the PAIR button on the wireless receiver. If pairing
is successful, live video from the camera will immediately appear on the
monitor.
NOTE: The camera(s) included with your system is already paired to the wireless
receiver. For more information on Adding Cameras, please refer to the LW2201
Instruction Manual.
The Receiver keeps switching channels.
The wireless receiver is in Auto Scan mode. Press the CH button once to switch
between channels 1~4, Quad Mode, and Auto Scan.
Can I lengthen or shorten the amount of time that the channels are on-
screen while in Auto Scan mode?
Yes. The on-screen time for channels in Auto Scan is called “Dwell Time.”
To set dwell time:
1. Make sure the Wireless Receiver and
cameras are fully connected and powered
on.
2. Press and hold the VGA/QVGA button
and Pair button at the same until the
Dwell Time screen appears. Continue
holding both buttons.
3. With the Pair button and VGA/QVGA
button held down, the receiver will
automatically cycle the dwell time from
1~20 seconds. The higher the dwell time,
the longer each channel remains on-
screen during Auto-Scan.
4. Release both buttons to set the desired
dwell time.
Note: If you repeat this process, the Dwell
Time screen will display the last set dwell
time.

reception.
The picture is or has
become choppy.
•The picture may become choppy when experiencing a lower
frame rate (i.e. 10 frames per second vs. a higher 20 frames
per second).
•Try moving the camera closer to the receiver.
•Remove obstructions between the Receiver and Camera.
There are problems with
the audio.

microphone

The picture appears to be
grainy when using AV out
function to view on a large
screen TV/Monitor
•The purpose of the AV output is for convenience only. When
using with large screen TV/Monitor, the picture might be grainy
as the camera limits video resolution to VGA (640x480 pixels).
This is not a product defect.
•For best performance use with TV/Monitor PIP (Picture in
Picture) function. Check your TV/Monitor product manual to
see if this feature is available on your TV/Monitor
•View video on a smaller screen TV/Monitor
