Introduction
Thank you for selecting the Guardian Angel. This
highly configurable wireless audio/video monitoring
system enables you to set up a monitoring network
quickly and easily without the need to install wires and
cables.

colour TFT LCD screen and built-in speaker
• 2.4 GHz signal avoids interference from 900
MHz cordless phones
• Adjustable antenna transmits up to 300 feet
(FCC - USA)
• Four-channel capability allows a single receiver
to receive signals from up to four different trans-
mitters

Setting Up the GA-253
Setting Up the Camera/Transmitter
This chapter takes you through the steps required to set
up the Guardian Angel. Depending on the model you
purchased, your Guardian Angel will come equipped
with either a fixed mounting bracket or a tripod. For
instructions on setting up the tripod, see the next sec-
tion, Attaching the Camera to the Tripod on page 6. For
instructions on setting up the fixed mounting bracket,
see Setting Up the Fixed Mounting Bracket on page 8.

Setting Up the Tripod
Attaching the Camera to the Tripod
1. Hold the camera firmly to avoid dropping it.
2. Screw the threaded top of the assembled angle
bracket clockwise into the hole on the underside
of the camera body.
Positioning the Tripod
The camera tripod is equipped with adjustable legs to
allow positioning of the camera at a range of heights.
Each of the three legs is individually adjustable to allow
compensation for uneven surfaces. The camera mount
angle bracket at the top of the tripod can be adjusted to a
suitable angle by loosening the angle bracket screw, set-
ting the angle, then tightening the screw.

Take the following points into consideration when plan-
ning a location for your camera:
• The camera should be positioned so that the view
of the area to be monitored is unobstructed.
• The line of sight between the camera and the
video monitor should be as clear as possible.
Reducing the number of doors, walls and win-
dows between the camera and the video monitor
improves reception quality.
• You must ensure the area in wish you wish to set
up the camera has a power outlet.
When positioning the camera:
1. Make sure the camera is securely attached to the
tripod.
2. Position the tripod in the desired location, adjust-
ing the legs and angle as necessary.
3. Test the reception of the video monitor/receiver
in locations where you plan to use the receiver.
See the section Adjusting Reception Quality on
page 19 for information on improving wireless
transmission quality.

Attaching the Mounting Bracket to a Fixed Sur-
face
You may choose to attach the camera mount to a fixed
surface such as a wall or ceiling; however, the following
points should be taken into consideration when planning
a location.
• The camera should be positioned so that the view
of the area to be monitored is unobstructed.
• The line of sight between the camera and the
video monitor should be as clear as possible.
Reducing the number of doors, walls and win-
dows between the camera and the video monitor
improves reception quality.
• You must ensure the area in wish you wish to set
up the camera has a power outlet.
To mount the camera to a fixed surface:
1. Make sure the mounting assembly components
are screwed together firmly.
2. Hold the base of the mount against the fixed sur-
face and point the camera at the area to be moni-
tored.
3. Have another person test reception of the video
monitor/receiver in locations where you plan to
use the receiver. See the section Adjusting
Reception Quality on page 19 for information on
improving wireless transmission quality. Deter-
mine the optimum camera placement before pro-
ceeding to the next step.
4. Using a sharpened pencil, mark the location of
the three mounting bracket holes on the fixed
surface (e.g. wall).
5. Drill three holes at the locations you marked.
6. Push the wall plugs into the holes.

English
7. Use a Phillips screwdriver to screw the base
mount to the fixed surface.
8. Attach the camera to the angle bracket and make
final adjustments to the camera angle. Tighten
the angle bracket thumb screw.
Setting Up the Video Monitor/Receiver
The video monitor is designed for portability and con-
venience. It can be held in your hand and carried
around, stored in a pocket, or placed at a comfortable
viewing angle on a flat surface.

Using Batteries
Using batteries provides convenient, cable-free power
for the receiver. Normal operating times are as follows:
Operating time can be extended when the receiver is in
LCD saving mode. The receiver can also be plugged
into an electrical outlet using the power adapter as
explained in the following section.
When the batteries no longer contain enough charge to
power the receiver, it will automatically shut down.
There is no audible or video warning prior to shutdown.
Caution:
• Incorrectly replacing the batteries may result in
explosion.
• Replace batteries with the same or equivalent
type of battery.
Never force the pins of a power adapter into an electric
outlet. Purchase a plug adapter if necessary.

be used interchangeably between the camera/
transmitter and the video monitor/receiver. Read the
warning below before proceeding.
Warning:
• Do not use power adapters in outdoor locations.
• Do not place power adapters in areas where they
may come in contact with liquids.
• Never force the pins of a power adapter into an
electric outlet. Purchase a plug adapter if neces-
sary.
Plugging In the Power Adapters

Using the GA-253
This section explains how to set up and use the GA-253
as a wireless security system or as a wireless A/V enter-
tainment hub.
Using the GA-253 as a Wireless
Audio/Video Security System
Setting Channels
The GA-253 can transmit and receive audio and video
signals on four distinct frequencies or channels. This
enables you to monitor up to four different cameras
using a single receiver, monitor a single camera with
two receivers, or use any other combination of transmit-
ters and receivers.
Setting Channels for Single Camera Use
1. Make sure the camera/transmitter and video
monitor/receiver are powered on. See Turning
the Power On on page 12.
2. Push the channel selector button on the camera
to select a channel. The green channel indicator
LED switches to the next channel (1, 2, 3 or 4)
with each button press. Select channel 1.
