Congratulations
Giving birth to baby is the happiest experience for parents. They would offer their children
the best living quality as they can and take care of them whole-heartedly. Therefore, a baby
monitor is a necessary baby care product that helps parents pay attention to every wonderful
moment of their baby.
We have developed a 2.4G & 4 channels handheld slim size baby monitor that eliminates the
interference from crowded 900MHz band. A color LCD screen allows the parents to watch
their child. In addition, parents are able to see their baby in bright black & white view of
baby even in a darkened room.
If you want to see a bigger image of the baby on TV, a TV cable is included to help you.
First time parents may find it difficult to manage the feeding time of their baby, a digital
alarm clock is incorporated to remind the parents, “It’s time to feed the baby!”
Please read all instructions thoroughly before using your Baby Monitor.

AC Adaptor:
The AC Adaptors are low voltage power sources that allow you to use your household
electricity to run the Baby Monitor. Connect the Ac Adaptors to the AC Adaptor Jack in the
Parents and Baby Units. Both plug into any standard volt electrical outlet in your home. It
is recommended to turn off the units before plug in or unplug the adaptors.
CAUTION: These adaptors were made with a specific design for this product. They cannot
be used with any other appliance. Never use a different type of adaptor with this monitor.

laundry tub, kitchen sink or in a wet basement etc.
6. Always unplug the AC adaptors from wall outlets and remove the batteries or the
exhausted batteries from the Parents Unit during long periods of non-use.
7. Position the Baby & Parents Units and AC adaptors to allow adequate ventilation and
prevent these components from overheating.
8. To prevent overheating, keep the Baby & Parents Units and AC adaptors away from heat
sources such as radiators, heat registers, stoves, other appliances (including amplifiers)
or direct sunlight that produce heat.
9. Use only the AC adaptors provided. Use of any other adaptors may damage the Baby
& Parents Units. Plug the AC adaptors into standard household current only! To
prevent entanglement and overheating, DO NOT use extension cord.
10. Position the AC adaptor cords so that they are not walked on or pinched by items placed

Care and Maintenance
1. The Baby Monitor is for indoor use only. Do not place the Baby Unit under direct

from rooms near the Baby Unit may be broadcasted as well. To protect your privacy,
always turn the Baby Unit off when not in use.
2. It is possible for the Parents Unit to pick up sounds or display interference from other
signal producing devices including other audio or video monitors which broadcast in the
2.4GHz range. To minimize this potential problem, 4 independent channels are
available for your use.
3. If the Parents Unit experiences interference, simply switch both the Baby & Parents
Units to another channel. Selecting a channel is usually a one-time adjustment. If
interference persists on all channels, please refer to the Troubleshooting Section.
Testing
It is very important to test the transmission of Baby Unit and reception of Parents Unit before
use or whenever you change the location of either Parents / Baby Units.
1. Place Baby Unit in room where you intend to use it. Position it in the most appropriate
location for monitoring the baby (on top of a table, dresser, or on the wall). Turn on the
Baby Unit by switching the ON / OFF switch to ON.
2. Direct the camera lens towards the area you want to see on the Parents Unit screen.
While testing, it may be helpful to place an object, such as a doll or stuffed animal, in the
area you want to monitor.
3. Place the Parents Unit in different locations you intend to use inside the house. As with
any audio equipment, feedback or a high pitched sound may occur if the Parents & Baby
Units are too close to each other.
4. Set both units into the same channel.
To test video reception quality
5. Check the video reception on the Parents Unit screen. Make sure you check the
reception in all areas you intend to use both units.
6. To adjust Brightness, Contrast, or Color, please refer to the Operation Section.
7. The Baby Unit will automatically switch to night vision mode when it is placed in a
completely darkened room. In night vision mode, the picture will be black and white.
To test sound reception quality
8. Stay in the room with the Baby Unit, speak in both a whisper and a normal conversation
level from where the child is being monitored. During sound testing, keep in mind the
sound level of your child and test accordingly.
9. Keep the Baby Unit far enough away from the Parents Unit to prevent feedback noise.
Place the Baby Unit in a different room than the Parents Unit is sufficient.
Baby Unit Location & Set-up
You can position and adjust camera in different ways to provide the best view of your baby.
The Baby Unit can be easily mounted on wall, or simply placed on a stable, flat surface, such
as a dresser, table top or shelving unit.
IMPORTANT: Once you have selected a location for mounting, test the reception of the Baby
Monitor BEFORE installing any wall mount screws. If interference or other problems occur,
please refer to the Troubleshooting Section.
WARNING:
In selecting a location to mount the Baby Unit, keep the following in mind:
- To prevent entanglement, only mount the Baby Unit at where its AC adaptor cord is
OUT OF CHILD’S REACH.
- To prevent entanglement and overheating, only mount the Baby Unit at where the
AC adaptor cord can reach a standard wall outlet. Unwrap and fully extend the
AC adaptor cord. NEVER use an extension cord.
- For best viewing, position the Baby Unit approximately 3’ (1m) away from the
child.
- Mount the Baby Unit in a location where the camera lens is unobstructed. Use the
tilt and swivel adjustments to properly aim the camera.
- Allow adequate ventilation of the Baby Unit when mounted on a wall. DO NOT
mount it directly above heating vents, other heat generating sources or in direct
sunlight.
