INSTALLATION

BABY UNIT:

The baby unit is powered from the supplied xed power adapter. The power

adapter can be connected to a 230V electrical outlet.

Place the baby unit in the nursery. It is recommended to keep the baby and the
baby monitor at a minimum distance of 2 meters. Ensure that the baby cannot
touch the baby monitor or the power adapter cord.

The baby unit can also be mounted on the wall. There is an opening for mounting
located at the back of the baby unit.

PARENT UNIT:

The parent unit is powered by an included NiMH battery pack (4.8V). The parent

unit is not xed to a power adaptor so it can be used cordless.

ENTITLED ‘BABY MULTIPLE
UNITS’.

Explanation of the CTCSS code:
Continuous Tone Controlled
Squelch System is the tone code
that is sent when transmitting. This
code is not an audible tone.
Only when the tone code from the
baby unit corresponds to the tone
code from the parent unit, will the
parent unit display the signal. This
prevents the baby monitor from
interference from other devices
that may communicate on the
same channel.

MULTIPLE BABY UNITS

After you have purchased loose baby units (DBX-83) you can set up multiple
babies ‘monitoring’. Ensure that the baby units and the parent unit are connected
on the same channel and sub-channel. In case this does not work, you can also
choose an alternate monitoring, see below:

ALTERNATE MONITORING OF 2 BABY UNITS:

Baby units:

1. Set the two baby units on different channels (the sub-channel setting may be
selected too)

Parent unit:

1. First set the parent unit to the same channel and sub-channel as the 1st baby
unit, press the

USER TIPS

GENERAL:

* The baby monitor is only to be used as an additional aid and NOT as a
substitute for an adult or responsible baby-sitter.
* Check the proper functioning of the baby monitor each time before use and
regularly during use.
* You do not need a license in order to use this baby monitor cordless. This
system can be used in a domestic situation. There is no guarantee that there
will always be an interference-free signal.
* Always switch off the units when not in use.

PLACEMENT:

* DO NOT place the baby unit in the bed with the baby and keep a minimum
distance of 2 meters between the baby and the baby unit. Also make sure that
the baby cannot touch the power adapter cord.
* Do not place the baby unit or the parent unit in direct sunlight or in a damp
place.

POWER SUPPLY:

Batteries:
The parent unit has a rechargeable battery pack that must be installed with the

following battery specications:

* Format: 4x AAA
* Type: NiMH (Nickel-Metal-Hydride), rechargeable
* Power: 600mAh or more

Battery indicator:
The parent unit has a built-in battery indicator ( ) shown on the display
screen. If the battery icon shows full, the battery pack is charged. If the battery
icon shows empty or half full, the battery pack needs to be recharged. Once
plugged in the battery indicator will show that it is charging until the battery pack
is fully charged. The batteries will be fully charged after 14 hours after which
the power adaptor can be unplugged from the unit and from the electrical wall
outlet. The adapter can remain permanently connected as the charging current is
controlled electronically.

Adapters:
Only use the included power adapters. Connecting a power adapter other than
the included adapter can damage the electronics of the baby monitor.

12

RADIO LINK:

* The DBX -82 baby monitor is a transmitter/receiver that uses radio waves on
a 446 MHz band. The signal may be disturbed by external factors such as
other baby monitors, radios, transmitters or cordless phones, etc. If your are
experiencing radio interference, changing the channel will most often be the
best solution.
* The range of the baby monitor is up to 3Km. The range can depend on local
conditions such as high buildings, and high-voltage overhead lines. An opti­ mum range is achieved if the baby unit has a clear range to the parent unit.

* If you are taking the baby monitor abroad, please rst look into the local

restrictions on the use of PMR446 equipment where you will be staying.
* The product is permitted in Belgium, Denmark, Germany, Finland, France,
Great Britain, Ireland, Italy, Luxembourg, Netherlands, Austria, Portugal, Spain,
Iceland, Sweden and Switzerland. If the country of your choice is not on this
list, please consult the relevant country embassy. Amended legislation may
make it possible for this product to now be allowed.
* Note that the signal from your baby monitor may be heard by other 446 MHz
baby monitors, radios or receivers.
* The baby monitor should never be used outside during a thunderstorm.

MULTIPLE BABY UNITS:

* When two or more baby units are transmitting at the same time, it may be
possible that they push away each other’s signal, rather use the alternate
monitoring method.

SERVICE & MAINTENANCE:

* Only clean the baby monitor with a damp cloth. Before cleaning, the power
adapter should be taken out of the electrical wall outlet.
* Ensure that water and / or sand cannot come into the units.
* It is not permitted in any manner whatsoever to make changes to the
electronics or to the antenna of the baby monitor. Servicing the device should

only be done by qualied technicians.

ENVIRONMENT:

* If the baby monitor needs to be discarded, hand it over to your
supplier. They will dispose of the baby monitor in an environmentally
friendly manner.
* Dispose of the battery pack in an environmentally-friendly manner
according to your local regulations. Never throw away batteries with
your household waste.
