Using your Babyfon

1. Make sure that both devices are switched on and that the same channel is selected.

2. Set the response sensitivity of the microphone on the baby device to the level you

require. To begin with, we recommend a middle position that can later be adjusted
as required.

3. Set the volume on the parent device to the level required. If the baby device is

activated by a noise in the baby's bedroom, transmission starts automatically and the
power-on lamp of the parent device changes from green to red for the duration of the
transmission.

Explanation of functions

Reception control indicator / reception monitoring

There is regular radio contact between the baby device and the parent device. The recep-
tion control indicator on the parent unit indicates whether there is still sufficient contact
to the baby device. All 4 lamps glow during full reception; only one lamp glows when
reception is weak. If radio contact breaks down completely, for example because the baby
device is outside the range, or because the batteries in the baby device are empty, the
parent device emits an alarm tone after a short time. In addition, the power-on lamp flas-
hes. The alarm tone and flashing stop automatically as soon as radio contact is resumed.

Digital pilot tone / preventing interference

Besides the sounds made by the baby, the baby device also transmits an inaudible signal
tone. The parent device only begins reception when this signal tone is received. This prac-
tically rules out the reception of external wireless baby monitors. In rare cases, however,
interference from other wireless devices in the vicinity may occur. In the event of such
interference or poor reception, switch both devices to the other channel.

250 m range

In ideal conditions, the range of your Babyfon outdoors is approx. 250 metres. Obstacles
such as walls, ceilings or large objects affect the range. The more obstacles there are
between the baby and parent devices, the smaller the range becomes.

Using the battery pack supplied

Parent device

1. Remove the belt clip from the device by sliding the clip downwards.

2. Open the battery compartment by loosening the screw on the battery compartment lid.

3. Insert the battery pack supplied in the battery compartment, observing the correct

polarity. Make sure that the charging contact has been made in the battery
compartment (see B22 on parent device).

4. Slide the battery compartment lid back on to the battery compartment and tighten

the screw again. This ensures that the battery compartment cannot be opened by
accident.

5. To re-attach the belt clip to the device, insert and slide upwards.

6. Connect the AC adapter to the connector on the parent device. The battery pack is

now charged automatically. Charging is complete after approx. 15 hours.

Baby device

The battery pack supplied can also be used for the baby device. Proceed as you did with
the parent device. If you want to power both devices with battery packs, you can order an
additional battery pack (Babyfon® model number EAB 4) from a specialist dealer.

Using other battery packs or batteries

The parent and baby devices can also be powered with standard AAA battery packs or
non-rechargeable 1.5V AAA batteries. However, standard AAA battery packs cannot be
charged using the devices.

Battery alarm

A signal tone and the flashing power-on lamp warn you as soon as the battery pack or
batteries in the parent device are empty. You should then insert new batteries or recharge
the battery pack.

Disposal of batteries

Consider the environment when disposing of the batteries or battery packs, which must
not be thrown away with domestic rubbish. Do not use old and new batteries or different
battery types simultaneously. Remove batteries from the device if it is not to be used for a
long time.
