• Battery status indicator
In order to increase the functional efficiency of the Babyfon®, the „Power“ lamp begins to flash on the transmitter and/or receiver
if the battery/battery pack voltage can no longer guarantee safe operation. The receiver then also emits a warning tone.
2. Operating elements
(A) Transmitter
(A1) Power socket 6V DC

3. Operation
1. Putting into operation with an AC adapter:
1. Connect the power supply cable to the socket provided (A1) on the back of the transmitter, then plug the AC adapter into the
wall socket (230 V / 50 Hz). Place the transmitter at least 1 metre from the person to be monitored (see electro-smog info).
2. Check the channel selection switch (A4). The transmitter and receiver must be set to the same channel („A“ or „B“), otherwise
transmission cannot take place.
3. Now switch on the transmitter (A2). The power-on lamp (A3) lights up red, indicating that the transmitter is ready to operate.
4. You can increase the preset sensitivity (from which the transmitter is activated) using the control (A6) and adapt it to your
requirements.
5. Now set the transmission output to your requirements. If the Babyfon® is used mainly in stationary operation (transmitter in
child’s room > receiver in living room) we recommend switch position „S“ (small transmission output). For mobile use we
recommend switch position „L“ (large transmission output). Only in switch position „L“ can the range indicated be reached in
optimal conditions.
6. The transmitter (A) is now ready to operate.
(B) Receiver
1. Connect the power supply cable to the socket provided (B1) on the back of the receiver, then plug the AC adapter into the wall
socket (230 V / 50 Hz)).
2. Check the channel selection switch (B6). The transmitter and receiver must be set to the same channel („A“ or „B“), otherwise
transmission cannot take place.
3. Now switch on the receiver (B3). The power-on lamp (B4) lights up red, indicating that the receiver is ready to operate.
4. To ensure functionality, the minimum volume is preset to approx. ⁄ of the maximum volume. You can increase the volume to
your requirements.
2. Putting into operation with batteries/battery packs:
The BM 400 has an integrated battery pack charge function for the transmitter and receiver. This automatic charge function is
activated when the battery compartment contains battery packs.
N.B.: If y
ou wish to use batteries, the transmitter or receiver must not be connected via the AC adapter! This will damage
the units!
