Precautions
Safety Precautions
Operate the transmitter and receiver on 9 V DC. To
operate them from a house current, use only the
supplied AC adaptor; do not use any other type.
For battery operation of the receiver, use one
rechargeable battery pack BP-TR10.
Should any solid object or liquid fall into the unit,
disconnect the AC adaptor and remove the battery, and
have the unit checked by a qualified personnel before
operating it any further.
If you are not going to use the system for a long time:
– Disconnect both transmitter and receiver from the
wall outlet by pulling out AC adaptors.
– Remove the battery out of the receiver to avoid
damage from battery leakage.
If you have any questions or problems concerning your
system, please consult your nearest Sony dealer.
Precautions on Usage
This product cannot replace responsible adult
supervision of a child. It is designed to assist adults
in child supervision. Do not use it for medical
monitoring of a sick baby or child.
The transmitter detects normal sound levels within a
range of 2 to 3 meters (6 to 10 feet) from a child. If the
child moves outside of this range, it may not be able to
detect sounds from him or her.
It is essential that you check the operating range and
condition of the Sound-Sensor Nursery Monitor on
initial installation, and on a regular basis after that.
Stay close to the receiver in order to hear normal
sounds from it. Check the volume regularly to ensure
that it is set high enough.
Recharge the rechargeable battery pack in the receiver
or operate it on house current as soon as the POWER/
BATT indicator starts flashing and the receiver sounds
a beep.
The receiver can be affected by other devices in or near
your home that may interfere with the signals sent by
the transmitter. Such interference can be caused by TV
sets, cordless phones, vacuum cleaners, car ignitions,
and other electrical devices. You should test the
receiver when you expect such devices to be in
operation while you are using the Sound-Sensor
Nursery Monitor.
The signal from the transmitter can be received by
another receiver, as it uses a public air wave.
Cautions on Water-resistance (for
the receiver only)
This unit is designed so that it can be used with slight
exposure to water, rain, snow and other forms of
moisture, but there are several points on which caution
should be observed.
Do not allow it to come into contact with large
amounts of water.
Do not immerse it in water.
If water should get on it or if it should fall into water,
take it out immediately and wipe it off with a dry cloth.
To prevent the battery from corroding, wipe out the
interior of the battery compartment as follows:
– Open or close the battery compartment with dry
hands in a place without exposure to any water.
– Wipe off the battery and the inside of the battery
compartment. Give special attention to the contacts
so that no water remains on them.
