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.
