• Interference from another electrical appliance.
Turn off the appliance, or move it further from
the receiver.
Sound-Sensor
The slots and openings in the cabinet are provided for necessary ventilation. To ensure reliable
operation of the appliance, and to protect it from overheating, these slots and openings must never be
blocked or covered.
Precautions
Safety Precautions
• Operate the transmitter only on 120 V AC, 60 Hz;
and the receiver on 9 V DC. To operate the
receiver on house current, use only the supplied
AC power adaptor; do not use any other type.
For battery operation, use one rechargeable
battery pack BP-TR10.
• Should any solid object or liquid fall into the unit,
disconnect the AC power 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 the plugs of both
AC power cord and AC power adaptor
respectively.

USE
Power Source
This appliance should be operated only from the type of power source indicated on the marking label.
If you are not sure of the type of electrical power supplied to your home, consult your dealer or local
power company. For those appliances designed to operate from battery power, or other sources, refer
to the operating instructions.
You are cautioned that any changes or
modifications not expressly approved in this
manual could void your authority to operate
this equipment.
Shrill noise

• Volume is too high.
– Remove the battery out of the receiver to avoid
damage from battery leakage.
Grounding or Polarization
This appliance is equipped with a polarized AC power cord plug (a plug having one blade wider than
the other), or with a three-wire grounding type plug (a plug having a third pin for grounding). Follow
the instructions below:
If you have any questions or problems concerning
your system, please consult your nearest Sony
dealer.
Alarm continues to sound although the distance
between the transmitter and the receiver
becomes within operating range.

INFORMATION
This equipment has been tested and found to
comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference in a residential
installation. This equipment generates, uses and
can radiate radio frequency energy and, if not
installed and used in accordance with the
instructions, may cause harmful interference to
radio communications. However, there is no
guarantee that interference will not occur in a
particular installation. If this equipment does cause
harmful interference to radio or television
reception, which can be determined by turning the
equipment off and on, the user is encouraged to try
to correct the interference by one or more of the
following measures:
-For the appliance with a polarized AC power cord plug:
This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to
insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact
your electrician to have a suitable outlet installed. Do not defeat the safety purpose of the polarized
plug by forcing it in.
-For the appliance with a three-wire grounding type AC plug:
This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to
insert the plug into the outlet, contact your electrician to have a suitable outlet installed. Do not defeat
the safety purpose of the grounding plug.
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.

Overloading
Do not overload wall outlets, extension cords or convenience receptacles beyond their capacity, since
this can result in fire or electric shock.
• 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.
When not in use
Unplug the power cord of the appliance from the outlet when left unused for a long period of time.
To disconnect the cord, pull it out by grasping the plug. Never pull the plug out by the cord.
