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

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.

• 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.
