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.

Setting Up
Turning on the power
Set the OFF/ON switch of the transmitter and the OFF/
ON/VOICE ACT switch of the receiver to ON to turn on
the power.
The POWER indicator of the transmitter and the
POWER/BATT indicator of the receiver will light up. To
turn off the power, set the OFF/ON switch of the
transmitter and the OFF/ON/VOICE ACT switch of the
receiver to OFF.
Setting the frequency channels
Up to 27 channels can be set through the CH selectors by
changing the combination of three colors (red, yellow
and green) on the CH windows.
Set the CH selectors of both the transmitter and receiver
so that the settings of color combinations shown in the
CH windows are the same. Otherwise, the transmitter
and receiver will not function.
If the settings of the receiver and transmitter are not the
same, the RANGE ALM. indicator starts flashing and the
receiver sounds a beep.
If signal interference occurs
Set the CH selectors of both the transmitter and receiver
to another setting. Make sure that both the settings
shown in the CH windows are the same.
Setting up the transmitter
(See Fig. – )
Place the transmitter within 2 to 3 meters (6 to 10 feet)
from a crib or play area. If the child moves outside of this
range, the transmitter may not be able to detect his/her
sounds. The transmitter must be placed upright during
operation.
Tips for better reception
	Place the transmitter at a location as high as practically
possible such as on a table or on a wall.
	Make sure that the transmitter is not covered or
obstructed for picking up sounds.
	Make sure that nothing touches the antenna during
operation.
Notes
	Do not place transmitter or cord within reach of
children.
	Do not place transmitter or cord in, or attach to, crib
or playpen.
	Never use extension cords with AC adaptors. Only use
AC adaptors provided.
	Position the transmitter with the front side where the
built-in microphone is located facing the baby.
	Do not use the antenna as a carrying handle.
	Do not use the antenna to hang the transmitter on the
wall. Be sure to use the cavity for hook.
Monitoring through the receiver
(See Fig. – )
The longest distance you can place the receiver from the
transmitter varies according to obstructions and other
conditions. First, test the operating range with the
assistance of another adult, or by placing a radio, etc.,
near the transmitter. If you move outside the effective
operating range of the system, the RANGE ALM.
indicator lights up and the buzzer sounds. In such a case,
move closer toward the transmitter until the indicator
and the buzzer turn off.
Tips for better reception
	Keep the receiver upright during operation.
	Make sure that nothing touches the antenna during
operation.
The VOICE ACT function eliminates most background
noise when the receiver does not detect any sound.
Set the OFF/ON/VOICE ACT switch to VOICE ACT to
turn on this function.
When the receiver receives sounds from the transmitter,
the MONITOR indicators light up from left to right in
five steps depending on the sound level. Only one
indicator may light up if the sound from the transmitter
is not loud, or all the indicators may light up if the sound
is very loud. You can also hear sounds through the
speaker.
To adjust the volume
The volume of the sounds you receive varies depending
on the loudness of the baby’s voice, distance between the
transmitter and the baby, direction of the built-in
microphone of the transmitter, obstructions, etc.
Set the volume as required using VOL. If the volume level
is set too high and is accompanied by a shrill noise,
reduce the volume.
The volume level can be adjusted between the smallest
and biggest dots on the VOL.
Notes
	Avoid placing the units near heat sources or where they
are subject to direct sunlight, excessive dust, moisture,
or mechanical shock.
	Be careful not to drop the receiver in water, or drop
any liquid over it.
	Do not use the antenna as a carrying handle.

without charging it, the battery pack will be completely
discharged. It may require several times of charging to
recover to its full capacity.
Notes on replacing the rechargeable battery pack
	If the battery pack lasts only a few minutes even after
22 hours of charging, the battery life has expired and
needs replacement.
	Before replacing the battery pack, make sure that the
receiver is turned off.
	Replace the battery pack with a new one. Contact your
local Sony authorized dealer or service center, and ask
for a Sony BP-TR10 rechargeable battery pack.
