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.

 Do not use the antenna to hang the receiver on the

wall. Be sure to use the cavity for hook.

* Measured by JEITA (Japan Electronics and Information

Technology Industries Association) standards. The actual

battery life may vary depending on the circumstance of the unit.

When to recharge the rechargeable battery pack

If the sound becomes distorted or interrupted, we

recommend that you recharge the battery pack. When

the battery pack is used up, the POWER/BATT indicator

starts flashing and the receiver sounds a beep. If the

battery pack is extremely used up, the beep may be

interrupted or the POWER/BATT indicator may flash

when you turn on the power. Recharge the battery pack

as soon as possible in either case. Recharge the battery

pack for more than 22 hours so that the battery pack is

fully charged. Turn off the receiver before charging the

battery pack. The CHARGE indicator remains lit even

after charging has been completed.
Charging duration

Approximately 22 hours are required to charge the

battery pack to its full capacity.
Notes on the rechargeable battery pack

 The battery pack will gradually discharge over a long

period of time, even if not in use.

 If you leave the weak battery pack inside the receiver

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.

 Do not use any other rechargeable battery pack.

Notes on AC adaptor

 When the AC adaptor is not used, be sure to turn off

the receiver, and unplug it from the DC IN 9V jack and

the wall outlet. Then close the lid of the DC IN 9V jack

securely.

 Use only the supplied AC adaptor. Do not use any

other AC adaptor.
