Battery life
(approx. hours for continuous standby)
Sony rechargeable battery pack BP-TR10
* 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
Cavity for hook
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
j
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

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. C–
)
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
(JEITA*)
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
• Keep the transmitter out of the reach of the baby.
Do not place the transmitter inside a crib or
playpen.
• 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. C–
)
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.
Polarity of the plug
• 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.
Using Belt Clip (See Fig. C–
)
The receiver has a belt clip located on the rear. It is
convenient when you move around, for example,
when you clean up the room, etc.
Insert your finger into the cavity for hook and slide
upwards as illustrated, then hang the belt clip onto
your belt.
When fixing the receiver onto your belt, be sure to
turn off the receiver, and disconnect the AC power
adaptor from the DC IN 9V jack and the wall outlet.
Then close the lid of the DC IN 9V jack securely.
Notes
• When using the belt clip, the receiver can be
operated only on battery.
• When you are not using the belt clip, push it back
to its original position.
• Make sure that you do not move outside the
effective operating range of the system.
