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

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

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

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.
