1 Open the jack cover of the DC IN 5V jack.
2 Connect the supplied AC adaptor to the DC IN 5 V jack and plug it into a wall outlet.
3 Open the stand, and adjust the receiver angle.
Notes
ˎ ˎ Place the receiver on a stable surface. If the receiver is placed on an unstable surface or in an inclined position, it
may fall or topple over, and may cause injury.
ˎ ˎ Adjust the receiver angle until it is stable. If you incline the receiver too much, the it may topple over.
Carrying the receiver
When you carry the receiver by hanging it on your neck or attaching it to your belt, the receiver
operates on the built-in battery. The BATT/CHG indicator light will show the remaining battery
power.
Attaching a strap to the receiver
Note
ˎ ˎ No strap is supplied. Use a strap of sufficient strength.
Attaching the receiver to your belt
Belt
Note
ˎ ˎ If you attach the receiver to your belt using the belt clip, handle it carefully to avoid dropping it.
Built-in battery (Receiver only)
When the receiver is connected to the AC adaptor and the built-in battery has discharged to a
certain level, the built-in battery starts charging automatically and is charged up to full charge.
Battery life
It will last about 16 hours after it has been fully charged (when operated with the medium
volume level, and Voice Activation off).
Charging duration
About 7 hours are required to charge the empty battery to its full capacity, in an ambient
temperature of 25 °C (77 °F). Charging may take longer, depending on whether or not the
receiver is turned on and other ambient conditions.
Checking the remaining battery power
When the battery power is getting low, a beep sounds and the BATT/CHG indicator light of the
receiver flashes in red.
Notes
ˎ ˎ If you consume the battery power completely and leave it like that, the battery life may be affected. Charge the
battery by connecting it to the AC adaptor as soon as it has been used up.
ˎ ˎ Even if you do not intend to use the receiver for a long period, charge the battery to its full capacity once every
6 months to maintain its performance.

transmitted. We recommend turning the transmitter on first.
ˎ ˎ Do not turn the power on when the receiver is close to the transmitter. Feedback noise will be generated.
Tips
ˎ ˎ According to the level of sound detected by the microphone of the transmitter, more SOUND LEVEL indicator lights
(up to 3 lights) turn on in red.
ˎ ˎ The receiver sounds an alarm when it is moved out of the transmission range.
Turning off the power
1 Set the Power/VOICE ACT switch of the receiver to OFF.
2 Set the power switch of the transmitter to OFF.
Customizing the Digital Audio Nursery Monitor
Adjusting 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 the VOLUME control. If the volume level is set too high and is
accompanied by a shrill noise, reduce the volume.
To increase sound volume, turn the VOLUME control downward. The green area of the
VOLUME indicator is extended.
To decrease sound volume, turn the VOLUME control upward. The green area of the VOLUME
indicator is reduced.

VOLUME control
The sound volumes decreased.
The sound volumes increased.
Note
ˎ ˎ The SOUND LEVEL indicator lights turn on according to the input sound level received from the transmitter. The
level setting of the VOLUME control does not affect it.
Using the Voice Activation function
The Voice Activation function ensures that when the transmitter has detected sound of more
than a certain volume, monitor sound is automatically output from the speaker of the receiver.
This function is usable when it is not required for the receiver to constantly check for sounds
from the nursery, such as when the baby is sleeping quietly or the parents are sleeping.
1 Set the Power/VOICE ACT switch to VOICE ACT to turn the function on.
