For the customers in the U.S.A.
This equipment has been tested and found to comply with the limits for a Class B digital 
device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a 
residential installation. This equipment generates, uses, and can radiate radio frequency 
energy and, if not installed and used in accordance with the instructions, may cause harmful 
interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this 
equipment does cause harmful interference to radio or television reception, which can be 
determined by turning the equipment off and on, the user is encouraged to try to correct the 
interference by one or more of the following measures:
–  Reorient or relocate the receiving antenna.
–  Increase the separation between the equipment and receiver.
–  Connect the equipment into an outlet on a circuit different from that to which the receiver is 
–  Consult the dealer or an experienced radio/TV technician for help.
This Transmitter must not be co-located or operated in conjunction with any other antenna or 
The following FCC statement applies only to the version of this model manufactured for sale in 
the USA. Other versions may not comply with FCC technical regulations.
The available scientific evidence does not show that any health problems are associated with 
using low power wireless devices. There is no proof, however, that these low power wireless 
devices are absolutely safe. Low power Wireless devices emit low levels of radio frequency 
energy (RF) in the microwave range while being used. Whereas high levels of RF can produce 
health effects (by heating tissue), exposure of low-level RF that does not produce heating 
effects causes no known adverse health effects. Many studies of low-level RF exposures have 
not found any biological effects. Some studies have suggested that some biological effects 
might occur, but such findings have not been confirmed by additional research. NTM-DA1 has 
been tested and found to comply with FCC radiation exposure limits set forth for an 
uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines in 
Supplement C to OET65.
Safety Precautions
ˎ Operate the transmitter and receiver on 5 V DC. To operate them from house current, use 
only the supplied AC adaptors; do not use any other type.
ˎ Place the transmitter more than 0.9 m (3 ft) away from your child.
ˎ Should any solid object or liquid fall into the unit, disconnect the AC adaptor after turning the 
unit is power off and have the unit checked by qualified personnel before operating it any 
Notes on the AC adaptor
ˎ Connect the AC adaptor to a nearby easily accessible wall outlet. If trouble occurs while the 
adaptor is in use, immediately set the Power/VOICE ACT switch of the receiver to OFF and 
disconnect the AC adaptor from the wall outlet. And also set the Power switch of the 
transmitter to OFF and disconnect the AC adaptor from the wall outlet.
ˎ The unit is not disconnected from the AC power source (mains) as long as it is connected to 
the wall outlet, even if the unit itself has been turned off.
ˎ If you are not going to use the Digital Audio Nursery Monitor for a long time, disconnect both 
the transmitter and receiver from the wall outlet by pulling out the AC adaptors.
If you have any questions or problems concerning your Digital Audio Nursery Monitor, please 
consult your nearest Sony dealer.
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 
ˎ The transmitter detects normal sound levels within a range of 2 to 3 m (6 to 10 feet) from 
your child. If the child moves outside of this range, it may not be able to detect sounds from 
him or her.
ˎ The transmission range between the transmitter and receiver is up to 270 m (900 feet) (Line 
of Sight). It is essential that you check the transmission range and condition of the Digital 
Audio Nursery Monitor on initial installation, and on a regular basis after that.
ˎ 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.
ˎ The sensitivity of the Digital Audio Nursery Monitor can be affected by other devices using 
2.4 GHz frequency, such as a wireless LAN device, a cordless telephone, or a microwave oven, 
that may be used near the transmitter and receiver. Using such devices may shorten the 
transmission range and cause sounds to be distorted.
ˎ Avoid placing the transmitter and receiver near heat sources or where they are subject to 
direct sunlight, excessive dust, moisture, or mechanical shock.
Cautions on Water-resistance (for the receiver only)
The receiver 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.
ˎ Do not allow the receiver to come into contact with large amounts of water.
ˎ Do not immerse the receiver in water. If the receiver is dropped into water, set the Power/
VOICE ACT switch to OFF immediately and disconnect the power cord. Do not use it any more 
and consult your nearest Sony dealer.

ˎ Do not pour cold or hot water directly from a faucet or hose onto the product, as it is not of 
ˎ If you use the product near water, close the jack cover of the DC IN 5V jack firmly. If it is left 
open, moisture may get inside the product and may cause a malfunction.
ˎ If moisture has getten inside the product, some may remain in its openings. Shake the 
product lightly to shed water then wipe the surface. If not, the remaining water will spill out 
when you move the product.
