For the customers in the U.S.A.
Note:
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
connected.
– 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
transmitter.
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.

to ensure that it is set high enough.
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.
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)
