Introduction
DSST-24M is a spread spectrum radio modem
with TTL. It is designed for data acquisition and
control application between host and remote
sensors. It is also useful for those applications, the
cable wire is inconvenient to be installed. The
DSST-24M can be used in not only peer to peer
mode but also multi-point structure.
Based on direct sequence spread spectrum and
RF technology operating In ISM bands. The
Frequency Range is
2410.496MHz~2471.936MHz. The Channel
Spacing is 4.096MHz.

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 needed.
Consult the dealer or an experienced radio/TV technician for help.
Warning: Changes or modifications to this unit not expressly approved by the party responsible for
compliance could void the user authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
The users manual or instruction manual for an intentional or unintentional radiator shall caution the user
that changes or modifications not expressly approved by the party responsible for compliance could void
the user’s authority to operate the equipment.
CAUTION:
1. To comply with FCC RF exposure compliance requirements, a separation distance of
at least 20 cm must be maintained between the antenna of this device and all
persons.
2. This Transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter
This device is intended only for OEM integrators under the following conditions:
1)
The antenna must be installed such that 20 cm is maintained between the antenna
and users.
For laptop installations, the antenna must be installed to ensure that the
proper spacing is maintained in the event the users places the device in their lap
during use (i.e. positioning of antennas must be placed in the upper portion of the
LCD panel only to ensure 20 cm will be maintained if the user places the device in
their lap for use) and
2)
The transmitter module may not be co-located with any other transmitter or antenna.
As long as the 2 conditions above are met, further transmitter testing will not be
required.
However, the OEM integrator is still responsible for testing their
end-product for any additional compliance requirements required with this module
installed (for example, digital device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE:
In the event that these conditions can not be met
(for example
certain laptop configurations or co-location with another transmitter), then the FCC
authorization is no longer considered valid and the FCC ID can not be used on the final
product.
In these circumstances, the OEM integrator will be responsible for
re-evaluating the end product (including the transmitter) and obtaining a separate FCC
authorization.
End Product Labeling
This transmitter module is authorized only for use in devices where the antenna may be
installed such that 20 cm may be maintained between the antenna and users (for example
access points, routers, wireless ASDL modems, certain laptop configurations, and similar
equipment).
The final end product must be labeled in a visible area with the following:
"Contains TX FCC ID: Q6M3SDSST-24M".
RF Exposure Manual Information That Must be Included
The users manual for end users must include the following information in a prominent
location "IMPORTANT NOTE:
To comply with FCC RF exposure compliance
requirements, the antenna used for this transmitter must be installed to provide a
separation distance of at least 20 cm from all persons and must not be co-located or
operating in conjunction with any other antenna or transmitter."
Additional Information That Must be Provided to OEM Integrators
The end user should NOT be provided any instructions on how to remove or install the
device.
