Warnings:
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.
Any Changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate the equipment.
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.
FCC Modular Radiation Exposure Statement：
The antenna(s) 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, except in accordance with FCC multi-transmitter product
procedures. OEM and installers must be provided with antenna installation instructions and
transmitter operating conditions for satisfying RF exposure compliance.

Single limited modular statement:
1.This LMA does not have RF shielding and is tested and approved as standalone
configuration, additional evaluation may be required for any system integrated
this radio module.
2.The modular transmitter doesn’t have its own power supply regulation,
it’s provided by host.
9.This module need to be soldered mounting in Printer main PCB according to module circuit
diagram。
10. If the label of the module is not visible on the final device, the final device should contain the
following text: "Contains FCC ID: Z5GSCBM4A”
