FCC Statement
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.
The modular can be installed or integrated in mobile or fix devices only. This modular cannot be
installed in any portable device.
FCC Radiation Exposure Statement
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter. This modular must be installed and operated with a minimum distance
of 20 cm between the radiator and user body.
If the FCC identification number is not visible when the module is installed inside another device,
then the outside of the device into which the module is installed must also display a label
referring to the enclosed module. This exterior label can use wording such as the following:
“Contains Transmitter Module FCC ID: 2APJ4-SLM757 Or Contains FCC ID: 2APJ4-SLM757”
When the module is installed inside another device, the user manual of the host must contain
below warning statements;
1. 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.
(2) This device must accept any interference received, including interference that may cause
undesired operation.
2. Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
The devices must be installed and used in strict accordance with the manufacturer's instructions
as described in the user documentation that comes with the product.
Any company of the host device which install this modular with Single modular approval should
perform the test of radiated emissionand spurious emission according to FCC part 15C : 15.247
requirement,Only if the test result comply with FCC part 15C : 15.247 requirement，then the host
can be sold legally.
IC statement
This device complies with Industry Canada’s licence-exempt RSSs. Operation is subject to the
following two conditions:
(1) This device may not cause interference; and
(2) This device must accept any interference, including interference that may cause undesired
operation of the device.
Cet appareil est conforme aux CNR exemptes de licence d'Industrie Canada . Son fonctionnement
est soumis aux deux conditions suivantes :
( 1 ) Ce dispositif ne peut causer d'interférences ; etc
( 2 ) Ce dispositif doit accepter toute interférence , y compris les interférences qui peuvent
causer un mauvais fonctionnement de l'appareil.
A separation distance of at least 20 cm is maintained between the transmitter's radiating
structure(s) and the body of the user or nearby persons.
Une distance de séparation d'au moins 20 cm est maintenue entre l'émetteur rayonnant
structure (s) et le corps de l'utilisateur ou des personnes à proximité.
For a host manufacture's using a certified modular, if (1) the module's IC number is not visible
when installed in the host, or (2) if the host is marketed so that end users do not have
straightforward commonly used methods for access to remove the module so that the IC number
of the module is visible; then an additional permanent label referring to the enclosed module:
"Contains Transmitter Module IC: " 23860-SLM757" or "Contains IC: 23860-SLM757" must be
used.
