2.2. L10 features
2.2.1 General specification
The L10 GPS module brings the high performance of the MTK positioning engine to
the industrial standard. The module supports 210 PRN channels. With 66 search
channels and 22 simultaneous tracking channels, it acquires and tracks satellites in
the shortest time even at indoor signal level. This versatile, stand-alone receiver
combines an extensive array of features with flexible connectivity options. The
embedded FLASH memory provides capacity for storing user-specific configuration
settings and allows for future updates. L10 advanced jamming suppression
mechanism and innovative RF architecture provides a high level of immunity for
jamming, ensuring maximum GPS performance.

4. Compliance with FCC Regulations
FCC Section 15.21 Information to the user
Changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate the equipment.
Section 15.19 Labelling requirements
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.
When the L10 is integrated into a final product, the FCC ID label must be visible through a window
onthefinaldeviceoritmust bevisiblewhenan accesspanel，doororcoveriseasily removed.If not,
a second label must be placed on the outside of the final device that contains the following text：
“Contains FCC ID：XMR-16182009003 ” L10 FCC label is shown as：
Section 15.105 (b)
Note: This equipment has been tested and found to comply with the limits for a Class B digital
