3.2 Mounting condition
To achieve better RF performance, the area around antenna in red color as below
is the minimum safe area which should be kept away from copper and any other metal.
And it is recommended to lay the antenna at the edge of the mother board while
mounting the Module.

3.3 Reset
This Module is reset from several sources: RST# pin, power-on reset, USB
charger attach reset, UART break character and software configured watchdog timer.
The RST# pin is an active low reset and is internally filtered using the internal
low frequency clock oscillator. Keep RST# for low period >5ms is recommended.

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 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 Caution:
Any changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
