5. Antenna Information
5.1 Antenna Type
Antenna can be connected only using On-board PCB antenna.
5.2 Reduce Antenna Interference
While using the On-board PCB antenna, in order to have the best Wi-Fi performance, it’s
recommended to keep a minimum 15mm distance between the antenna part and the other metal
pieces.
User’s own PCBA design is recommended NOT to pass any wire, NOT do copper pour under
the region of the module’s antenna, to avoid interferences.

²
The storage for the delivered module should meet the following condition:
1. The anti-moisture bag should be kept in the environment with temperature < 30℃ and
humidity < 85% RH.
2. The expiration date is 6 months since the dry packaging products was sealed.
²
Cautions:

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.
This equipment complies with FCC radiation exposure limits set forth for an
uncont
rolled environment. This equipment should be installed and operated with
minimum
distance 20cm between the radiator and your body.

are country dependent and are firmware programmed at the factory to match
the intended destination.
The firmware setting is not accessible by the end user.
The final end product must be labelled in a visible area with the following:
“Contains Transmitter Module 2AFNL-TYWE3S”
TYWE3S DATASHEET
This radio module must not installed to co-locate and operating simultaneously
with
other radios in host system, additional testing and equipment authorization may
be
required to operating simultaneously with other radio.
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.
This transmitter module is authorized only for use in device where the antenna
may be installed such that 20 cm may be maintained between the antenna and
users. The final end product must be labeled in a visible area with the following:
“Contains FCC ID: 2AFNL-TYWE3S”.
The OEM integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the user's manual of the end
product which integrates this module. The end user manual shall include all required
regulatory information /warming as shown in this manual
