5 Antenna Information
5.1 Antenna Type
TCLWRQS1 uses the onboard PCB antenna.
5.2 Antenna Interference Reduction
To ensure optimal Wi-Fi performance when the Wi-Fi module uses an onboard PCB antenna,
it is recommended that the antenna be at least 15 mm away from other metal parts.
To prevent adverse impact on the antenna performance, do not use copper or route cables
along the antenna area on the PCB.
For details about the onboard PCB antenna area on a module, see Figure 3.

6.2 Production Instructions
1. Storage conditions for a delivered module are as follows:
(1) The moisture-proof bag is placed in an environment where the temperature is
below 30°C and the relative humidity is lower than 70%.
(2) The shelf life of a dry-packaged product is six months from the date when the
product is packaged and sealed.
Attention:
(1) In the whole process of production, operators at all stations must wear
electrostatic rings.If the 30% circle is pink, bake the module for 4 consecutive
hours.
(2) During operation, strictly prevent water or dirt from touching the module

Federal Communications Commission (FCC) Declaration of Conformity
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:
(1) This device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
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.

environment. This equipment should be installed and operated with minimum distance 20cm between the
radiator and your body.
Important Note
This radio module must not installed to co-locate and operating simultaneously with other radios in host
system except in accordance with FCC multi-transmitter product procedures. Additional testing and
equipment authorization may be required to operating simultaneously with other radio.
The availability of some specific channels and/or operational frequency bands 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 host product manufacturer is responsible for compliance to any other FCC rules that apply to the
host not covered by the modular transmitter grant of certification. The final host product still requires Part
15 Subpart B compliance testing with the modular transmitter installed.
The end user manual shall include all required regulatory information/warning as shown in this manual,
including: This product must be installed and operated with a minimum distance of 20 cm between the
radiator and user body.
This device have got a FCC ID：2ANDL-TCLWRQS1.The final end product must be labeled in a visible
area with the following: “Contains Transmitter Module FCC ID:2ANDL-TCLWRQS1”
This device is intended only for OEM integrators under the following conditions:
1)The antenna must be installed such that 20cm is maintained between the antenna and users, and
2) The transmitter module may not be co-located with any other transmitter or antenna.
As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM
integrator is still responsible for testing their end-product for any additional compliance requirements
required with this module installed.
