Antenna

Antenna type

TYLC7V uses an external spring spiral antenna with a gain of 2.0 dBi.

Antenna interference reduction

To ensure optimal WiFi performance when the WiFi module uses an external spring spiral antenna, it is recommended that the antenna be at least 15 mm away from other metal parts.

Antenna specifications

The specifications of the antenna are as follows:

Production instructions

1. Tuya’s stamp hole package module must be mounted by SMT machine, and the mounting must be completed within 24 hours after unpacking and programming of the firmware. Otherwise, it must be packaged again under vacuum. The module must be baked before mounting.

   • SMT equipment
     • Reflow soldering machine
     • Automated optical inspection (AOI) equipment
     • Nozzle with a 6 mm to 8 mm diameter
   • Baking equipment
     • Cabinet oven
     • Anti-static heat-resistant trays
     • Anti-static heat-resistant gloves

2. Storage conditions for a delivered module are as follows:

   • The moisture-proof bag must be placed in an environment where the temperature is below 30°C and the relative humidity is lower than 70%.
   • The shelf life of a dry-packaged product is 6 months from the date when the product is packaged and sealed.
   • The package contains a humidity indicator card (HIC).
     

3. Bake a module based on HIC status as follows when you unpack the module package:

   • If the 30%, 40%, and 50% circles are blue, bake the module for 2 consecutive hours.
   • If the 30% circle is pink, bake the module for 4 consecutive hours.
   • If the 30% and 40% circles are pink, bake the module for 6 consecutive hours.
   • If the 30%, 40%, and 50% circles are pink, bake the module for 12 consecutive hours.

4. Baking settings:

   • Baking temperature: 125±5°C
   • Alarm temperature: 130°C
   • SMT ready temperature after natural cooling: < 36°C
   • The number of drying times: 1
   • Rebaking condition: The module is not soldered within 12 hours after baking

5. Do not use SMT to process modules that have been unpacked for more than 3 months, because electroless nickel/immersion gold (ENIG) is used for PCBs and they are seriously oxidized after more than 3 months. SMT is very likely to cause pseudo and missing soldering. Tuya is not liable for such problems and consequences. Tuya is not liable for such problems and consequences.

6. Before SMT, take electrostatic discharge (ESD) protective measures.

7. To reduce the reflow defect rate, draw 10% of the products for visual inspection and AOI before the first mounting to determine proper methods for controlling the oven temperature and attaching and placing components. Draw 5 to 10 modules from subsequent batches each hour for visual inspection and AOI.

Recommended oven temperature curve

Perform SMT based on the following reflow oven temperature curve. The highest temperature is 245°C. The reflow temperature curve is shown as below:

Appendix: Statement

FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this device.

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 device has been tested and found to comply with the limits for a Class B digital device, according to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This device generates, uses, and can radiate radio frequency energy and, if not installed and used following 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 device does cause harmful interference to radio or television reception, which can be determined by turning the device 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 device and receiver.
• Connect the device 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.

Radiation Exposure Statement

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

Important Note

This radio module must not be installed to co-locate and operating simultaneously with other radios in the host system except following FCC multi-transmitter product procedures. Additional testing and device authorization may be required to operate simultaneously with other radios.

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 with 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/warnings 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 has got an FCC ID: 2ANDL-TYLC7V. The end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID: 2ANDL-TYLC7V”.

This device is intended only for OEM integrators under the following conditions:

The antenna must be installed such that 20cm is maintained between the antenna and users, and the transmitter module may not be co-located with any other transmitter or antenna.

As long as the 2 conditions above are met, further transmitter tests 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.
