5.3 Production instructions
1. The Tuya SMT module should be mounted by the SMT device. After being un-
packed, it should be soldered within 24 hours. Otherwise, it should be put into
the drying cupboard where the RH is not greater than 10%; or it needs to be
packaged under vacuum again and the exposure time needs to be recorded
(the total exposure time cannot exceed 168 hours).
• SMT devices:
– Mounter
– SPI
– Reflow soldering machine
– Thermal profiler
– Automated optical inspection (AOI) equipment
• Baking devices:
– Cabinet oven
– Anti-electrostatic and heat-resistant trays
– Anti-electrostatic and heat-resistant gloves
2. Storage conditions for a delivered module:
• The moisture-proof bag must be placed in an environment where the tem-
perature is below 40°C and the relative humidity is lower than 90%.
• The shelf life of a dry-packaged product is 12 months from the date when
the product is packaged and sealed.
• There is a humidity indicator card (HIC) in the packaging bag.
3. The module needs to be baked in the following cases:
• The packaging bag is damaged before unpacking.
• There is no HIC in the packaging bag.
• After unpacking, circles of 10% and above on the HIC become pink.
• The total exposure time has lasted for over 168 hours since unpacking.
17 / 24
5 Packaging information and production instructions
• More than 12 months has passed since the sealing of the bag.
4. Baking settings:
• Temperature: 60°C and ≤ 5% RH for reel package and 125°C and ≤5%
RH for tray package (please use the heat-resistant tray rather than plastic
container)
• Time: 48 hours for reel package and 12 hours for tray package
• Alarm temperature: 65°C for reel package and 135°C for tray package
• Production-ready temperature after natural cooling: < 36°C
• Re-baking situation: If a module remains unused for over 168 hours after
being baked, it needs to be baked again.
• If a batch of modules is not baked within 168 hours, do not use the reflow
soldering to solder them. Because these modules are Level-3 moisture-
sensitive devices, they are very likely to get damp when exposed beyond
the allowable time. In this case, if they are soldered at high temperatures,
it may result in device failure or poor soldering.
5. In the whole production process, take electrostatic discharge (ESD) protective
measures.
6. To guarantee the passing rate, it is recommended that you use the SPI and AOI
to monitor the quality of solder paste printing and mounting.
5.4 Recommended oven temperature curve
Set oven temperatures according to the following temperature curve of reflow sol-
dering. The peak temperature is 245°C.

7 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 guar-
antee 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 in-
tended destination. The firmware setting is not accessible by the end-user.
The host product manufacturer is responsible for compliance with any other FCC rule
that applies 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-ZS4S-IPEX. The end product must be labeled
in a visible area with the following: “Contains Transmitter Module FCC ID: 2ANDL-
ZS4S-IPEX”.
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 2) The transmitter module may not be co-located with any other trans-
mitter 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 test-
ing their end-product for any additional compliance requirements required with this
module installed.
Declaration of Conformity European Notice
Hereby, Hangzhou Tuya Information Technology Co., Ltd declares that this module
product is in compliance with essential requirements and other relevant provisions
of Directive 2014/53/EU,2011/65/EU. A copy of the Declaration of conformity can be
