ESP32-SL specification V1.0

XX

channel. 
Additional testing, Part 15 Subpart B disclaimer   
The  module without  unintentional-radiator  digital  circuit,  so  the  module  does  not required  an 
evaluation by FCC Part 15 Subpart B. The host should be evaluated by the FCC Subpart B.   
ATTENTION   
This device is intended only for OEM integrators under the following conditions: 1)  The  antenna 
must be installed such that 20 cm is maintained between the antenna and users, and 
2) This device and its antenna(s) must not be co

located with any other transmitters except in

accordance with FCC multi

transmitter product procedures. Referring to the multi

transmitter

policy, multiple transmitter(s) and module(s) can be operated simultaneously without C2P.
3) For all products market in US, OEM has to limit the Operating Frequency: 2400 ~2500MHz
by supplied firmware programming tool. OEM shall not supply any tool or info to the end

user

regarding to Regulatory Domain change.

USERS MANUAL OF THE END PRODUCT:   
In the user manual of the end product, the end user has to be informed to keep at least 20cm 
separation with the antenna while this end product is installed and operated. The end user has to 
be informed that the FCC radio

frequency exposure guidelines for an uncontrolled environment 

can be satisfied. The end user has to also be informed that any changes or modifications not 
expressly approved by the manufacturer could void the user's authority to operate this 
equipment.   
If the size of the end product is smaller than 8x10cm, then additional FCC part 15.19 statement is 
required to be available in the users manual: This device complies with Part 15 of 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.

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