Note1: When charging complete and the adapter is still in, the battery voltage will slowly drop down.
when the voltage drop is larger than 100mV from the full voltage, the re-charging cycle will start.
Note2: If the battery voltage during plug in is larger than 4V, the charging current will be limited to 0.25C
to avoid the battery voltage overshoot.
FCC:
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.
Changes or modifications not expressly approved by the party responsible for compliance could void the
user’s authority to operate the equipment.
This device is intended only for OEM integrators under the following conditions:
According to FCC Part 15 Subpart C Section 15.212, the radio elements of the modular transmitter must have
their own shielding. However, due to there is no shielding for this Bluetooth Module, this module is granted as a
Limited Modular Approval.
As long as above 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 (for example, digital device emissions, PC peripheral
requirements, etc.).
IMPORTANT NOTE: In the event that these conditions cannot be met (for example: certain laptop
configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid
and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be
responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC
authorization. Please notice that if the FCC identification number is not visible when the module is
installed inside another device, then the outside of the device into which the module is installed must
also display a label referring to the enclosed module. This exterior label can use wording such as the
following: “Contains FCC ID:OZJWLIS-04ST ” any similar wording that expresses the same meaning
may be used.
