6 ) if the phone established a connection with a Bluetooth device , when there is an incoming call. you could
turn on and hang up calls by a short press PWR button
7 _ Precautions A
1) PCB Iayout:the antenna portion of the bluetooth module Is PCB antennasinoe the metal will weaken
the function of the anuanna, in layout to the module. the below of the module antenna is non—paved and
traces.
Antenna and metal objects should not be too close. for example. the battery. chip. and metal objects
2) should not overiapModule's Antenna on the motherboard should be at the plate edge,
Regarding wireless Bluetooth operation environmentWireless signalsinoluding Eluetooth are affected
3) by the surrounding environment to a large extent. For example: trees. and other obstaciu metal will

4 ) Since Blueloolh module must be supported by an existing systems and placed In the housingtsinoe
the metal shell is shielding elected on the radio lrequency signal. It is not recommended to be
installed in a metal housing.

FCC Statement:
This equipment has been tested and found to comply with the limits for a Class 5 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 han'nful
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 to an outlet on a circuit different from that to which thereceiver is connected.
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: Modifications to this product will void the user‘s authority to operate this equipment.
RF Radiation Exposure Statement:
1.This Transmitter must not be cc - located or operating in conjunction with any other antenna or transmitter.
2.This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment
should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body.
FCC Infonnalion to OEM integrator
The OEM integrator has to be aware not to provide information to the end user regarding how to
install or remove this RF module in the user manual ol the and product.
The user manual which is provided by DEM integrators (or end users must include the following
information in a prominent location
1,To comply with FCC RF exposure compliance requirements. the antenna used tor this transmitter
must be Installed to provide a separation distance at at least 20 cm from all persons and must not
be co - located or operating in conjunction with any other antenna or transmitter. except in
accordance with FCC multi - lransmitter product procedures.
2. Only those antennas with same type and lesser gain llled under this FCC ID number can be used
with this device
3, The regulatory label on the final system must include the statement: “Contains FCC ID: ZACPA-BT or using electronic labeling
method as documented in KDB 784748.
A. The final system integrator must ensure there is no instruction provided in the user manual or
customer documentation indicating how in install or remove the transmitter module except such
device has implemented two - ways authenlication between module and the host system
5,The final system integrator must provide a host or housing which provides shielding for this module that satisfied the requirement
of KDB 996369 section B
