Important
1. This module is intended to use for wireles audio and data transfer for OEM integration in
final products.
2. When integrating the THB “Bluetooth Comfort Module” into a final product, the following
information must be considered:
All products containing the module must be labelled. The label must be affixed on an
exterior surface of the end product such that it will be visible upon inspection in
compliance with the modular approval guidelines developed by the FCC.
The label must state “This device contains FCC ID QZ9-BURYBCM001”
In addition, the user manual for the end product must contain the following information:
"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."
3. Take care of electrostatic discharge while handling the module. This may destroy the
module.
4. Don´t place the module in a metal housing. This may reduce the operating distance.
5. This device and its antenna must not be co-located or operating in conjunction with any
other antenna or transmitter.
6. For using antennas not mounted on the module see related document “Bluetooth Comfort
Module Antenna Specification “. Take only the specified antennas, otherwise loss of FCC
and Bluetooth Approval will result.
7. The users manual or instruction manual for an intentional or unintentional radiator shall
caution the user that changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment.
8. The OEM Manufacturer must not describe to the end user how to install or deinstall the
Bluetooth Comfort Module.

6. Battery & charger:
Charging voltage:
External, 5V charging voltage is delivered to J4 on bottom side of PCB.
Maximum current depends on used battery & onboard charger configuration.
Battery:
Any Lithium-polymer battery may be connected to J3 on bottom side of PCB.
External resistor 10K or NTC overheating protecting thermistor must be connected
to ground on J3 to enable charger functionality.
For battery charging current setting information – please contact THB or read Microchip
