To Whomsoever It May Concern
This letter is being issued to confirm that Redpine Signals, Inc., will ensure that the
following information is included in the RS9113DB (FCC ID: XF6-RS9113DB, IC ID: 8407ARS9113DB) Module’s Programming Manual for customers who use this module with
different antennas to help them comply with the FCC/IC regulatory requirements for
products which use the module’s modular approval.
The list of antennas with which the module has been tested with and certified for FCC/IC
are given in Table 1 below.

Table 1: List of Antennas Used for RS9113DB FCC/IC Certification
The RS9113DB Module’s Programming Reference Manual will include the information listed
below. The Manual is provided to customers as part of the module’s collateral which also
includes the module’s software and firmware. The module’s firmware applies the
attenuations required to comply with the regulatory requirements based on the type of
antenna programmed. The commands required to program the transmit power and the
antenna type and the attenuations applied are given in the tables that follow.
1) Commands to program the antenna being used for Wi-Fi, Bluetooth and ZigBee – see
Tables 2, 3 and 4.
2) Commands to set transmit power of the module for Wi-Fi, Bluetooth and ZigBee – see
Tables 5, 6 and 7.
3) Transmit power and attenuation values used during testing with different Antennas –
see Tables 9, 10, 11 and 12.
