Requirement Compliance:

Yes or No along with a justification Yes. Physical shield box covers all RF parts except the F-antenna. Peripheral interface parts are not shielded Yes. The transceiver has buffered data input / output ports. 2 The radio elements must have the radio frequency circuitry shielded. Physical components and tuning capacitor(s) may be located external to the shield, but must be on the module assembly The module must have buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal Grundfos Holding A/S SCALA1 Module Integration Guide Version 1.0.1 The module must contain power supply regulation on the module The module must contain a permanently attached antenna, or contain a unique antenna connector, and be marketed and operated only with specific antenna(s), per Sections 15.203, 15.204(b), 15.204(c), 15.212(a), 2.929(b) The module must demonstrate compliance in a stand-alone configuration The module must be labelled with its permanently affixed FCC ID label, or use an electronic display

(See KDB Publication 784748 about labelling requirements) The module must comply with all specific rules applicable to the transmitter including all the conditions provided in the integration instructions by the grantee The module must comply with RF exposure requirements Yes. Module contains a voltage regulation Yes. External to the shield, the Printed Circuit Board has a F-type antenna, solderconnected to the matching network Yes. Module is to be part of a host product. It is listed in standalone configuration, with only power and data (USB) supply leads Yes. Label is affixed to RF shield box Yes. Yes. Bluetooth module is Bluetooth Low Energy (BTLE) and will not have enough power to exceed SAR limits. It is also to be mounted >20 cm from any bodyparts. 3 Grundfos Holding A/S SCALA1 Module Integration Guide Version 1.0.1 Module Integration Host product exploded view Module placement in Host product The module must be placed in a location where there are no metal or conductive parts between the radio module and the user. 4 Grundfos Holding A/S SCALA1 Module Integration Guide Version 1.0.1 Antenna placement in Host product The module has a PCB trace F antenna with 0 dBi gain in the max. direction. The antenna is located outside the RF shield of the module and must be kept free of conductive parts and wires. The PCB antenna is located under the silkscreen text BLE ANT on the PCB component side and is visible on the non-component side of the module PCB GND considerations in Host product The module antenna uses the GND plane of the module and is not dependant of the host GND plane construction. RF exposure considerations of Host product Because the radiated power (EIRP) is 0 dBm and only the integrated antenna can be used, the host product cannot radiate dangerous amounts of RF energy that can be absorbed by the user. The host is mobile and must be more than 20 cm from the users head and body at all times Other considerations This module may not be co-located with other transmitters or transmit simultaneously with radios within 20 cm. 5 Grundfos Holding A/S SCALA1 Module Integration Guide Version 1.0.1 Host manual considerations The host manual must contain instructions that the user may not be closer than 20 cm from the RF parts of the module. 6 Grundfos Holding A/S SCALA1 Module Integration Guide Version 1.0.1 Regulation information The SCALA1 module is marked with MODEL: SCALA1, manufacturer name and labelled with FCC ID and ISED IC. Module identification The Radio module is a monolithic PCB with the module label affixed Module label The module label contains the following information FCC ID: OG3-SCALA1 IC: 10447A-SCALA1 MODEL: SCALA1 GRUNDFOS HOLDING A/S FCC It is the responsibility of the host product manufacturer to ensure continued compliance against FCC Part 15B.
