Class II Permissive Change: Add the battery base on POS Terminal, Model: S1E4 PRO.

Class II Permissive Change: Enables portable use when integrated into the POS Terminal, Model: S1E4 PRO. Device must operate with a minimum 10 mm separation distance between the device and the body for SAR compliance, as described in this filing. The highest reported SAR for body, simultaneous transmission and product specific (10g SAR) exposure conditions are 0.51 W/kg, 1.46 W/kg and 0.68 W/kg, respectively.

Single Modular Approval. Output power is conducted. This device supports 20MHz, 40MHz and 80MHz bandwidth mode. The module antenna(s) must be installed to meet the RF exposure compliance separation distance of 20 cm and any additional testing and authorization process as required. Co-location of this module with other transmitters that operate simultaneously are required to be evaluated using the FCC multi-transmitter procedures. Approved for OEM integration only. This module can only be used with a host antenna circuit trace layout design in strict compliance with the OEM instructions provided. The grantee must provide OEM integrators with installation and operating instructions for satisfying FCC multi-transmitter product guidelines. This grant is valid only when the device is sold to OEM integrators and the OEM integrators are instructed to ensure that the end user has no manual instructions to remove or install the device.


CC: This device is certified pursuant to two different Part 15 rules sections.

Class II Permissive Change: Enables portable use when integrated into the POS Terminal, Model: S1E4 PRO. Device must operate with a minimum 10 mm separation distance between the device and the body for SAR compliance, as described in this filing. The highest reported SAR for body, simultaneous transmission and product specific (10g SAR) exposure conditions are 1.20 W/kg, 1.46 W/kg and 2.59 W/kg, respectively.

Single Modular Approval. Output power is conducted. The module antenna(s) must be installed to meet the RF exposure compliance separation distance of 20 cm and any additional testing and authorization process as required. Co-location of this module with other transmitters that operate simultaneously are required to be evaluated using the FCC multi-transmitter procedures. Approved for OEM integration only. This module can only be used with a host antenna circuit trace layout design in strict compliance with the OEM instructions provided. The grantee must provide OEM integrators with installation and operating instructions for satisfying FCC multi-transmitter product guidelines. This grant is valid only when the device is sold to OEM integrators and the OEM integrators are instructed to ensure that the end user has no manual instructions to remove or install the device. This device supports LTE of 1.4, 3, 5, 10, 15 and 20 MHz bandwidth modes for FDD LTE Bands 2, 4, 25 and 66; LTE of 1.4, 3, 5 and 10 MHz bandwidth modes for FDD LTE Bands 5 and 12; LTE of 5, 10, 15 and 20 MHz bandwidth modes for FDD LTE Band 7; LTE of 5 and 10 MHz bandwidth modes for FDD LTE Bands 13, 14 and 17; LTE of 1.4, 3, 5, 10 and 15 MHz bandwidth modes for FDD LTE Band 26; and LTE of 5, 10, 15 and 20 MHz bandwidth modes for TDD LTE Bands 38 and 41.
