1.3 FCC Compliance Statements

FCC Section 15.21 Information to user.

Any changes or modifications to the equipment operation settings must be approved by the

NextNav, LLC for FCC compliance; otherwise the user's authority to operate the equipment

will be voided.

Section 15.105(b) Class A digital device Information to the user

This equipment has been tested and found to comply with the limits for a Class A digital

device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable

protection against harmful interference when the equipment is operated in a commercial

environment. This equipment generates, uses, and can radiate radio frequency energy and, if

not installed and used in accordance with the instruction manual, may cause harmful

interference to radio communications. Operation of this equipment in a residential area is

likely to cause harmful interference in which case the user will be required to correct the

interference at his own expense.

3.2 Tune-up procedure not to exceed maximum TX power

ACSVfile(configurationfile)pertransmitterarecreatedbytheNOCengineerbasedonthe

installationparameterssuchaslinelengths,antennatypeetc.

The TX output power level setting is contained in the CSV file.

The output power is adjusted by the ‘attenuation’ setting. This value in the CSV file is

calculated by a formula to set the output power (not to exceed 4W EIRP). The variables used

in the calculation include PA Gain (Gpa), TX Antenna Gain (Gant), TX filter insertion loss

(ILflt), internal cable loss (ILint), external cable loss (ILext), and transceiver output power

(PTCVR).
