*) To meet the requirement for radiated power from the vehicle antenna when using maximum power in Band n78, a reduction of 2.5dB of max tune-up power is needed. This power back-off is accomplished by using the SAR power limit feature. The SAR power limit is checked against the general power limit table prior to transmitting in any band when an external antenna connection is detected (normal state of operation.) Therefore, for Band n78, the SAR power limit table will contain a value 2.5dB lower than the general power limit table in use on the module. There is no effect to tune-up process or management of appropriate band output power to maintain proper connection within the allowed power range (given this 2.5dB reduction of the maximum allowed power).

The total loss in the vehicle to be declared is 5.81 dB.
