must be used.

tory default values.
– Set power supply voltage 8.4 V to service battery (or 3.6 V to jig).
– Connect pulse power meter or spectrum analyzer to antenna connec-
tor.
– Check that channel is 60.
– Adjust the power level (levels 5, 15 and 19) by clicking the + and –
buttons, and change levels with ↑
