* When M405 is used, the measurement errors will occur due to how to hold of instrument and influence of
human body, because M405 is ? λ whip antenna. The error value will be several dB or more. In order to
reduce the error, separate 2650A series from human body as much as possible.

Mode Selection and Measurement
By pushing
F1
(ANT), the antenna (M401/M402/M403/M404/M405/M406/USER) can be selected
The measurement starts as soon as the antenna is selected.
