Modifying START or STOP frequency will alter CENTER frequency and SPAN, but will preserve the STOP or START
frequency, respectively. Modifying CENTER frequency will alter both START and STOP frequencies but will preserve SPAN, if
possible (it may not be possible due to limits of supported frequency range).
The currently selected parameter (START/ STOP/ CENTER) is displayed in white. To select a different parameter,
tap on it once. The color of the keypad buttons shows which numbers can be entered at the current digit position to obtain
a valid parameter value – the numbers on the
green
buttons can be entered, the numbers on the
red
buttons cannot be
entered. If the currently entered value is valid, it is displayed in
green
(also OK button is
green
). If the value is not valid, it is
displayed in
red
(also OK button is
red
). To confirm a valid value, tap the OK button or tap the parameter’s box.
The frequency value can be entered with a precision of 0.01 MHz (10 kHz) by using the “.” on the keypad. To input a
value with decimal digits, first enter the full MHz’s, then tap the “.” button and enter the rest of the digits. Until the value is
confirmed, the digits after the point are displayed larger. If there are no digits displayed after the point, it means that they
are zeroes.
To exit the FREQ menu and return to the main screen, tap BACK.
