First, press Save/Recall and select the Device from which the Radio Standard
will be read. Most likely this will be USB or SD Card.
Press Measure 1 OR Freq/Dist then More

Then select the *.csv file using the ▲|▼ arrows or rotary knob and press
Enter.
Custom Radio Standards can be removed from the FieldFox by selecting
Measure 1 then Radio Standard then Delete Radio Standard.
Then select the *.csv file to delete using the ▲|▼ arrows or rotary knob and
press Enter.

must first delete the *.csv file from the FieldFox, then re-upload the file that
contains the standard. A predefined internal standard (such as GSM 450) can
NOT be deleted from the FieldFox.

selecting channel numbers rather than frequency. Once enabled, the channel
number is appended to the X-axis frequency range.
