Input of Frequencies
In the frequency input dialog two ways of entering a new frequency are possible:
1)
input using the numeric buttons, and
2)
input using the arrow buttons.
The “Frequency/channel input dialog” is divided into:
ƒ Section “Active… [MHz]”, which shows the presently active frequency (s. Figure 14, field A).
ƒ Section “Standby … [MHz]”, which allows the input of a new frequency (s. Figure 14, field B).
Note
The frequency, which is simply typed in, is not immediately set to the “Standby”.
To set the new value to “Standby” value, press “OK”.
ƒ “SWAP” function (s. Figure 14, field C and position 3) allows switching between the two
displayed frequencies.
Thus, one of them is always active and the other one can be set to “active” at one button
press, whereby the previously active frequency becomes the “standby” frequency instead.
