How to switch between the low- and high-frequency displays
You can switch between the low-and high-frequency displays
from the pop-up menu. Open the pop-up menu, tap [Frequen-
cy], then turn on [HF] or [LF] as appropriate.
Note: Using the same method mentioned above, you can
switch the video on the dual frequency display and zoom dis-
play.
Dual frequency display: Swaps the low-frequency and high-frequency images (de-
fault setting: low frequency on the left and high frequency on the right).
Zoom display: Switches between single images (low frequency or high frequency).
7.3.2 Dual frequency display
The dual frequency display provides both low and high frequency pictures, the low fre-
quency on the left half (default). Use the dual frequency display to compare the same
picture with two different sounding frequencies.
How to select the dual frequency display
Tap the screen to show the pop-up menu. Tap [Mode], then turn on [Dual Freq.]. The
frequency selected with [Frequency] appears on the right half of the screen.

™

when the split range is used.
3. Tap [OK].
4. Tap the close button on the title bar to finish.
5. Pinch the high- and low-frequency displays to change their range.
