3.5 Multiband Mode
Multiband mode displays the SWR for four different frequencies at a time. This feature can be

use the standard procedure for changing the frequency.
The Run/Hold [ ] button controls the run status. The measurements can be stopped at any time
by pressing the Run/Hold [ ] button and resuming them by pressing this button again.
