You can select between 3, 5, 7, 9, 11, and 13
graph bars.
6. Touch
to start measuring.

Displays the frequency marker “▲” and the
measurement frequency.
NOTE:
Before transmitting, monitor the
operating frequency to make sure you will not
cause interference to other stations on the same
frequency.
7. Hold down [PTT] to transmit.
• The bar graph displays the SWR.

after the measurement
The best match is
within this range.

TIP:
• Rotate
to move the frequency marker
“▲” to the current transmit frequency.
• “<<” (low) or “>>” (high) is displayed when the
transmitted frequency is out of the displayed
range.
• Touch [RECALL] for 1 second to move the
frequency marker “▲” back to the center
frequency.
• Touch the bar graph to delete the measured SWR.
