4. While holding the mic button adjust the
SWR CAL knob so the meter swings to
the CAL mark on the right side of the
meter.
NOTE: Calibration must be made in an
open area (never in a garage). The vehicle’s
doors must be closed. No one should be
standing near the antenna. (See your antenna
directions for more complete information.)
5. While still holding down the mic button,
set the S/RF SWR CAL
SWR position, to read the SWR reading.
6.
Repeat the same steps two through five
on Channel 1 and 40. This will check
SWR for all channels.
NOTE:
When switched to SWR position the
meter needle should ideally be as far to the left
as possible. Anything over 3 is not acceptable.
The antenna indicator will light. A slight
antenna height adjustment (higher or lower)
may be required. Repeat recalibration steps.
