2. Set the desired power range by using the push-button switch on the
front panel labeled POWER 300W/30W . With the switch in the out

the 300W range is selected.
3. The Peak Reading feature may be switch on/off by using the push-
button switch labeled POWER PEAK/AVG . Peak reading is
activated when the switch is locked in.
4. SWR is indicated at the intersection of the two meter pointers.
While transmitting, read the SWR from the red SWR line nearest the
intersecting point.
There is a fair amount of dissipation in the coupler (8W) at 300 watts
on any band. Operation at this power level must be held to a short time
(typically 1-2 minutes). If you see the meter register changes in reverse
power, this indicates that the special diodes are changing in forward
drop and that the high power should be removed. After a reasonable
amount of time, the wattmeter can be used again.
