The best way is with an antenna analyzer but that is too expensive unless you do SWRs for a living. The meter on the radio should suffice for your needs.
Adjust the screw on the antenna until it is about 1/2 inch out.
Place the srf/swr switch to swr.
Go to channel 1 and note the SWR reading on the meter.
Go to channel 40 and do the same.
If channel 1 SWR is higher than channel 40, then screw the tuning screw out a turn or 2.
If channel 40 SWR is higher than channel 1, then screw the tuning screw in a turn or 2.
Repeat until the SWR on channel 1 is the same as 40. Channel 19 will be the lowest.
If you are not comfortable using the built in SWR meter, you will have to invest around $20 for a small SWR meter.
