How does a person adjust the swr with the built in swr calibrator

You can't adjust the SWR with the built in calibrator. The radio has a built in SWR tester but does not have an antenna tuner.
Ideally you should tune or repair the antenna.
Secondly where that is not practical, there are antenna tuners available for sale. Find and buy one and it should correct your C/L imbalances or impedance problems.

How could I find a manual?

They are fairly straight forward to use. The dial is for selecting what you are metering. AC or DC voltage and range. Resistance. Amps. The probes may need to be plugged in differently depending on the meter function.

It should, most any Strength/Signal Wave Ratio tester works with most any radio. But then again, Marine radios are always trustworthy, a study shows that they are the best form of emergency communication. Why would you need to test it?

Instructions for a swr meter/cb radio

An SWR meter is used to see how well your antenna is matched to your transmitter output, just like using the correct speakers with an amplifier.

There are usually two readings. FORWARD and REFLECT
or FWD and REFL

Firstly, make sure the antenna selector is in the correct position and set for the antenna you are using.

Next, switch your meter to FWD (FORWARD). Switch your transmitter to low power and press the microphone key.

Next, adjust the CAL knob for the maximum power reading, but not so far that the meter exceeds maximum!

Keep the microphone key pressed and switch to REFL (REFLECT). If your antenna is matched, the meter should now give a low reading. If the reading is very high, you must match your antenna by making adjustments or by using a matching unit.

A poor match will mean a poor signal. A very poor match can damage your transmitter and cause interference.

When you have a good FORWARD reading and a low REFLECT reading, your system will be reasonably matched and you can then use higher power. Remember that you will need to reduce the CAL knob to a lower setting when running high power.
