Help set up phono stage resistance with dip switch

I have a MM & MC phono stage...
Now in the manufacture book I have the following explanation of the Dip switches...

Dip #1- not for MC

Dip #2- MC 2.5k ohm load

Dip #3- MC 1.3k ohm load

Dip #4- MC 510 ohm load

Dip #5- MC 250 ohm load

Dip #6- MC On or Off

It states for MC cartridge you can set switches 2 thru 5 for several combination's of impeadance match. (you may switch 2 or 3 switches on together at once)

But that is all it really tells me, so I have guessed they want you to turn #6 on to get it into MC, Fine... Now I need to figure out which combos make, 300 ohm which is recommended for my cart, maybe a 400 ohm or something close to get a little more detail possibly which is also recommended for like rock music, or even a 200 ohm to tone the cartridge down a little if necessary. I have not heard the cartridge yet and have no idea the results I will get so I am just needing to have some kinda Ammo going in to tune this thing, Yes I could just set to the 250 ohm or whatever and come close but would really like some more options to taylor the sound a bit if necessary. I understand the higher impeadance will make a bit more aggressive, and lower impeadance will make more laid back.

Thanks to the members taking the time to read this and maybe help out.

If you turn on switches #2,#3, and #4 together,
that will give you a load resistance of 319 ohms.
If you want to calculate different load resistances,
the formula for resistors in parallel is: 1/Rt = 1/R1+
1/R2......1/Rn , where 1/Rt is the net total resistance
of the resistors in parallel. I hope this helps you out.
