Overflow in implicit constant conversion help!

I clicked verify and it did not comeback with any errors but two warnings which were " warning: overflow in implicit constant conversion
Mouse.move(390, 195);" and " warning: overflow in implicit constant conversion
Mouse.move(445, 229);"

I'm trying to make a teensy(3.2) move the mouse to automate a function, but have these errors. Any suggestions on solving them?

The parameters are "signed char", meaning they have a range of -128 to 127. If you want a larger movement you'll have to call Mouse.move() more than once with values in that range.

See Mouse.move() - Arduino Reference.
