Quick Reference for all of the correct settings for Plantronics CS50, CS55, CS70

April 18th, 2009

Don’t want to read the entire users guide to figure out what’s wrong with your Plantronics CS50, CS55, CS70 or CS70N? I’ll make it as easy as 1-2-3 for you:

On the side of the charging base tower you’ll see a round dial with numbers on it. Line up the dial so that the number 1 is directly lined up with the raised horizontal plastic ridge to the right of the dial. This is the correct configuration setting for almost all phones in the US. Trust me. Don’t wonder about it. Just set it to 1.

Now, turn the charging base tower upside down and you’ll see a slide switch with ABCD. Set that to B. This is the outbound master volume (how loud you sound to the caller).

Next, on the back of the baser tower you’ll see another slide switch with 1234. Set that to 2. That is the incoming master volume (how loud the caller sounds to you).

You’re all set! If you hear echo when you speak, then use the down arrow button on the back side of the base tower. Press “down” arrow button several times until the echo goes away.

If you need to adjust the incoming volume, do so up on the earpiece (black rocker switch).
