Newbie to the soda machine world here!

I recently aquired a Vendo V111-214, with a CoinCo s75-9800C changer.  I plugged the machine in, and it has no problems cooliing, the issue is with the changer, or vending mechanism I think.  Inside the machine, there is a note saying that it is set up for $.50, and to use quarters only.  When I insert quarters, I can hear them go through the changer and fall into the collection box, but nothing happens when I push a vend button.  I am wondering what the first step is for me to try and get this thing working.  Thanks a lot.

First, check to see if it is set to 50 cents.  Here's the manual.
Next, make sure that you have enough product to go above the sold out mechanism (switch).

Just to add a little more to this topic....from what i've found the 9800C had six switches as opposed to the 9800B that only had 5 switches...
The six switches from what i've found are set up the same as the fix switches except with 1.60 switch at the end...i believe

So for the 9800C its
Switch 1: .5 cents
Switch 2: 10 cents
Switch 3: 20 cents
Switch 4: 40 cents
Switch 5: 80 cents
Switch 6:$1.60

Thank you guys so much!!!!  I got this machine for free from a company that said it was broken.  I checked the dip switches, and they were all turned off.  After switching the right ones on, I shut the machine, put in a couple of quarters, and voila!  My very own working vending machine.  Thanks.  The only other question I have is this.  How can I get the light for correct change only to go off?

Do you have nickels loaded in the change tubes?

Congrats on getting it working, Creighton's correct, you have to fill up the change tubes with at least about 10-nickels each to turn of the "correct change only " lamp
