We get a lot of calls on Sharp Cash Registers where the end-user needs to turn on a function or feature on their cash register. Many times the end-user is unable to program the functions they wanted because Sharp Cash Registers have a hidden mode on the keylock called service where special features have to be activated.
So to set the record right as we do have many end-users mad about this and think it is just a ploy the dealers use to generate revenue, the service mode is in fact hidden and the key does not come with a machine purchase. Sharp has always done this and it makes some sense. With the service key it is possible to wipe out your entire program with one keystroke. Sharp does not offer keys to end-users nor do they mention the service mode in the manual.
We do offer service keys for $10.00 each (we make them) and you will need a service manual. Some of the machines we have elected to just send a service key with it as some basic functions have to be turned on with the key.
So don’t be mad at the dealer, it’s Sharp’s fault. Thanks

I was trying to program the tax rate in a new Sharp ER-A320, but was actually programming the tax tables. Now I can’t get the register to use the tax rate. Can I easily undo whatever I did concerning tax tables? Also, I was using a SRV key instead of MA, by mistake. Thanks.
Hmmn, I have never ever programmed the tax table so I’m not sure what happens. However that machine is pretty simple so you might want to do a service reset and start over. I’m assuming since you have a service key you know how to do that? I not comfortable posting the master reset because so often people do it when it is not needed and they loose everthing!
As far as using that key, it does not matter what key, it is the key lock mode you use. Also you might want to re-program the tables to zero then try the rate.
Hope that helps a little.

I forgot, Sue I do have service manual for that machine posted at http://www.cashregisterguys.com/sharpmanuals.html it does have the master reset procedure in it. AND PLEASE ANYONE READING THIS POST USE AT YOUR OWN RISK. WE ARE NOT RESPONSIBLE FOR YOU CLEARING YOUR MACHINES PROGRAM AND ALL SALES DATA BY USING THE MATERIAL WE PROVIDE!!!! THEY ARE USEFUL TOOLS BUT THEY CAN BE DANGEROUS!
