Keyboard bug When I press the characters ´ and ~ they show up duplicated. Like this ´´ and ~~. This only happens whith this two buttons. Even when the shift is on. ´´``~~^^, see?

Turn your key to PGM enter 2 subtotal enter 0132 and press subtotal now you enter your 21 or 24 characters for the first line and press CA or the lower right hand button. Now enter 0232 and press subtotal and again enter characters and press CA or the lower right hand button.
Follow this for 4 lines and when all done press Subtotal.
I believe the register you have will show you the characters on the keyboard and just use those to make your logo.

try checking your keyboard if some characters are pressed. The reason here is that, maybe you pressed it too hard last time you used it. Making one of the characters you pressed stuck. It is advised to check it.

sir if u wants to type the special characters then press the shift key before pressing that button.

You need a new keyboard.

Have you tried the Num Lock button?

A Security Code Bug in some Kenwoods
There is a reported bug in the security code handling of some Kenwood stereos. In models with thie bug, the security code is stored incorrectly. The workaround is to enter the wrong security code.

In models with this bug, you have to decrement the third character of the security code by one. If your security code was 1111, you would enter your security code as 1101. If your security code was 9999, you would enter 9989.

i hope this works for you.
