Casio TK7000 Cash Register. I have all sales appearing as CAID and none in CHID or CKID or CRID. I have checked that Program 3 Address code 08 is set correctly. What else could be affecting this?

If the sale is finalized correctly, cash, check, etc., then cash in drawer, credit in drawer, etc. should show up.

If you don't have the cash, check, credit buttons, you can program them in like this:

PGM, then 4, followed by the desired Function Key Code, and then press the Key to assign this function to, followed by pressing the Subtotal button to save.

FUNCTION - CODE - CHARACTER
Cash Amount Tendered - 001 - CASH
Charge - 002 - CHARGE
Check Tender - 003 - CHECK

Refer to the following PDF document for assigning function keys, and a list of the function codes:
