If the [%+] or [ % - ] key is used immediately after a previous balance
entry through the [PB+] key, the percent rate is added to or
subtracted from the previous balance. But a use of a % key after the
[PB-] key will result in an error.
TRF

When a charge posting operation is ended with the [Chg] key, this key
is used to transfer the entire balance with no payment.
To operate, depress the [TRF] key after the [Chg] key. All the
balance is transferred, the transferred amount is printed as the new
balance, and a receipt is issued. ([Chg] may be omitted in this case.)
Additional Department Keys
A maximum of 15 department keys including the present department keys
may be installed.
Single-item Department Keys
Some or all of the depatment keys may be programmed to be ’’Single-item
Department Keys". A Single-item Department Key is used to quicken a
single cash sale item entry process instead of depressing a department
key and [AT/TL] key. On depressing a Signle-item Department Key, the
sale is immediately finalized and a receipt is issued.

M i s e
) MISCELLANEOUS MEDIA KEY [ M i s e ]
The [MISC] key may be added as a non-cash media key. By adding this
key, any other non-cash media sales than check and charge may be
finalized with this key. The functions and programmabilities for this
key are the same as the [CHK] key.
Additional % Key
A maximum of two % keys including the present % keys may be installed
on the keyboard. That is, if one [%+] key and one [%-] key are
already installed, no other % keys can be added. However, the two %
keys can be programmed to be used as both %+ or both %- keys.
