This key may also finalize received-on-account payments if not
prohibited in the system option.
This key may also finalize the current sale of charge posting. In
this case, the amount displayed by the [Chg] key is the sale total
including the previous balance. However, it is programmable to
display the sale total excluding the previous balance by the [Chg] key
depression in that case.
OTHER OPTIONAL KEYS
The following keys are not shown in the TYPICAL KEYBOARD LAYOUT on page 6.
However, any of them may be installed if the customer requires. But please
note that some of the present keys may have to be dispensed with or additional
memories may have to be installed to gain additional functions. Please
contact your TEC representative if any of the following keys is necessary.
Additional Department Keys
A maximum of 60 department keys including the present department keys
may be installed.
SHIFT
DEPARTMENT SHIFT KEY [SHIFT]
This key functions similarly to the "Shift Key" on a ordinary
typewriter keyboard. Two different departments will be programmed on
one Department Key, and shifting is possible from one department to
the other by depressing the [SHIFT] key. For example, Department 1
can be used as Department 31 if the [SHIFT] key is depressed prior to
[DEPT 1] key.
In this case, the number of all the department keys on the keyboard
must be 30 or less. Thus the keyboard can spare space for other
functions keys despite the number of departments.
The [SHIFT] key is effective to shift a department for only one entry;
therefore, the shifted department can only be repeated by depressing
the [RPT] key but not by depressing the same department key.
Additional [X+] or [Z-] Keys
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 present
two % keys can be programmed to be used as both %+ or both %- keys.
Mise
TEND
MISCELLANEOUS MEDIA TENDER KEY [MISC]
This is one of additional media keys that may be installed besides the
present media keys. This key may be used to finalize a sale paid in
media other than cash and check. This key has the same functions and
programmabilities as the [CHECK] key, and usually used as a "Tender"
key.
