Modifier Key Programming
Junior, Single & Double keyas are modifier
keys set to work only with the “Cone” key.
To register press the appropriate modifier key
before the “Cone” key. A different PLU will
be registered for each modifier:
Junior-Cone will register PLU#30001
Single-Cone will register PLU#30002
Double-Cone will register PLU#30003
To accomplish this, the “Cone” key is set as
PLU #30000 with an inactive status. (The
Cone key will not work without having a
modifier key pressed first.)
Each Modifier key is set with the Program 70
status of 201, meaning that the modifier will
affect the PLU number, the modifier
descriptor will not print (the actual PLU will
provide the complete descriptor, i.e. JUNIOR
CONE) and the first digit will be affected.
The value of affected digit program (Program
90) will be set differently for each modifier
key: the JUNIOR key will have the value of
“1”, the SINGLE key will have a value of “2”
and the “DOUBLE” key will have a value of
“3”.

key programming.
