ENTRY IN THE " Q" (NEGATIVE) MODE (Mode Lock: [ 2 ] )
When several items are returned at a time, turn the Mode Lock to the □
position using the MA key which is kept by the store manager. Then enter
each item just as in the normal registering operation made in the "REG"
mode. The □ position of the Mode Lock processes the entered items
exactly in the reverse way, i.e,, positive items into negative, and
negative into positive.
The positive total balance resulted in the □ mode indicates the amount
to be refunded to the customer.
RECEIPT POST-ISSUE (Mode Lock: REG) (Allowed only outside a sale)
[RECEIPT ISSUE] . A receipt with the total amount of the last-finalized
sale is issued. The system option provides the
selection not to issue the post-receipt if the last
sale has been finalized with the [RECEIPT ON/OFF]
switch postitioned to 'ON'.
