Troubleshooting
Q
Every transaction that I take is producing a referral, am I doing
something incorrectly?

Mobile terminals require a good mobile network signal in order to
operate, if you are in an area that mobile phones do not operate
then the terminal will, also, not operate. You should move to an
area of good mobile network signal. If no mobile network is shown
on the screen then you should check that the SIM is installed
correctly. You should refer to the section entitled SIM Card
Installation for further details. If the problem persists you should
contact the terminal Helpdesk.

Bluetooth terminals require either a telephone line or LAN in order
to operate. You should check that the base unit is connected
correctly and that the telephone line or LAN are working correctly.
You should refer to the sections entitled Base Overview and PSTN
& Ethernet Connectivity for further details. If the problem persists
you should contact the terminal Helpdesk. If there is a problem with
the telephone line or internet connection you should contact your
telecommunications supplier.
Q
My totals on the Z Balance and Banking reports do not match, what
do I do?

The Z Balance report totals give you a total of all transactions done
across all acquirers. The Banking report totals give you the total for
each acquirer. You should try to add up all the individual totals
across all acquirers on the Banking to try to reconcile with the Z
Balance total. The current session totals on the Banking shows all
transactions for that session - if you perform the Z Balance and
Banking at the same time every trading day this should match the
totals on the Z Balance. If you still cannot match the totals you
should contact the terminal Helpdesk. Please ensure that you have
all relevant reports with you when you call. It is possible that you will
be asked for the proceeding day's reports as well.
Q
A number of contactless transactions prompt that the card should be
inserted or swiped, is this normal?

It is routine that a contactless card will require a further security
check occasionally. If the card is used for a lot of contactless
transactions then this should be expected.
Q
How do I adjust the contrast of the screen? (iWL221 & iWL222 only)

While the terminal is displaying the idle screen press and hold the
dot key and the down or up keys for at least 5 seconds.
