Beep (only for models with an MSR)
The beeper can be enabled or disabled with the MSR utility. If
enabled, the beeper sounds once for a successful card reading and
three times for an unsuccessful card reading.
Operation
Adjusting the View Angle
The tilt mechanism of the LCD monitor allows you to adjust it to a
comfortable viewing angle.
Hold both sides of the display and adjust the angle as shown in
illustration J.
How to Read a Magnetic Stripe Card
Slide the card through the slot with the magnetic stripe facing
down.
The MSR can read the data whether the user slides the card from
left to right or right to left, as shown in illustration K.
Do not stop sliding the card during the reading of data. This may
cause a read error.
Do not use the keyboard while the MSR is reading a card.
When magnetic card data has a header or footer, make the proper
settings with the MSR utility.
Display Adjustment
To adjust the LCD display, use the On-Screen Display (OSD) menu.
To adjust the OSD menu with the Function buttons, use the
