User guide

elcome to duō, a compact handheld
sales and payment device for the Retail
and Hospitality industries. Until now, no
convenient portable solution has offered
Point-of-Sale and multiple secure payment technologies in
one device. The unique two-sided architecture allows sales
to be entered on one side, and payments processed on the
other. Separating the two core functions ensures that the
Point-of-Sale side remains open-architecture, whereas the
payment side remains compliant to nancial (PCI) standards.

Cautions
Before operating duō, read and understand all instructions in this booklet.
• Do not look straight into the emitting laser barcode scanner. Class 2 laser
scanners use a low power visible light diode. As with any very bright light source,
such as the sun, avoid staring directly into the beam. Momentary exposure to a
Class 2 laser is not known to be harmful.
• Do not use this equipment in an extreme environment where high temperature
or high humidity exists.
• Do not abuse the equipment. Avoid striking, shaking or giving it a shock. When
not using the unit, lay it down or place in the recharge cradle to avoid possible
damage due to instability.
• Do not expose this equipment to rain or spilled beverages.
• Avoid charging the Battery in strong heat or extreme cold environment. The
battery has its optimum performance in an ambient temperature of 0°C to
+45°C. Do not store the Battery near a re or heat source. Never soak the
Battery in water or any other uid. Never try to open the Battery as it contains
substances that may be harmful if swallowed or allowed to come into contact
with unprotected skin. Never short-circuit the Battery, as it may overheat and
cause a re. Keep it away from jewellery and other metal objects. Never dispose
of the Battery in a re. It could explode and release harmful substances into the
environment. Never dispose of the Battery with your regular waste.
• Do not disassemble duō or its accessories. If service or repair is required,
contact your place of purchase to organise for the unit to be returned. If the unit
is disassembled this will void the warranty and tamper the device rendering it
inoperable.
