12 • Introduction Sam4POS Operators Manual v2.33
Sam4POS Power Requirements
Plug the Sam4POS terminal into a grounded 3-prong outlet. It is recommended to have dedicated branch circuits for the
Sam4POS equipment and isolated grounding for all equipment in the system.
• Be aware that other electrical devices on the same circuit can cause your Sam4POS to malfunction. Avoid
plugging your Sam4POS into outlets where other high-current devices are connected.
• Be aware that power quality issues, including voltage fluctuations, electrical noise, spikes, outages,
interruptions, and other power viruses can disrupt or damage modern electronic equipment, including
Sam4POS terminals and PCs.
• When Sam4POS is interconnected in networks, connected to PCs or where communications cables
connect peripherals, particular care must be taken with power sources and communication cable routing.
Your authorized dealer can provide detailed power specifications for these applications. Failure to
implement installation requirements for networked systems may cause system failures and/or poor system
performance.
Safe Operation
• Do not locate your SAM4s Sam4POS in a damp or wet environment. Avoid high humidity, direct sunlight
and temperature extremes.
• Always plug your Sam4POS into a grounded three-prong outlet. Never use two-prong adaptors or
ungrounded outlets.
• Check to make sure the power outlet provides the correct voltage: (120V +/- 10%).
• Immediately disconnect the Sam4POS from the power source in case of spilled liquid in the Sam4POS,
smoke, or strange smells. Call your authorized dealer for assistance.
• Do not operate the Sam4POS with wet hands.
• Use a soft dry cloth to clean the Sam4POS cabinet. Do not use wet clothes or solvents.
• Do not open the Sam4POS case to attempt repairs. Dangerous voltages can cause shock. Service attempts
by untrained personnel can cause unnecessary damage to your terminal.
