Troubleshooting a Verifone VEGA3000 displaying 'AC Loss'. Includes voltage checks, cable inspection, ESD prevention, and safe handling procedures.
Check the device's label or the power adapter for the voltage and polarity.
Use anti-static mats, grounding straps, and control humidity when possible.
Contact Verifone directly or an authorized Verifone distributor.
The VEGA3000 uses a DC power supply converted from AC mains. The device monitors the input voltage. A voltage drop below a specific threshold triggers the 'AC Loss' message. High ESD (Electrostatic Discharge) events can temporarily disrupt the power management IC. Poor cable connections increase resistance, dropping voltage.

Safe Handling: Always unplug the VEGA3000 from the power outlet before inspecting cables or connectors. Do not use excessive force when connecting or disconnecting cables. Never operate the device with damaged cables. Ignoring these steps can result in electric shock or equipment damage.
Regularly inspect power cables for damage. Avoid cable strain by ensuring adequate slack and proper routing. In dry environments (especially during winter), use anti-static mats and sprays to minimize ESD events. Clean the device casing with a dry cloth only.
If the 'AC Loss' message appears intermittently, try a different AC power outlet known to be on a stable circuit. External EMI (Electromagnetic Interference) from nearby devices could be a contributing factor. Relocating the VEGA3000 slightly, or adding a ferrite choke to the power cable may reduce interference.
