Screen flicker may indicate voltage instability, display driver malfunction, or electromagnetic interference (EMI). App crashes can be linked to software bugs, memory leaks, or API conflicts with the payment processing software. The EMV chip reader and NFC antenna are susceptible to ESD (electrostatic discharge) during low-humidity conditions. Baud rate mismatch is unlikely but a potential culprit if the device has been improperly reconfigured.
Do NOT attempt to open the Clover Station casing. Doing so will void the warranty and may trigger anti-tamper mechanisms, rendering the device unusable. Ensure the device is placed on a stable, dry surface. Avoid spilling liquids near the device. If the device is visibly damaged or emits smoke/odors, disconnect it immediately and contact Clover support. Do NOT use near flammable materials.
Regularly clean the touchscreen with a recommended cleaner. Ensure adequate ventilation around the Clover Station to prevent overheating. Route power cables away from other electronic devices and potential sources of EMI. Consider using a surge protector to protect against power fluctuations. During dry winter months, use anti-static wrist straps when handling the device to mitigate ESD.
Try performing a 'soft reset' by simultaneously pressing the power button and the volume down button for 10 seconds. This can sometimes resolve minor software glitches without erasing data. Ensure that the Scotiabank Clover app is compatible with the current OS version of the Clover Station.
