When using a touchscreen cash register, please pay attention to the following points to ensure its normal operation:
When shutting down, follow the normal procedure. Do not directly unplug the power cord or turn off the power without exiting the system. **The proper shutdown procedure must be followed to avoid damage to the equipment.**
Before powering on, carefully check that the power cord is firmly plugged in. If it is loose, make sure to plug it in securely before powering on. Follow the correct power-on sequence: first turn on peripheral devices (such as printers, customer displays, etc.), then start the main unit. **Check the power cord before powering on and ensure the correct sequence to ensure normal operation of the equipment.**
If the touchscreen cash register becomes unresponsive for an extended period due to a program error or other reasons, press and hold the power switch for five seconds to force shutdown, but do not directly unplug the power switch. When the equipment malfunctions and becomes unresponsive, press and hold the power switch to force shutdown, rather than unplugging the power cord.
Cashiers are strictly prohibited from hitting the touchscreen or main unit with hard objects during use. Only use your fingers to lightly touch the touchscreen, and avoid using fingernails or other objects (such as magnetic cards) to touch the touchscreen. Any form of impact with hard objects will cause damage. Following these guidelines, restaurants may consider touchscreen cash registers when choosing a system, as they are more convenient than physical button cash registers. However, careful operation is essential to ensure stable functioning of the cash register.
