Buyers must prioritize wireless transmission technology, typically choosing between 2.4GHz RF (Radio Frequency) for better range and obstacle penetration or Bluetooth (BLE) for smartphone app integration. Ensure the PCB layout supports the specific motor configuration of the bed (e.g., head-only, head-and-foot, or massage functions). Additionally, verify the standby power consumption is low to extend battery life and that the backlight functionality uses energy-efficient LEDs for nighttime visibility.
