RotaryCell / build guide

Test your RotaryCell

Repeat a brief check after the case is fitted. Closing the telephone can shift a wire, affect the perceived audio level or reveal interference that was not obvious while the dial was raised.

Final checklist

  • Incoming call and bell ringing
  • Outgoing call and rotary dialing
  • Hook operation and two-way audio
  • On battery with USB disconnected, service code 9999 completes the hardware power cycle and the phone restarts
  • Maintenance Wi-Fi starts and the browser page is reachable
  • Charging works with the documented USB-A-to-USB-C cable
  • Battery operation and battery-voltage reporting
  • Connectors remain seated and the wiring has strain relief
  • The closed case leaves the bell, dial and switch-hook mechanism unobstructed
