• Which Tingrui manuals are available here?

  Available documentation includes the K2 Wake Up Light instruction manual and CH09 Radio Night Light Alarm Clock user manual. Match the model on your device to the manual before following instructions.

• How do I set the time on the K2 or CH09?

  Press and hold the Time Set button for two seconds. Rotate the Snooze control to select the time format, hour, minute and day, pressing Time Set to confirm each selection.

• Can the K2 operate on its backup battery alone?

  No. The K2 manual states that AC power is required. Its CR2032 battery only preserves settings during a power failure.

• How do I pair the K2 with my phone?

  Hold the BT button for two seconds, enable Bluetooth on your phone and select K2 from the device list. Bluetooth supports audio playback, not remote control of the clock's other functions.

• How do I activate the warranty or get support?

  The supplied manuals mention a lifetime warranty and recommend contacting the provider with your order number to activate it. No verified support address or registration page is available here; check your included documentation or ask your seller to confirm the terms and contact details.
