Replacement Steps

• Ensure your hands and device are dry; prevent static discharge.

Battery Step 1

• Place the device face down on a stable, dry surface with connectors pointing down.

Battery Step 2

• Partially unscrew 6 back-panel screws until the panel can be lifted off (keep screws in place).

  • Tip: Loosen screws manually before using an electric screwdriver.

Battery Step 3

• Remove back panel and place flat-side down.

  • Warning: Do not remove the rubber gasket; it is thin and not glued.

Battery Step 4

• Switch ON/OFF on interface board to OFF.

Battery Step 5

• Disconnect old battery connector; mark old battery as Used and dispose of properly.

Battery Step 6

• Mark the new battery with the current date. Connect it to the interface board.

  • Wavelet 4R: Green LED blinks (1 long + 1 short) x 3 times.

  • Other models: Green, red, and blue LEDs blink briefly (connection confirmed).

Battery Step 7

• Switch ON/OFF back to ON.

  • Device performs a 10-minute calibration and resumes normal mode.

Battery Step 8

• Replace back panel:

  • Ensure battery cable is not pinched.

  • Ensure gasket is in place (missing gasket voids water/dust damage coverage).

Battery Step 9

• Tighten 6 screws to 1 Nm torque.

  • Do not over-tighten to avoid stripping threads.

• Reset battery status:

  • UI Option:

    • Devices → Select Device → Actions → Reset Battery Life

    • OR Fleet → Select Device → Set Action → Reset Battery Life

  • AyyekaGo App:

    • Connect → More → Reset Battery Life

The device is now ready to resume normal operations.
