5. Tatūnga
5.1. Tāuta Pūhiko
The Mastfuyi FY8862 requires two AAA 1.5V batteries. To install or replace batteries:
- Kimihia te uhi pākahiko kei muri o te taputapu.
- Use a small Phillips head screwdriver to unscrew the battery cover.
- Insert two AAA 1.5V batteries, ensuring correct polarity as indicated inside the compartment.
- Whakakapihia te uhi o te pākahiko ka mau ki te huri.
5.2. Whakatau
The device is factory-calibrated. If recalibration is necessary, follow these steps:
- Pehia te PURU/REKE pātene me te Whakawhiti Mana button simultaneously. Hold the PURU/REKE pātene.
- After the device powers on, briefly press the Whakawhiti Mana button. The screen will display "MAX" to indicate entry into calibration mode.
- Set your standard signal source device to 94dB.
- Align the decibel meter to the standard signal source device. Wait for the meter reading to stabilize at 94dB.
- Pehia te PURU/REKE button to save the calibration.
- Pehia te Te Hiko / Whakaweto button to restart the device. Calibration is now complete.
6. Nga Tohutohu Whakahaere
