- ON/OFF Button: Powers the device on or off.
- A/C Weighted Button (A/C): Selects A-weighting or C-weighting frequency response.
- Battery Cover: Access to the battery compartment.
- Backlight Button: Activates or deactivates the LCD backlight.
- LEVEL Switch Buttons (Up/Down Arrows): Adjusts the measurement range.
- MAX/MIN Button: Displays maximum or minimum measured values.
- HOLD Button: Freezes the current reading on the display.
- Calibration Hole: Used for manual calibration of the device.
4. Setup
4.1 Installing Batteries
The Tadeto TE017 requires three 1.5V AAA batteries. To install:
- Locate the battery cover on the back of the device.

5. Operating Instructions
5.1 Power On/Off
- Press the ON/OFF button to turn the device on.
- Press and hold the ON/OFF button for a few seconds to turn the device off.
5.2 Selecting Measurement Range (LEVEL)
The device offers 5 adjustable measurement ranges for optimal accuracy. Use the LEVEL up/down arrow buttons to cycle through the ranges:
- 30-80dB
- 30-130dB
- 50-100dB
- 60-110dB
- 80-130dB
Select the range that best suits the expected noise level to ensure the most accurate readings.

5.3 A/C Weighting Selection
Press the A/C button to switch between A-weighting and C-weighting modes.
- A-Weighting: Simulates the frequency response of the human ear at low sound levels. Ideal for environmental noise detection.
- C-Weighting: Provides a flatter frequency response, suitable for measuring high-intensity noise, such as from machinery or motors.
5.4 Fast/Slow Response Rate
Press the F/S button to select the desired response rate.
- FAST (0.125s): For general environmental measurements where noise levels change rapidly. Provides a more sensitive reading.
- SLOW (1s): For environments with relatively stable noise levels or to average out fluctuating sounds. Provides a more stable reading.

5.5 MAX/MIN Measurement
Press the MAX/MIN button to view the maximum or minimum sound level recorded during the current measurement session.
- Press once to display the maximum value (MAX).
- Press again to display the minimum value (MIN).
- Press a third time to return to real-time measurement.
5.6 Data Hold
Press the HOLD button to freeze the current reading on the LCD display. Press it again to release the hold and resume real-time measurement.
5.7 Backlight
Press the Backlight button to turn the LCD backlight on or off, improving visibility in low-light conditions.
5.8 Audible and Visual Alarms
The device features audible and visual alarms. If the measured sound level exceeds a certain threshold (typically the upper limit of the selected range), the device may emit an audible alert and/or flash the display to indicate an over-range condition.
6. Maintenance
6.1 Cleaning
Wipe the device with a soft, dry cloth. Do not use liquid cleaners or solvents, as they may damage the casing or internal components. Keep the microphone clean and free from obstructions.
6.2 Battery Replacement
