5. Setup
5.1 Battery Installation
- Locate the battery compartment cover on the back of the device.
- Slide or unclip the cover to open the compartment.
- Insert 3 x AAA batteries (not included) according to the polarity indicators (+/-) inside the compartment.
- Replace the battery compartment cover, ensuring it is securely closed.
5.2 Initial Power-On
After installing batteries, the device is ready for initial power-on.
6. Operating Instructions
6.1 Powering On/Off
- To Power On: Press and hold the red power button (ⓘ) until the device powers on and the display illuminates.
- Warm-up Time: The device will display "WAIT..." and undergo a warm-up period of approximately 30 seconds. During this time, avoid exposing the sensor to gas.
- To Power Off: Press and hold the red power button (ⓘ) again until the device shuts down.
6.2 Gas Detection Process
- Once the warm-up is complete, the device is ready for detection.
- Direct the flexible probe's sensor tip towards the area where a gas leak is suspected.
- Slowly move the sensor tip around the suspected area.
- Observe the LED analog bar display and listen for the audible alarm.

6.3 Interpreting the Display and Alarms
- LED Analog Bar: The illuminated segments on the LED bar indicate the concentration level of detected gas. More segments lit up signify a higher concentration.
- Audible Alarm: The device will emit an audible alarm when gas is detected, with the frequency or intensity increasing with higher gas concentrations.
- Visual Alarm: The LED display also serves as a visual alarm, complementing the audible alert.

6.4 Sensitivity Adjustment
Use the 'Lo', 'Mid', and 'Hi' buttons to adjust the detection sensitivity according to your needs. 'Hi' provides the highest sensitivity for detecting small leaks, while 'Lo' is for larger concentrations or less sensitive detection.
6.5 Automatic Reset
The HT601A features an automatic reset function, which means the device will automatically recalibrate or clear its alarm state once the gas concentration returns to a safe level, without requiring manual intervention.

6.6 Automatic Shutdown
The device is equipped with an automatic shutdown feature (indicated by √ in specifications) to conserve battery life. Refer to the specifications for the exact duration before automatic shutdown.
7. Maintenance
7.1 Cleaning
- Wipe the exterior of the device with a soft, dry cloth.
- Do not use abrasive cleaners or solvents, as they may damage the casing or internal components.
- Keep the sensor tip clean and free from dust or debris to ensure accurate readings.
7.2 Storage
- When not in use, store the gas detector in its provided storage bag to protect it from dust and physical damage.
- Store in a cool, dry place, away from direct sunlight and extreme temperatures.
- Remove batteries if the device will not be used for an extended period to prevent leakage.
7.3 Battery Replacement
When the battery undervoltage indication appears on the display, replace the 3 x AAA batteries following the installation steps in Section 5.1.
8. Troubleshooting
If you encounter issues with your Naroote HT601A, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Dead or incorrectly installed batteries | Replace batteries with new ones, ensuring correct polarity. |
| No gas detection or inconsistent readings | Sensor not properly positioned, warm-up not complete, or sensor tip is dirty | Ensure warm-up is complete. Position sensor tip directly at the suspected leak source. Clean the sensor tip if necessary. |
| False alarms | Interference from other substances or high background gas levels | Ensure the detection area is clear of other potential gas sources. Adjust sensitivity to a lower setting if appropriate for the environment. |
| Audible alarm not working | Alarm muted or device malfunction | Check if the speaker icon button has been pressed to mute the alarm. If not, contact support. |
