What to do if Riken Keiki Monitor shows low battery voltage alarm?
If your Riken Keiki Monitor displays a '' message, it means the battery level is low. To resolve this, turn off the power and charge the battery in a safe place where the ambient temperature is between 0 °C and +40 °C.
Why does Riken Keiki GX-3R turn off immediately after turning on?
If your Riken Keiki Monitor turns off immediately after you turn it on and displays '', the battery level is likely too low. Turn off the device and charge the battery in a safe place at temperatures between 0 °C and +40 °C.
What to do if Riken Keiki GX-3R shows abnormal operation?
If your Riken Keiki Monitor is behaving abnormally, it might be due to interference from static electricity or other noise. Try turning the power off and then back on again to see if that resolves the issue.
Why Riken Keiki Monitor triggers gas alarm with no gas leak?
If a gas alarm is triggered on your Riken Keiki Monitor when there's no apparent gas leak, it could be due to interference gases or noise. Interference gases are difficult to completely eliminate. Another potential cause is noise. Try turning the power off and then back on again. If the issue persists, investigate and address potential noise sources.
Why Riken Keiki GX-3R charge LED flashes green and orange?
If the charge LED on your Riken Keiki Monitor flashes alternately green and orange, it indicates that the temperature is outside the allowable charging range. Make sure you are charging the device where the ambient temperature is between 0 °C and +40 °C.
Why Riken Keiki Monitor reading rises or drops and remains unchanged?
If the reading on your Riken Keiki Monitor rises (or drops) and remains unchanged, it could be due to sensor drift, presence of interference gases, slow leakage of the detection target gas, or environmental fluctuations. You can try performing air calibration to address sensor drift or environmental fluctuations. For interference gases, it is difficult to completely eliminate their effects. For slow leakage, take the same action as for gas alarms.
