What to do if my Riken Keiki Microphone displays a low flow rate alarm [FAIL LOW FLOW]?
- C
  Caroline WilliamsSep 12, 2025
  If your Riken Keiki Microphone displays a low flow rate alarm, it could be due to several reasons. First, check the gas sampling hose for any damage or signs of water or oil being drawn in. Second, inspect the gas sampling hose for any blockages, clogs, or twists. If the gas monitor was powered on at a low temperature or hasn't been used for a while, try cycling the power several times to see if the pump starts operating. If none of these steps work, the pump may have deteriorated, and you should contact RIKEN KEIKI to replace it.

What to do if the batteries of Riken Keiki Microphone cannot be charged (Lithium ion battery unit only)?
- M
  Michelle SavageAug 23, 2025
  If the batteries of your Riken Keiki Microphone aren't charging (Lithium ion battery unit only), first, make sure the AC plug and DC plug of the AC adapter are properly connected. If that doesn't resolve the issue, there may be a charging circuit abnormality, and you should contact RIKEN KEIKI for repair. Also, keep in mind that if the batteries are already fully charged, the charging indicator lamp won't turn on when you try to charge them again.

  Mr. Douglas MyersAug 28, 2025
  If communication errors occur with your Riken Keiki Monitor, it might be due to scattered infrared light interference. Try eliminating any devices emitting IR light in the vicinity. Also, avoid moving the RX-8500/8700 main unit during communication to prevent errors.

Why communication is not possible with Riken Keiki Monitor?
- K
  Karen GrantAug 30, 2025
  If communication with your Riken Keiki Monitor is not possible, the main unit's position might be inappropriate. Try adjusting its position. Alternatively, another device using infrared (IR) might be interfering. Turn off other IR devices or prevent their interference.

What to do if the Riken Keiki Gas Detectors reading rises and remains?
- J
  johnsondorothySep 1, 2025
  If the reading on your Riken Keiki Gas Detectors rises or drops and remains at that level, it could be due to several reasons. First, try performing an air calibration, as the sensor output may be drifting or environmental changes may be affecting the reading. Check for any interference gases, like solvents, and address them accordingly. Also, consider the possibility of a slow gas leak. If a leak is suspected, take immediate action as you would during a gas alarm. The oxygen sensor is particularly sensitive to air pressure, so air calibration may help.

Why won't my Riken Keiki Gas Detectors turn on?
- R
  Ray AdamsSep 3, 2025
  If your Riken Keiki Gas Detectors won't turn on, the battery level may be too low, or the battery unit might not be installed correctly. If you're using a dry battery unit, replace all three batteries with new ones in a safe place. If it's a Li-ion battery unit, charge it in a safe place. Also, ensure the battery unit is properly attached to the main unit.
