  Kara HallAug 2, 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.

  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.
