Solving Problems with the RIHM

If you leave the RIHM unused for a long time, the power of the battery might get to a critical level that the RIHM cannot be used.  You should prevent his by charging the RIHM in time. You can leave the RIHM to be charged overnight without problems.

If you cannot get the RIHM working, try to recharge the battery in an ordinary penlight battery recharger.
