Note: When an IMR with a fully discharged battery is connected to power via its USB cable,
it may display a white battery error indicator. This is normal behavior while a fully discharged
battery is charging to a minimum voltage, at which time it should follow the states shown in
the Power indicator LED table. Wait several hours while the battery charges and you should
eventually see the power LED turn solid red, indicating it is charging, and finally solid green,
indicating that it is fully charged and ready for use. If the white LED never turns off while the
IMR is connected to power, the battery is likely bad and must be replaced. This will need to be
done approximately every 300 to 500 charge cycles. See Installing a Replacement
Battery on page 33.
