IMPORTANT!
Alkaline batteries cannot be recharged. The instrument’s internal
circuit detects alkaline batteries and will not allow recharging. If you
place the instrument in its Travel Charger or Charger Stand, the
alkaline battery will not be recharged. The internal charging circuit is
designed to prevent damage to alkaline batteries and the charging
circuit when alkaline batteries are installed inside the instrument. If
you try to charge an alkaline batteries installed in the instrument, the
Charging Cradle or Travel Charger’s charging LED does not glow,
indicating that it will not charge the alkaline batteries.
Note:
When replacing alkaline batteries, dispose of old ones properly.
