Battery care
• Do not fully exhaust the rechargeable battery.
• Only store instrument with battery charged and at low temperatures, but not
below 0°C (best storage conditions with a charge level of 50-75% = 2
segments, at an ambient temperature of 10-20°C, recharge completely
before use).
• The rechargeable battery life depends on the storage, operating and
ambient conditions. The available useful life of the rechargeable battery
reduces more and more with frequent use. If the useful life is significantly
shortened, the rechargeable battery should be replaced.
