The instrument has a protection feature which works when nickel hydride batteries are overcharged
or when the batteries are under a high or low temperature (+70°C or higher, or 0°C or lower) state.
In such a case, charging will stop automatically to protect nickel hydride batteries.
Recharging should be performed in a room temperature ranging from +10°C to +40°C.
Always use the AC/DC converter provided with the product.
1) The Ni-MH BT-67Q rechargeable battery can be charged while using the laser.
2) The Ni-MH BT-67Q rechargeable battery can be charged when the battery holder is
removed from the instrument. This allows the option of alternately using two battery
packs to always maintain a fully charged pack.
3) The Ni-MH BT-67Q rechargeable battery can be removed from the DB-75C battery
holder and 4
×D size dry cell batteries (alkaline) can be installed.

battery pack. Use the DB-75C charging battery holder instead.
