Recharging
the North 5000 requires following the specific instructions for its battery
type. Begin by opening the battery compartment to check if the battery is
correctly placed according to the polarity indicated inside. If not, adjust the
battery accordingly. Close the compartment and connect the respirator to a
power outlet using its original charger. The charging process might take
several hours, depending on the battery's capacity and current level. It's
crucial to disconnect the device once it's fully charged to prevent
overcharging, which can reduce the battery's lifespan.
