How do I care for and charge my batteries?

Keep the battery clean and free of dirt and grime.
Do not drop/damage or crush medical instrument or battery
Do not allow medical equipment near fire or flame
Do not allow children to handle medical equipment or batteries
Do not use in wet or damp conditions

To extend the life of your battery:

Discharge fully once a month. To fully discharge the battery...Turn on the otoscope and leave for several hours. When the bulb in the otoscope is no longer "Lite", turn off the otoscope and place it in the charging unit overnight.
Fully recharge for 16 hours. Do not leave it in the charging unit all day and night; charge the battery in the otoscope overnight and remove it in the morning for use. DO NOT set back in charging unit between daily use or battery will be damaged and warranty will be voided. Use only in appropriate medical equipment handles

CAUTION: Many times failure of the battery to charge is a direct result of charging unit failure, not charging the battery for 16 hours before use, or leaving it in the charging unit all day or night. Remove the otoscope from the charging unit in the morning and do not replace it in the charging unit until the end of the work day.
