Battery Charging Precautions
Thinklabs One Digital Stethoscope is powered by an internal rechargeable Lithium
Ion battery. Lithium Ion batteries power many devices today - mobile phones,
tablets, medical devices. However, they must be handled properly to ensure safe
use. Please take the following seriously to avoid injury, fire or explosion:
● We have tested One with the included USB Charger. We cannot guarantee
the safety of charging One with other USB chargers.
● If One becomes hot while charging, disconnect immediately and allow it to
cool. Do not move One while it is cooling. Contact Us immediately if One
warms up during charging.
● Charge One at ambient temperatures between 5C-35C (41F - 95F). If the
battery temperature is out of range, a safety circuit may shut off charging
until the battery temperature falls within an acceptable range.
● Disconnect the Charger from the AC Mains or from the stethoscope once
charging is complete.
● Do not attempt to open or replace the battery.
● If your stethoscope fails to charge, Contact Us.
