Welcome to the Thinklabs Community
Congratulations! You now own the revolutionary Thinklabs One - an electronic
stethoscope like no other. Welcome to the Thinklabs Community of clinicians,
researchers, educators and students who believe in quality in everything they do.
Quick Reference Guide
Design - Thinklabs One is designed with form and function intended for an era of
compact, efficient design; a stethoscope for the age of digital music and instant
communication. The design hides advanced technology and an elegantly simple
form.
Amplification - With over 100X amplification compared to a typical acoustic
stethoscope, One's small form hides an extraordinary power to reproduce heart
sounds with the punch of a rock drummer or a hip-hop track.
Audio Filter System - Multiple filters give you control over the sound with far
more nuance than the blunt instrument of a "bell" or "diaphragm". You can also
limit bandwidth to exclude ambient noise.
Rechargeable Battery - A Lithium Ion battery gives you the battery life you
need in a compact device. Charging is made convenient and easy, using a
standard USB style charger.
Patented Transducer - Thinklabs has built its reputation on technology that
maintains the timbre and tactile sense of an acoustic instrument, with the clarity
and power of electronics.
Connectivity - Thinklink gives you connection to almost any device you're likely
to use for recording, telemedicine, communication, teaching or research. Use
mobile phones, tablets, computers, digital audio recorders.
Support - Owning a Thinklabs is a mark of those who take medicine seriously.
We take our service to you as seriously.

Optimal Use of Your Thinklabs One Digital Stethoscope
Instructions - Your Thinklabs One Digital Stethoscope has been designed to be
very easy to use. However, if you take the time to learn the deeper features of
your stethoscope, you will probably use it more effectively.
Sound Levels - Thinklabs One can be set to very loud volume levels. Don't make
your stethoscope volume louder than necessary. Adjust volume so that heart and
lung sounds are clear and comfortable to listen to. Protect your hearing!
Diaphragm Pressure and Skin Contact - Making skin contact will provide you
with the best sound quality. If you do listen through clothing, avoid listening
through thick garments.
Headphone Fit - Make sure your headphones are as sealed as possible against
outside noise. This will enhance your own listening. Use Thinklabs headphones or
equivalent high quality headphones.
Battery Charge - Remember to charge your battery. Your Thinklabs One will
give you many warnings to recharge your battery and it is designed to have
enough charge for only one or two charge cycles a week.

Battery Charging
Thinklabs One Digital Stethoscope is powered by an internal rechargeable Lithium
Ion battery. A USB-style charger is included with your One stethoscope. Your One
will usually be shipped to you with a partial charge. You should charge it fully
before using it clinically. A full charge should provide over 4 hours of listening.
Before you charge your stethoscope, read these Battery Charging
Precautions before you proceed.
To charge your stethoscope:
1. Connect the Charger Cable 3.5mm plug to your One, disconnecting
headphones if they are plugged in. The Charger Cable is a white cable with
3.5mm phone and USB plug on each end, respectively.
2. Connect the USB plug to the USB Charger. Use only the charger supplied with
One - it has been tested and qualified to be safe for use with your stethoscope.
Other USB chargers will charge your One, however we cannot guarantee their
operation.
3. Connect the charger to an AC Mains outlet. The charger is a worldwide charger
(100-240V, 50/60Hz). In some countries, you may require a plug adapter.
4. When charging, the Battery LED will flash. As the battery charges, the flash
rate will slow. When the battery is fully charged, the LED will be On and stop
flashing. A thorough charge cycle can take as long as 8 hours, however your One
will have almost full capacity within 4 hours. To check the battery level, see the
Battery Level Indication section.

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.
For more information, go to Battery Charging Instructions.
