All topics
• Stethopod unit with the round touch screen
• Chestpiece with the cable to the unit
• Wired earphones (3.5 mm)
• USB-C charging cable
1. Plug the USB-C cable into any 5 V USB charger or a computer.
2. The side LED is red while charging and green when full. About 2 hours from empty.
3. Left alone on charge, the screen shows the battery percentage.
You can keep using the stethoscope while it charges.
1. Wake: press the upper side button (SW1) once, or touch the screen.
2. Sleep: hold SW1 for 3 seconds. Sound stops, the screen goes off, the blue LED pulses slowly. Bluetooth stays reachable for the app.
3. The unit sleeps by itself after 1 minute without being moved. Pick it up or double-tap it to wake it; sound starts again by itself. It does not sleep while charging.
1. Wake the unit. The home screen shows the current mode word, for example Bell.
2. Put in the wired earphones or your paired earbuds.
3. Place the chestpiece. The sound is live with no delay you can notice.
Nothing on the screen moves while you listen, so nothing distracts.
Tap one of the three icons on the top arc, press SW1 once to cycle, or choose the mode in the app.
• BELL 40 to 150 Hz. Low-pitched sounds.
• DIA 90 to 1000 Hz. Breath sounds and higher-pitched sounds.
• EXTD 10 to 1200 Hz. The full range, closest to the raw chestpiece.
1. Drag your finger along the rim of the screen, clockwise to increase.
2. The ring fills one step every 34 degrees. There are 8 steps; the app shows the same range as 5 levels.
3. At the top the ring stops. It never jumps back to zero, so a long drag is safe.
The ring fades 1.5 seconds after you lift your finger.
• Mute: drag anticlockwise along the rim past step 1, press the lower side button (SW2) once, or tap mute in the app.
• Unmute: tap the centre of the screen, press SW2, drag clockwise, or tap mute again in the app. The previous level comes back.
The mode word stays on screen while muted so you know the filter has not changed.
Tap NC in the bottom bar of the device, or use the Noise reduction switch in the app. Extra microphones in the unit listen to the room and subtract it from the chestpiece sound.
Use it in a noisy classroom or lab. In a quiet room leave it off; very faint sounds come through cleaner without it.
Plug any 3.5 mm earphones into the jack. Wired output is always on while the plug is in.
1. Tap the headphone icon in the bottom bar to open Output, or use the Output section in the app.
2. Bluetooth ON sends the sound to LE Audio earbuds as well as the wired output. OFF saves battery on long shifts.
3. Auracast only turns the wired output off and broadcasts to any Auracast receiver nearby.
1. Put your earbuds into their pairing mode.
2. Open Output and tap Pair new earbuds (or Pair earbuds in the app). The unit is visible for 60 seconds.
3. Choose Stethopod on the earbuds if they ask.
Earbuds must support Bluetooth LE Audio. Auracast earbuds can also join the broadcast without pairing.
1. Switch on Bluetooth on the phone and wake the Stethopod.
2. In the app tap Connect Stethopod. The Devices tab scans and lists your unit; tap Connect.
3. The Stethoscope tab shows the live sound, mode, volume, output and noise-reduction controls, and the battery level.
Changes made on the device screen appear in the app and the other way round.
By default any phone with the app can connect to a Stethopod, control it and receive its sound.
1. To keep it to yourself: on the device open Phone and tap Allow new phone. In the app, on the Stethoscope tab, choose Only me under Who can connect within 60 seconds. The phone and the Stethopod then both show a 6-digit number: if the two numbers are the same, tap Pair on the phone and Yes on the Stethopod. If they differ, or the Stethopod shows a number while your phone shows none, tap No: another phone is trying to pair. After No, or if the pairing does not finish, tap Allow new phone again and repeat. Your phone is now an owner and the device shows Owner only.
2. From then on other phones are refused. Your phone reconnects by itself.
3. To add another phone, tap Allow new phone on the device again and connect that phone within 60 seconds, comparing the 6-digit number in the same way. Up to 3 phones are remembered.
4. To open it again choose Anyone in the app, or tap Owner only on the device so it reads Open to all.
5. Device code: once you are an owner, set a 4-digit code under Who can connect. The Stethopod then asks for it on its screen before Open to all, Allow new phone or Forget phones work, so someone who finds the unit cannot open it up or add a phone. Five wrong tries lock the code for a minute. You can change or remove the code from your phone at any time.
6. Forgot the device code and no owner phone left: on the keypad tap forgot code?. The Stethopod waits 10 minutes for a reset. Open the app signed in to the account the unit belongs to, connect, and use Reset the device code by email. If your phone has to pair, compare the 6-digit number on the phone and on the Stethopod and confirm on both. Then we email you a 6-digit code, and the reset removes the device code and all other owner phones and makes your phone the owner. A unit is bound to your account when your phone is its owner and you are signed in and online; the app shows when this is set up. A unit that was never bound cannot be reset this way.
A phone can only pair and become an owner while Allow new phone is open on the device, and only after you confirm its 6-digit number on the device screen. Forget phones on the device removes all owner phones.
This setting covers the phone link only. Earbuds and Auracast listeners follow the Output setting: switch Bluetooth output off to stop broadcasting.
Tap "Try the demo" on the sign-in screen, or the "Try the demo" card on the Home screen if you are already signed in, to use the app without a Stethopod. On the Devices tab, "No Stethopod? Try the demo" does the same.
• The Stethopod tab shows a simulated device: change the mode, volume and route, watch the live waveform, play the sound on the phone and record a clip.
• The Recordings screen holds two sample clips (a heart sound in Bell and a breath sound in Diaphragm) that you can play, annotate and share; your own demo recordings join them.
• Remote listening, invitations and alerts need an account and are not available in the demo.
To leave, open Profile and tap "Exit demo". If you were signed in, you stay signed in. Nothing from the demo is sent anywhere.
1. With the sound running, tap GO LIVE. The app shows a 6-digit code.
2. Tell the code to the other person, or invite a saved contact by their Stethopod ID.
3. On their phone they open Listen Remotely and enter the code.
4. Tap STOP SHARING when done. The live sound is relayed in real time and is not stored on our servers.
1. Tap the dot (REC) in the bottom bar. The screen asks for a name or number for the entry. Only the room microphone is heard and recorded, at full bandwidth, until you tap the MIC button (or REC). Up to 1 minute.
2. Tap MIC. The chestpiece takes over and the clip records with the timer in red.
3. Tap REC to save. The screen shows Saved with the entry number.
Hold REC to discard. Clips are stored on the device as numbered WAV files.
1. With the sound running on the Stethoscope tab, tap REC. Tap again for the voice note, and again to save.
2. Open Recordings on the home screen to play, share or delete entries. They stay on the phone; nothing is uploaded by us.
1. Swipe up from the home screen to open Display.
2. Drag along the rim for brightness, in 5 steps, or tap Dark / Light for the theme. The same settings are in the app under Device screen.
After 20 seconds without a touch the backlight drops to the lowest step; after 60 seconds more the screen turns off. Any touch brings it back.
The small battery under the mode word shows the charge; a bolt next to it means charging.
An amber triangle means something needs you: chestpiece cable not detected, battery at 10 %, or device storage full. Tap to dismiss.
• SW1 (upper), press: wake the screen; when awake, cycle DIA, BELL, EXTD.
• SW1, hold 3 s: sleep.
• SW2 (lower), press: mute or unmute.
• SW2, hold about 15 s: hardware restart. Use only if the screen is frozen.
• Wipe the chestpiece and the housing with a cloth dampened with 70 % isopropyl alcohol between uses.
• Clean the glass with a soft dry cloth. No abrasive pads.
• Do not immerse, autoclave or spray liquid into the jack or the USB-C port.

1. In the app open Profile and tap Delete account and data.
2. Confirm. Your account, profile, contacts, invitations and notification token are removed from our servers within 7 days, and the app signs out.
3. Recordings on the phone or on the device are yours and are not touched.
