Charging Cable or the Ring Case Charger.
The magnetic pins auto-align, and the LED indicator lights up to confirm
charging and show battery status.
Slow white breathing (up to 20 seconds) = Charging | Solid white = Full
charge
2. Wear the Ring
Remove the ring from the charger. Place on your right or left index finger,
whichever feels more natural. Make sure the trackpad is facing the thumb at the
bottom, and the Modstrip is on top.
3. Automatic Power-On
The ring powers on automatically when removed from the charger — no button
needed.

Air Gesture Trigger (Pro Edition)
Air gestures are available on Pro Edition only.
How to trigger Air Gestures
1. Tilt your finger so the charging port is at the bottom of the ring.
2. When the ring detects the correct orientation, the 3 LEDs turn on (●●●) to
indicate Air-Ready.
3. While Air-Ready is on, perform an air gesture with strong acceleration and
deceleration (a quick, deliberate motion).
4. When an air gesture is recognized, the 3 LEDs flicker briefly to confirm the
gesture was triggered.
5. Supported air gestures:
o Air-swipe left
o Air-swipe right
o Air click (single click)
o Air double-click
6. Left-hand use: enable Left-Handed Settings in Prolo Studio to use air
gestures on the left hand.
Tip: If the 3 LEDs do not turn on, adjust the tilt angle until the charging port points
down more clearly.

Palm Hold
Lock (Requires Unlock Gesture or Charging to Unlock)
Palm Hold is a natural gesture for moments when you’re taking off the ring—or
when you want to quickly lock it to prevent accidental inputs for a short time.
To unlock, simply single tap + press-and-hold on the ModStrip, or place the ring
back onto the charger. When locked, 1x Tap + Press & Hold performs Unlock only
(no device switching).
For longer breaks, we recommend removing the ring and storing it on the charger.
Note: Customizable gestures are available only with Pro Edition and above.

5. SYSTEM COMMANDS
The Prolo Ring uses standard Bluetooth HID and does not require any drivers or
software for basic operation.
Automated First-Time Pairing
1. Remove the ring from the charger or touch the trackpad to wake it.
2. Open Bluetooth Settings on your device and search for:
“Prolo Ring”
3. Select it to connect.
LED Behavior
• Slow triple-blink = Ring is in pairing / advertising mode (discoverable)
• Connecting chase (1→2→3 sweep repeating) = Ring is trying to connect /
switching hosts
• Solid 3 LEDs for 2 seconds (●●●) then off = Successfully connected
System Commands on the Modstrip (Tap + Hold)
System commands are performed on the Modstrip.
Tap Preview (Bar Pattern)
• With each tap, the LED bar grows: 1 → 2 → 3
• For 4–5 taps, the bar wraps but becomes more obvious:
o 4 taps = 1-bar noticeably brighter
o 5 taps = 2-bar noticeably brighter
When the tap count is reached, press & hold the Modstrip to execute the command.
Success & Abort Rules
• Success confirmation: all 3 LEDs fast triple-strobe (3x)
• Abort conditions:
o Any touchpad touch cancels the pending command
o No press-and-hold detected within 2 seconds from the last tap
• Abort indication: Down-sweep (3→2→1), then off
1x Tap + Press & Hold – Connect / Switch / Unlock
This is your main Bluetooth control gesture.
Gesture:
• 1 tap + press & hold on the Modstrip
Behavior:
• If the ring is not connected
o The ring will try to reconnect to the last used host (A).
o If it cannot connect after a short search, it stops.
• If the ring is already connected to a host (A)
o The ring will auto-search and switch to the next remembered device
(B, C, …) and try to connect.
o If no other device responds, it reverts to A.
• If you repeat the gesture within 10 seconds of the last connect attempt
o The ring enters auto-search and switch mode, cycling through other
remembered devices in order.
o when a connection succeeds:
▪ LED: 3 LEDs solid for ~2 seconds to confirm the new host.
LED during operation:
• Tap preview: 1-bar
• While searching/connecting: Connecting chase (1→2→3 sweep repeating)
• On success: 3 fast-strobes (all LEDs) + 3 LEDs solid ~2s
Tip: The ring remembers multiple bonded hosts (e.g., laptop, tablet, phone) and lets
you roam between them using just this one gesture.
2x Tap + Press & Hold – Add a New Device (Pairing)
Use this when you want to pair the ring with a new host (e.g., a new laptop or
phone).
Gesture:
• 2 taps + press & hold on the Modstrip
LED:
• Tap preview: 2-bar
• While waiting: slow triple-blink (pairing)
• On success: 3 fast-strobes (all LEDs) + 3 LEDs solid ~2s
Behavior:

• LED: pairing pattern (slow triple-blink) while it waits for a new connection.
Important:
Before adding a new device, please disable Bluetooth or disconnect the ring from
any devices it’s already paired and connected to.
This prevents existing hosts from “stealing” the connection while you are trying to
pair a new one.
Then, on the new device:
1. Open Bluetooth Settings
2. Select “Prolo Ring”
3. Wait for the LEDs to show 3 solid bars for ~2 seconds to confirm pairing.
The ring stores up to 3-5 previously paired devices depending on the edition.

7. CUSTOMIZATION WITH PROLO STUDIO
Prolo Studio Introduction
Unlock advanced features with Prolo Studio, available for Windows, macOS, and
Linux.
You can map gestures to shortcuts, control media, launch apps, or build complex
macros — all from one interface.
Download Prolo Studio: proloring.com/downloads
(Prolo Studio customization features require the Pro Edition.)
Device Status & App Status
Prolo Ring operates in two distinct statuses to support both universal compatibility
and advanced features.
Device Status (Default)
Device Status is the standard operating status of the Prolo Ring.
• Works on all devices using Bluetooth HID
• No software required
• Provides all built-in gestures, cursor control, media control, and motion
features
• Behaves like a universal mouse/remote
• Ideal for laptops, desktops, tablets, phones, smart TVs, projectors, VR, and
more
Use Device Status whenever you want instant pairing, plug-and-play control, or
when you’re using a computer where installing apps is restricted (school, office,
shared workstations).
App Status (For Advanced Features)
App Status activates when the ring connects directly to Prolo Studio on your
computer.
In this mode, the Studio app becomes a “translator,” converting customized
gestures into advanced commands.
In App Status, you can:
• Fine-tune sensitivity, LEDs and Bluetooth transmission power
• Save configurations back to the ring
• Access gesture animation previews and real-time diagnostics
For Pro Editions, you can also:
• Create & switch multiple profiles instantly
• Build complex macros
• Insert key sequences, combos, or automation chains
• Launch applications
Important:
• App Status requires the Prolo Studio app running in the background
• Only one ring can be actively registered with the Studio app at a time
• The ring must manually switch into App Status using a gesture.
Switching Between Status
Toggle Device Status / App Status:
• 3x Tap + Press & Hold on the Modstrip
