2BVIL-R1Prolo Ring

PROLO RING USER MANUAL COVER PAGE Prolo Ring The All-in-One Ring Mouse Controller 1. OVERVIEW Inside the Box • Prolo Ring • Ring Charging Cable • Quick Start Guide • Ring Sizing Adjuster • Ring Case Charger* • Ring Case Charging Cable* Device Overview 1. Trackpad Zone – Thumb surface for cursor and click control. 2. Modstrip – Top touch strip for mode switching and shortcuts. 3. 6-Axis Motion Sensor – Enables Air Mode motion gestures. 4. LED Indicator – Displays power, Bluetooth, and mode status. 5. Charging Pads – Magnetic connectors for charging (inside). 2. QUICK SETUP 1. Before First Use Charge the Prolo Ring fully before first use. Charge using either the Ring 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. 4. Pair via Bluetooth Open Bluetooth Settings on your device and select “Prolo Ring.” 3 LEDs Solid for ~2 seconds = connected. 5. Start Controlling Prolo Ring starts with the cursor mode or the last functional mode. 3. MODES AND GESTURES Prolo features three control MODES: Cursor Mode, Touch Mode, and Air Mode. Each mode includes two gesture sets: Standard (default) and Modified (for advanced or macro actions). The modes and gesture sets are selected/toggled using Modstrip and Trackpad. Quick Mode Reference Mode Set Name Use How to Enter Cursor Standard Mouse & Cursor control Swipe Left on Modstrip Modified (Navigation) Navigation & zoom Swipe Right on Modstrip Touch Standard Media & shortcut control Swipe Right + Hold Modstrip Modified (ModTouch) Macro layer Hold Modstrip in Touch Mode Air Standard Motion control Swipe Left + Hold Modstrip Modified (AirTouch) AirTouch layer Hold Trackpad in Air Mode Cursor Mode Standard Gestures — Cursor and scrolling.

Mod Hold + Swipe Up / Down Customizable* Mod Hold + Tap / Double Tap / Triple Tap Customizable* Air Mode Standard Set — Control without touching any surface. Swipe Left / Right Customizable* Air Click Customizable* Air Double-Click Customizable Modified Set — Hold the Trackpad while in Air Mode. Hold + Swipe Left / Right Customizable* Hold + Air Click Customizable* Hold + Air Double-Click Customizable 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. System & Mode Switch Action Use Modstrip to trigger the following system actions. Swipe Left Enter Cursor Mode (Standard) Swipe Right Enter Navigation Set (Cursor Modified) Swipe Right & Hold Enter Touch Mode Swipe Left & Hold Enter Air Mode 1x Tap + Press & Hold Connect / Switch / Unlock 2x Tap + Press & Hold Enter Pairing to Add a New Device 3x Tap + Press & Hold Toggle Device Status → App Status 4x Tap + Press & Hold Shutdown (Requires Charging to Wake Up) 5x Tap + Press & Hold Reset to Factory Default 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. 4. BUILT-IN FUNCTIONS These core functions work instantly after pairing — no app required. Works across all major systems (Windows, macOS, Android, iOS, Linux). Cursor Control • Move Cursor • Left / Right / Middle Click • Click-and-Drag / Drag-and-Drop Navigation • Page Up / Down • Scroll Up / Down • Arrow Left / Right • Pan Left / Right • Pinch In / Out (Zoom) Media Control • Camera Shutter • Volume Up / Down • Next / Previous Track • Fast Forward / Rewind • Play / Pause • Mute 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.

The minimum amount of solder can lead to damage from the stresses caused by the difference in coefficients of expansion between solder, chip and substrate. The terminations are suitable for all wave and re-flow soldering systems. If hand soldering cannot be avoided, the preferred technique is the utilization of hot air soldering tools. Recommended temperature profiles for re-flow soldering in Figure 1. Products attachment with a soldering iron is discouraged due to the inherent process control limitations. In the event that a soldering iron must be employed the following precautions are recommended. ‧Preheat circuit and products to 150°C ‧Never contact the ceramic with the iron tip ‧Use a 20 watt soldering iron with tip diameter of 1.0mm ‧280°C tip temperature (max) ‧1.0mm tip diameter (max) ‧Limit soldering time to 3 sec.
