# Vision Modes Explained

## Edge/Thermal, Thermal, Edge, Edge/Hotspot, Triple Overlay — when to use each.

### **Overview**

The C-THRU Navigator offers **five vision modes** designed for different conditions and personal preference.

Each mode combines thermal and edge-detection layers to enhance awareness in low-visibility environments.

---

### **Vision Modes Summary**

| **Mode** | **Display Type** | **Best For** | **Description** |
| --- | --- | --- | --- |
| **Edge/Thermal** | Combined outline and thermal overlay | Most environments | Default mode. Shows heat sources with structural edges. |
| **Thermal** | Full thermal view | Heavy smoke or zero visibility | Emphasizes heat contrast for locating fire or victims. |
| **Edge** | Wireframe outline only | Orientation, non-heated environments | Simplifies structure and obstacles. |
| **Edge/Hotspot** | Edge outline with highlighted heat points | Hotspots, fire spread, overhaul | Hot items marked by colored overlay. |
| **Triple Overlay** | Edge + Thermal + Hotspot | Complex conditions | Full augmented composite for maximum detail. |

### **Switching Modes**

- Tap the **Vision (V)** button once to toggle sequentially through modes.
- Long-press to enable or disable the **laser pointer**.
- Mode preference is stored per session; reset on reboot.

---

### **Tips for Use**

- Use **Edge/Thermal** for interior navigation and search.
- Switch to **Thermal** when tracking heat sources or victims.
- Avoid over-reliance on the HUD; maintain situational awareness through direct observation and crew communication.
- If the HUD image becomes white-out or distorted, allow 5–10 seconds for the camera to recalibrate as it adjusts from cool to hot environments.

### **Troubleshooting Vision Issues**

| **Issue** | **Likely Cause** | **Action** |
| --- | --- | --- |
| No image in HUD | Misaligned HUD or connection loss | Re-adjust HUD or reseat cable. |
| Fogging or soot buildup | Dirty HUD lens or facepiece | Wipe HUD, projector lens, and SCBA facepiece. |
| White-out | Rapid temperature change | Wait for camera to auto-adjust gain. |

### **Maintenance Note**

Wipe the **HUD, projector, and camera lenses** after every use. Keep the lenses dry, avoid abrasives, and store the device in a clean environment.

### **Safety Reminder**

- Each mode is a **tool for awareness**, not a replacement for fundamentals.
- Always confirm visual data with physical search and standard tactics.
