Section 1 — First-Time Setup
Complete these steps immediately after installation before handing to users
Before You StartEnsure the board is connected to a stable network (Wi-Fi 5GHz or Ethernet preferred). Do not skip the firmware update step — many performance issues are caused by outdated firmware.
Initial Power & Firmware Update Required
1
First BootPower on the display. Allow the Android launcher to fully load before proceeding (30–60 sec).

Section 2 — Display & System Settings
Key settings to eliminate lagginess, slow wake-up, and animation delays
Root Cause of LagMost WAF performance complaints (lag, slow wake, sluggish touch) are caused by animation scales set too high, unnecessary background apps, energy saving mode throttling CPU, and auto-sleep settings conflicting with active sessions.

Section 3 — Network Configuration
Correct network setup is critical for casting, screen sharing, and software updates
Best PracticeUse a wired Ethernet connection for the board wherever possible. If Wi-Fi only, always connect to 5GHz band — 2.4GHz causes most of the lag and dropout complaints seen with casting.
🔌 Ethernet Setup (Recommended)
1
Connect LAN CablePlug into the RJ45 port on the board. The board auto-detects.
2
Verify ConnectionSettings → Network → Ethernet
Ensure IP is assigned and speed shows 100Mbps or 1Gbps.

📶 Wi-Fi Setup (If Ethernet Not Available)

Connect to 5GHz NetworkSettings → Network → Wi-Fi
Select the 5GHz SSID (usually labelled _5G or _5GHz). Avoid 2.4GHz.
Select the 5GHz SSID (usually labelled _5G or _5GHz). Avoid 2.4GHz.
2
Check Signal StrengthThe board should be within 5–8 metres of the AP for stable casting. Walls reduce signal — request AP placement near meeting room if needed.
3
Assign a Static IP (Optional but Recommended)Set a DHCP reservation or static IP so the board is always discoverable at the same address.
🔐 Network Ports & Firewall Notes IT Team
Ensure the following are not blocked by corporate firewalls for full functionality:
Casting (Miracast/WiDi): Devices must be on the same subnet/VLAN as the board.
Samsung Remote Management: Allow outbound HTTPS (443) to Samsung DMS cloud.
Software Updates: Allow access to Samsung update servers.
Note: If guest devices on a separate VLAN need to cast, configure VLAN bridging or use USB-C/HDMI cable as fallback.

Section 6 — Troubleshooting
Quick-fix reference for the most common WAF issues reported by users
| Symptom | Likely Cause | Fix |
|---|---|---|
| Board is laggy / slow touch response | High animation scales; too many background apps; Power Saving mode |
1. Set animation scales to 0.5x (see Section 2)2. Settings → Device Care → Optimise Now3. Set Power Mode to Optimised4. Restart the board |
| Screen takes long to wake up | Sleep timer + slow Android wake cycle |
1. Press physical power button on front panel (fastest wake) 2. Reduce screen timeout to 30 min3. Check: Settings → Display → Screen Saver → Off4. If persistent, do a restart cycle |
| Casting keeps disconnecting | Weak Wi-Fi; device on different VLAN; board sleeping during cast |
1. Move casting device closer to AP 2. Ensure both on same network/VLAN 3. Disable screen timeout during presentations 4. Try USB-C or HDMI cable as immediate workaround |
| Casting not found / board not visible | Different subnet; Miracast/AirPlay not enabled; wrong input source |
1. Confirm board is on Home screen (not HDMI input) 2. Open Samsung Wireless Sharing app on board3. Check both devices on same Wi-Fi network 4. Restart Samsung Wireless Sharing app |
| Casting is laggy / stuttering video | 2.4GHz Wi-Fi; network congestion; high screen resolution |
1. Switch laptop Wi-Fi to 5GHz band2. Lower display resolution on casting device to 1080p 3. Close other apps on the casting device 4. Use USB-C cable for video-heavy content |
| Touch does not work properly | Dirty screen; palm rejection conflict; touch firmware bug |
1. Clean the screen with microfibre cloth 2. Ensure no liquids or wet hands on screen 3. Remove and re-attach pen if dual-pen mode is in use 4. Restart the board |
| App crashes or freezes | Insufficient RAM; corrupted cache; outdated app |
1. Settings → Apps → [App] → Force Stop2. Clear app cache: Settings → Apps → [App] → Storage → Clear Cache3. Update app via Galaxy Store or Play Store 4. Restart board |
| No sound from board speakers | Source muted; HDMI input mute; wrong output |
1. Check volume using physical button or on-screen control 2. If on HDMI input: check source device volume 3. Settings → Sound → Sound Output → Internal Speaker4. Test with Samsung Note app pen sound |
Last Resort: Factory ResetIf the board remains unusable after all above steps, perform a factory reset via
Settings → General → Reset → Factory Data Reset. Ensure all Note files are exported and backed up first. Contact Kubernex support before proceeding.Section 7 — Preventive Maintenance Schedule
Recommended routine to keep the board performing well long-term
Daily
After Each Session
- Close all open apps before leaving
- Export and save whiteboard notes
- Wipe screen with dry microfibre cloth
- Return to home screen
- Allow board to sleep (don't force power off)
Weekly
Every 5–7 Days
- Run Device Care → Optimise Now
- Clear storage cache
- Check for app updates (Galaxy Store)
- Verify Wi-Fi / network connectivity
- Full restart of the board
- Wipe screen with slightly damp (not wet) cloth
Monthly
Once a Month
- Check firmware update availability
- Review and disable unused apps
- Inspect physical ports (dust, debris)
- Check pen tips — replace if worn
- Test all casting methods (Android, iOS, Windows)
- Log any recurring issues for follow-up
🌡️ Environmental Best Practices
- Ventilation ClearanceMaintain at least 10cm clearance around all sides of the board. Do not mount in enclosed cabinets without ventilation.
- Avoid Direct SunlightStrong sunlight on the panel causes overheating and affects touch sensitivity. Use blinds if needed.
- AC TemperatureOperate in 16–30°C environment. Overheating causes thermal throttling — the main hidden cause of lag in Singapore rooms.
- Pen StorageStore pens in the pen tray when not in use. Do not leave pens with tips on the screen (activates touch continuously).
- Screen CleaningUse only a dry or slightly damp microfibre cloth. No alcohol-based sprays — they damage the anti-glare coating over time.
