4.1. LED Indicators
- GPS Status LED: Indicates GPS signal acquisition. Blinks when searching for satellites, solid when a fix is obtained.
- Bluetooth Status LED: Indicates Bluetooth connection status. Blinks when discoverable/pairing, solid when connected.
- Battery Status LED: Indicates battery charge level and charging status.
5. Setup
5.1. Charging the Device
- Connect the mini USB charging cable to the Mini USB port on the side of the BT-Q818XT (refer to Figure 4.2).
- Connect the other end of the USB cable to a USB power adapter (not included) or a computer's USB port.
- The Battery Status LED will indicate charging. A full charge typically takes several hours.
- Once fully charged, the Battery Status LED will change its indication (refer to the full LED guide in the appendix, if available, or device specifications).
5.2. Powering On/Off
To power on the device, slide the switch on the side (refer to Figure 4.3) from 'OFF' to either '1Hz' or '10Hz'. To power off, slide the switch to 'OFF'.
5.3. Bluetooth Pairing
To connect the BT-Q818XT to a compatible Bluetooth-enabled device (e.g., Android smartphone, Windows laptop):
- Ensure the BT-Q818XT is powered on and within range of your host device.
- On your host device, enable Bluetooth and search for new devices.
- Select 'Qstarz BT-Q818XT' (or similar name) from the list of available devices.
- If prompted for a passcode, enter '0000' (four zeros).
- Once paired, the Bluetooth Status LED on the BT-Q818XT will typically become solid, indicating a successful connection.
5.4. Connecting to a PC (GPS Mouse Mode)
The BT-Q818XT can function as a wired GPS receiver when connected to a computer via its Mini USB port. This requires installing the appropriate drivers and software from the Qstarz website. Once installed, the device will provide GPS data directly to your computer's applications.
6. Operating
6.1. GPS Signal Acquisition
After powering on, place the BT-Q818XT in an open area with a clear view of the sky. The GPS Status LED will blink as it searches for satellites. Once a sufficient number of satellites are acquired for a position fix, the GPS Status LED will become solid. This process may take longer for a cold start (first use or after a long period of inactivity).
6.2. Selecting Update Rate (1Hz / 10Hz)
The BT-Q818XT features a hardware switch to select the GPS update rate:
- 1Hz Position: Provides one GPS position update per second. This mode conserves battery life and is suitable for general navigation.
- 10Hz Position: Provides ten GPS position updates per second. This mode offers higher precision for applications requiring rapid position changes, such as performance tracking. Note that using 10Hz mode will consume battery power more quickly. Also, in 10Hz mode, differential GPS (like WAAS) may be disabled, potentially affecting absolute accuracy but improving tracking of relative changes.
6.3. Using with Navigation Software
Once the BT-Q818XT is paired via Bluetooth and has acquired a GPS fix, open your preferred navigation or mapping application on your host device. The application should automatically detect the external GPS receiver and begin using its data for positioning.
7. Maintenance
7.1. Cleaning
Wipe the device with a soft, dry cloth. Do not use liquid cleaners or solvents, as they may damage the device's surface or internal components.
7.2. Storage
When not in use for extended periods, store the device in a cool, dry place. It is recommended to charge the battery periodically (e.g., every 3-6 months) to maintain its health.
7.3. Battery Care
The BT-Q818XT uses a Lithium Ion battery. To prolong battery life, avoid fully discharging the battery frequently and avoid leaving it fully charged or fully discharged for very long periods in extreme temperatures.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Battery is depleted. | Charge the device using the Mini USB cable. |
| No GPS signal fix. | Device is indoors or obstructed. | Move the device to an open outdoor area with a clear view of the sky. |
| Bluetooth pairing fails. | Incorrect passcode or device not in pairing mode. | Ensure the device is powered on. Re-enter passcode '0000'. Restart both devices. |
| GPS data not received by application. | Application settings or incompatibility. | Check your application's settings for external GPS support. Ensure the BT-Q818XT is paired and has a GPS fix. |
| Device not recognized by PC. | Missing drivers. | Install the necessary drivers from the Qstarz official website. |
