2. Powering On/Off:

   Press and hold the MODE button for a few seconds to power on the device. To power off, press and hold the MODE button again until the display turns off.

3. Satellite Acquisition:

   For accurate readings, the device needs to acquire satellite signals. Place the device outdoors with a clear view of the sky. The GPS icon on the display will indicate signal strength. Wait until the icon is solid, indicating a stable connection.

4. Mounting:

   Use the included dashboard mount or other suitable mounting solutions to securely attach the device to your RC model. Ensure the device is positioned to have an unobstructed view of the sky.

Operating Instructions

The GSM-015 features two main buttons: MODE and ENTER.

• MODE Button: Short press to cycle through different display modes (e.g., current speed, peak speed, altitude, total distance). Long press to power on/off the device.
• ENTER Button: Used to confirm selections or reset certain values (e.g., reset peak speed or total distance).

Display Modes:

• Current Speed: Displays your real-time speed.
• Peak Speed: Shows the highest speed recorded during the current session. Press ENTER to reset.
• Altitude: Displays your current elevation.
• Total Distance: Tracks the cumulative distance traveled. Press ENTER to reset.
• GNSS Status: Indicates satellite signal strength and connection status.

Data Logging and PC Link

The GSM-015 can record data which can then be transferred to a computer for analysis using the SKYRC GNSS LOGGER software. This software is compatible with Windows 7 and above, and macOS 10.12 and above.

1. Software Installation: Download and install the SKYRC GNSS LOGGER software from the official SKYRC website.
2. Connect to PC: Connect the GSM-015 to your computer using the micro USB cable.
3. Data Transfer: Open the GNSS LOGGER software. The software will detect the device and allow you to transfer logged data. You can view your tracks on maps (e.g., Bing Maps) and analyze various parameters.
4. Settings and Firmware: The software also allows you to change settings such as measurement units, time zone, and perform firmware updates.

Measurement Systems

The device supports both Metric and Imperial systems of measurement. To switch between them, short press the MODE button until you reach the settings menu (if available, or refer to the software for more advanced settings). Alternatively, this setting can be changed via the GNSS LOGGER software on your computer.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Do not use harsh chemicals or solvents.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: For optimal battery life, avoid fully discharging the battery frequently. Charge the device regularly, especially if storing for extended periods.
• Water Resistance: The device is not waterproof. Avoid exposure to water or high humidity to prevent damage.

Troubleshooting

Device does not power on:

Ensure the battery is charged. Connect to a USB power source and try again. If the issue persists, the battery may need replacement.

No satellite signal / Inaccurate readings:

Ensure the device has a clear, unobstructed view of the sky. Avoid using it indoors or near tall buildings/dense foliage. Allow sufficient time (several minutes) for initial satellite acquisition.

Display is dim or unreadable:

Check battery level. The device does not have a backlight, so ensure adequate ambient lighting for readability.

Data transfer to PC fails:

Ensure the USB cable is securely connected to both the device and the computer. Verify that the SKYRC GNSS LOGGER software is correctly installed and updated. Try a different USB port or cable.

Battery drains quickly:

Battery life is approximately 150 minutes. If it drains significantly faster, the battery may be aging or faulty. Ensure the device is fully charged before use. Extreme temperatures can also affect battery performance.
