4. Operating the Device
4.1 Real-time Tracking
The Winnes Mini 4G GPS Tracker TK901 offers real-time tracking through SMS commands or a dedicated mobile application/web platform.
4.1.1 SMS Tracking
To get the device's location via SMS, send the command "G123456#" to the tracker's phone number. The tracker will reply with an SMS containing a Google Maps link to its current location. This method also provides battery status and device ID.

See Video 1 from 1:05 to 1:36 for a demonstration of SMS tracking.
4.1.2 App Download and Login
For a more interactive tracking experience, download the "WINNES GPS" app from your smartphone's app store (Google Play Store for Android, Apple App Store for iOS). Once installed, log in using the device ID (found in SMS replies) and the default password "123456".

The app can be downloaded from http://www.mytkstar.net/download.htm.
A visual guide for app download and login is available in Video 1 from 1:36 to 2:04.
4.1.3 Continuous Tracking
Within the app's real-time tracking interface, you can activate continuous tracking to receive updated location data at regular intervals. You can also switch between map views (e.g., satellite, street map) and view the distance to your device.
Refer to Video 1 from 2:04 to 2:49 for details on real-time tracking features.
4.2 Historical Route Playback
The app allows you to view the device's historical routes for up to the last 6 months. Select the desired start and end times to review the movement history.
See Video 1 from 2:49 to 3:09 for a demonstration of historical route playback.
4.3 Geo-fencing
Set up virtual boundaries (geo-fences) in the app. You will receive an alarm message when the device enters or exits these predefined areas. This feature is useful for monitoring specific zones like home or work.

4.4 Alerts and Notifications
The device can send various alerts to your phone via the app. It is recommended to keep the default notification settings and enable all notifications for comprehensive monitoring.
- Vibration Alarm: Enable this to receive alerts when the device detects movement or vibration. After parking for 5 minutes, if the device senses vibration (e.g., car restart), an alarm is sent. Note: If the device is already in motion, it will detect vibration but no alarm will be sent.
- Low Battery Alarm: Notifies you when the battery level is low.
- Overspeed Alarm: Alerts you if the device exceeds a set speed limit.
- SOS Alarm: Triggered by pressing the SOS button (if available on the model).
- Moving Alarm: Alerts when the device starts moving after being stationary.
For enabling the Vibration Alarm, refer to Video 1 from 3:28 to 3:41. For general notification settings, see 4:15 to 4:24.
4.5 GPS Work Mode Settings
You can configure the GPS working mode to balance tracking frequency and battery consumption. Higher frequency provides more accurate historical routes but consumes battery faster.
- Real-time Mode: Updates location frequently (e.g., every 30 seconds).
- Power Saving Mode: Updates less frequently (e.g., every hour).
- Standby Mode: Updates even less frequently (e.g., every 24 hours).
- Custom Upload Interval: Allows you to set a specific interval (e.g., 10-3600 seconds).
To set the GPS working mode, refer to Video 1 from 3:09 to 3:28.
5. Maintenance
5.1 Charging the Battery
Use the provided USB cable to charge the device. Connect the cable to the tracker and a standard 5V-1A USB power adapter. A full charge typically provides 24-48 hours of active use or up to 200 hours in standby mode.
5.2 General Care
- Waterproof: The device is designed to be waterproof, but avoid prolonged submersion or exposure to high-pressure water jets.
- Magnetic Attachment: The strong magnet allows for convenient installation on metal surfaces. Ensure the device is securely attached to prevent accidental detachment.

- Temperature: Operate and store the device within recommended temperature ranges to ensure optimal battery life and performance.
- Cleaning: Clean the device with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
6. Troubleshooting
6.1 Device Not Online / No Location Data
- Check SIM Card: Ensure the Nano SIM card is correctly inserted, has an active data plan, and its PIN code is disabled.
- APN Configuration: The Access Point Name (APN) must be correctly configured for your SIM card's network provider.
- Search online for your SIM card provider's APN settings.
- Insert the SIM card into a mobile phone and find the APN settings in the phone's network settings.
- Network Coverage: Ensure the device is in an area with good 4G network coverage.
- Battery Level: A low battery can affect connectivity. Charge the device fully.
To find your SIM card's APN:
To set the APN via SMS, send the command: apn123456 [APN Name] (e.g., apn123456 mobile.vodafone.it for Vodafone Italy). Replace "123456" with your device's password if changed from default. After receiving an "apn ok" reply, remove and reinsert the SIM card to restart the device.
Refer to Video 1 from 4:24 to 4:53 for a visual guide on APN setting via SMS.
6.2 Inaccurate Location
- GPS Signal: Ensure the device has a clear view of the sky for optimal GPS signal reception. Indoor or underground locations may result in LBS (Location Based Service) tracking, which is less precise.
- Working Mode: Check the GPS work mode settings in the app. Real-time mode provides the most frequent and accurate updates.
6.3 Short Battery Life
- Tracking Frequency: High tracking frequency (e.g., 30-second updates) consumes more battery. Adjust the GPS work mode to a longer interval (e.g., power saving or standby mode) to extend battery life.
- Network Signal: Poor network signal can cause the device to consume more power searching for a connection.
- Charging: Ensure the device is fully charged before use.
