3. Setup

3.1 SIM Card Installation

The TK918 tracker requires a 4G SIM card for communication. You can use the SIM card provided with the device, which may require a subscription, or use your own local 4G SIM card that supports SMS, calls, and internet access. Ensure the SIM card is active and has sufficient balance/data plan.

1. Locate the SIM card slot on the device.
2. Insert the 4G SIM card into the slot with the correct orientation.
3. Ensure the SIM card is securely seated.

3.2 Charging the Device

Before first use, fully charge the TK918 tracker. The device has a built-in 20,000mAh battery. Connect the tracker to a power source using the provided charging cable. The charging indicator light will show the charging status.

3.3 Device Activation

Once the SIM card is installed and the device is charged, power on the tracker. The device will automatically connect to the network. You can then access the tracking features via the dedicated mobile application or web platform.

4. Operating Instructions

The TKMARS TK918 offers a user-friendly interface compatible with both Android and iOS systems, as well as a web platform.

4.1 Real-time Tracking

Track the device's location in real-time on Google Maps through the mobile application, SMS commands, or the computer web platform. The minimum data upload interval is 10 seconds. The device uses GPS+LBS dual positioning, providing 5-10 meters accuracy in GPS mode and 100-2000 meters in LBS mode.

4.2 Historical Route Playback

The tracker records and stores historical route data for up to 6 months, allowing you to review past movements of the tracked asset.

4.3 Geofence Alerts

Set up customizable geofence boundaries on the map. You will receive an alert notification if the tracker enters or exits these predefined areas.

4.4 Alarm Functions

The TK918 provides multiple alarm functions for enhanced security:

• Shock Sensor Alarm: Notifies you if unauthorized movement or tampering is detected.
• Motion Alarm: Alerts you if the device starts moving.
• Speed Alarm: Sends an alert if the tracked vehicle exceeds a preset speed limit.
• Fall Off Alarm: Notifies you if the device is accidentally removed or dropped.
• Low Battery Alarm: Alerts you when the battery level is low, prompting a recharge.

4.5 Voice Monitoring

You can listen to the sounds around the device by calling the SIM card number within the tracker from your mobile phone. This feature provides an additional layer of security and monitoring.

4.6 Sleep Modes

The TK918 features intelligent sleep modes to conserve battery life:

• Sleep by Time Mode: After this setting, the tracker will only work for 5 minutes after being woken up, then return to sleep mode. GPS will shut off, and GSM will operate in low consumption mode. SMS or calls can wake up the tracker.
• Sleep by Shock Sensor Mode: If no shock is detected for 5 minutes, the tracker will enter "sleep by shock" mode. GPS will shut off, and GSM will operate in low consumption. Vibration, SMS, or calls can wake up the tracker.

5. Installation

The TK918 GPS tracker is designed for easy, free installation thanks to its strong built-in magnets.

1. Identify a suitable metal surface on your vehicle or asset, such as under a seat, in the luggage compartment, or on the chassis.
2. Ensure the surface is clean and dry for optimal magnetic adhesion.
3. Simply place the tracker onto the metal surface. The strong magnets will securely attach the device.

For best GPS signal reception, avoid placing the device in enclosed metal containers or areas with heavy metal shielding.

6. Maintenance

• Charging: Recharge the device when a low battery alert is received. Regular charging ensures continuous operation.
• Water Resistance: The TK918 is rated IP67 waterproof, meaning it is protected against dust and can withstand immersion in water up to 1 meter for 30 minutes. While durable, avoid prolonged submersion or exposure to high-pressure water jets.
• Cleaning: Clean the device with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
• Storage: Store the device in a cool, dry place when not in use for extended periods.

7. Troubleshooting

If you encounter issues with your TKMARS TK918 GPS Tracker, consider the following:

• No Signal/Offline:
  • Check if the SIM card is correctly installed and activated.
  • Ensure the SIM card has sufficient balance or data plan.
  • Verify that the device is in an area with good 4G network coverage.
  • Move the device to an open area to improve GPS signal reception.
• Inaccurate Location:
  • GPS accuracy is typically 5-10 meters. LBS mode (when GPS is unavailable) has lower accuracy (100-2000 meters).
  • Ensure the device is not obstructed by heavy metal structures or indoors, which can degrade GPS signal.
• Battery Draining Quickly:
  • Check the tracking frequency settings in the app; more frequent updates consume more power.
  • Ensure the device is fully charged.
  • Utilize the sleep modes (Sleep by Time or Sleep by Shock Sensor) to extend battery life.
• Device Not Responding:
  • Try restarting the device.
  • Ensure the battery is charged.
