Q: Can't receive alarm notifications on the APP
A: 1. APP have to be running in background on Android system. No need for background on iOS.
2. Check the settings of your cellphone and make sure the cellphone allow the APP send notifications.
Q: Can I keep the tracker constantly under charge through the car electrical system?
A: Yes, you can use it for temporary use, but it is not recommended as the device would highly be worn out.
Q: In sleep mode, will the device keep the GPS and its functions on?
A: No. Call the device or send the command G123456# and it will be 100% operative again.
Q: Can I receive alarm SMS on two different phones?
A: Yes, you can add a second phone number as SOS number on the APP to receive double alarm SMS.
Q: Position is different from the actual position.
A: No uploading position time or no GPS signal: call the device to receive the position message. If it shows
like Pic 2, it means no GPS signal. The position is the last GPS positioning location, not the real-time position;
If it shows like Pic 1, it means the device doesn't reach the uploading time. (If GPS uploading time interval is
1 hour, it will send GPS position once one hour)
