Frequently asked questions
What is T23 ?
T23 is the only tracking device that uses easy to understand landmarks to show it’s location. The location is determined by GPS satellites and you use a regular GSM phone to send and receive text messages from your T23. It is NOT a navigation device, but instead helps you keep your family, friends and assets safe.
What is GPS ?
The Global Positioning System, usually called GPS, is the only fully-functional satellite navigation system. A constellation of more than two dozen GPS satellites broadcasts precise timing signals by radio, allowing any GPS receiver to accurately determine its location (longitude, latitude, and altitude) in any weather, day or night, anywhere on Earth. GPS has become a vital global utility, indispensable for modern navigation on land, sea, and air around the world, as well as an important tool for map-making and land surveying. GPS also provides an extremely precise time reference, required for telecommunications and some scientific research, including the study of…
What affects GPS accuracy?
Many factors affect how accurate your GPS is. The atmosphere, the ionosphere and the position of your receiver could all affect GPS accuracy. Any buildings, natural structures or heavy foliage that obstructs the GPS' view of the sky may decrease the position accuracy.
Does my T23 need a SIM card?
Yes, think of your T23 as another phone. You insert a SIM card and that phone number is where you send your text messages to.
What if I am outside GSM coverage area?
Your T23 will store up to 20 outgoing messages until it is connected to the GSM network. Incoming messages to your T23 are stored in the GSM network.
What if I go inside a building and lose GPS signal?
Your T23 stores your location when you enter the building and once outside and moving it will start updating your location again. The same applies to tunnels.
Why is my T23 not responding?
Check if the unit has power and not sleeping. You may see this with its green LED blinking. If this is your first use or the unit has been stored, charge the battery for 3.5 hours. If your T23 is installed then verify that GSM is working by calling the unit to see if you hear a ring tone. If no ring tone:There may be no GSM coverage, so move the unit to a suitable location.Verify that the PIN code was removed from the SIM.Remove the PIN code from the SIM.Verify you have the correct phone number.Verify that the SIM…
How does T23's security system work?
There are 3 user levels in the system: Owner - Can issue configuration commands and all below. Friend - Can use the reporting of the system and Guest commands. Guest - Can issue Find, Help and Status commands. Unregistered users and users without high enough security will not receive any response from the T23. This prevents unauthorized access of your location. The owner sets a password that can be used to re-register if your phone is lost.
What if I lose my phone?
You can re-register yourself as an owner by sending OWNER,password to your T23.
What if I move to another country?
You can update the landmarks in your T23 for over 220 countries.
I am unable to get my first location for more than 5 minutes, what could be the problem?
There should be no nearby tall buildings or houses. Antenna signal will not pass through metallic or magic type tint. Vehicle should not be moving when trying to get your first fix. Units should not be placed or covered behind metal objects. Acquiring your first location should take only 1 to 5 minutes with a good GPS signal in the area. Should the acquiring of a signal take too long, simply remove the unit's battery and re-insert it again - this re-starts the search process.
How long does it take for the unit to get its position?
With ideal conditions 1 to 5 minutes the first time you use the unit. The unit can re-establish its location in a few seconds.
How many landmarks can the system hold?
T23 can hold over 15,000 landmarks. Users can add hundreds of their own landmarks.
Why is my T23 not charging?
Check that the battery is installed. If first use or after a long period of storage, charge the battery for 3.5 hours. The power light will come on in 5-10 minutes. Replace the battery. Like mobile phones a T23 battery will wear out after a few years.
How long does the battery last?
One day with constant usage and weeks with limited activity. This is determined by how much time the unit is sleeping.
How do I take out the battery from the T23?
Press and slide the battery cover. Gently push the notch lock of the battery. Lift the battery out.
