Q: I do not see my ZTrak unit(s) in Ground Traffic Control.
A: The device(s) may not be visible due to one of the following reasons:
- ZTrak units are visible in the ZTrak GPS Track and Trace report. Contact Zonar if you do not see ZTrak as a selectable option in Reports > GPS Track & Trace > ZTrak.
- ZTrak unit is set to inactive.
Solution: Go to Manage > Assets in Ground Traffic Control. Ensure you have “Active and Inactive” assets visible. Find/Edit your asset and ensure that it is set to “Active.” - The ZTrak unit is not properly configured.
Solution: Go to Manage > Assets in Ground Traffic Control. Ensure that the “GPS Device Type” is set to “ZTrak.”
Q: How does movement tracking work?
A: Movement tracking is triggered by the built-in accelerometer on the device. The device will record a location point every 3 minutes and upload a batch of 10 points every half hour. (if a trip is shorter than 30 mins, the device uploads after 5 mins of non-movement).
Q: How does Wi-Fi lookup and cellular triangulation fallback work?
A: By default, the device will concurrently look for both GNSS (GPS) and Wi-Fi signals during a location report, this ensure location resolution reliability when GPS signals are weak or non-existent (under trees, indoors, etc.). Wi-Fi resolution are based known Wi-Fi Access Points from Cloud geolocation database services, so the precision can be less accurate than GPS. In the case where both GPS and Wi-Fi location resolution fails, the device will fall back to cell tower triangulation (less precise than Wi-Fi).
Q: How do I request recovery mode for an asset tracker?
A: Contact Zonar Support to enable Theft Recovery Mode. Theft Recovery Mode will provide a near-real-time ping rate at once per minute. Due to the battery-powered nature of device, Theft Recovery Mode can be only enabled to a max of 2 hours.
Theft Recovery Mode will download and activated on the ZTrak when the device is in motion.
Q: Is the device battery field-replaceable?
A: While the ZTrak (AT22) device battery life is designed to last up to 10 years (on 2 pings/day) without having to change the battery, the battery is field-replaceable should there be a need. The devices uses 3x Energizer L92 that can be found off-the-shelf. The enclosure (6 screws) can be opened by the user to access the battery compartment. Ensure an even-tightening of the enclosure screws when closing the enclosure in order to preserve water-tightness.
Q: How long can the batteries in the ZTrak (AT22) last?
A: The life of the batteries are determined based on the number of daily updates scheduled. Refer to the Battery Matrix below for our estimates based on scheduled reporting rates:
| # Daily Updates | Battery Life |
| 1 | 10 years |
| 2 | 10 years |
| 4 | 8 years |
| Movement based Tracking |
Depends on asset movement pattern *Current estimate 1.5 - 2 years of battery life for an asset that moves an average of 3 hours per day |
Q: What do I do if my ZTrak (AT22) has not reported a location recently?
A: There are a few possible causes for a ZTrak (AT22) unit to have a delay in location reporting:
- Unit is sleeping (non-issue)
Solution: Wait for a call home from the unit. The unit is designed to call home and report its location at a regular rate based on the frequency chosen when the unit was purchased. - There is poor cellular coverage due to geographic location, cellular network type, or installation location.
Solution: Ensure that the unit is installed in an area with cellular coverage and is mounted high in the vehicle, free from metallic obstructions. - The temperature is too hot or cold for the ZTrak (AT22) unit to operate.
Solution: Move the ZTrak (AT22) unit to an appropriate location with a temperature range of -30C to 60C (-22F to 140F). - The SIM (Cellular chip) is not activated or (if it is outside of the United States) is not set to roaming.
Solution: Contact Zonar to check the SIM status (877-843-3847).
Q: How do I adjust my ZTrak ping rate?
A: Contact your sales representative for options and pricing on increased ping rates. There is a nominal fee increase due to the extended bandwidth required for increased rates. Additionally, be aware that in optimal conditions the battery life of 10 years is based on two pings per day; environmental temperatures and increased ping rates may shorten the battery life.
