Please note the location of the Power Button, LED Lights, and micro USB Shipping Mode After initial programming, the device will enter a low power shipping mode. In this mode the device will perform no operation other than monitor the pushbutton. To exit shipping mode the user must press and hold the pushbutton for at least 5 seconds. After a successful exit from shipping mode the device will only re‐enter shipping mode if re‐programmed or user pushbutton sequence to re‐enter is performed. LED behavior The device has a visible multi‐colored LED used to provide user feedback about device mode and status. LL‐AF2‐ST‐SM‐RTK02 SuperTag Rechargeable 4 Shipping mode: Button hold Red LED blink Red LED solid Green LED solid White LED blink End state Button < 1 sec ‐‐ 3 sec 1 sec (if FW lock enabled) ‐‐ Shipping mode Button >= 1 sec and Button < 3 sec 1x per sec 3 sec 1 sec (if FW lock enabled) ‐‐ Shipping mode Button > 3 sec 1x per sec ‐‐ ‐‐ 5x rapid Normal operation Startup from shipping mode: blink blue LED 3 times (exit shipping mode), blink white LED 5 times (application start). Startup/reset normal: blink blue LED 3 times (bootloader), blink white LED 5 times (application start). Operation mode: 1 White blink fast during location scan Cloud sync: see cloud sync behavior Device cannot connect/constantly resetting: the blue LED will blink 3 times, then there will be a pause, and the blue LED will blink 3 more times. This behavior will continue indefinitely, without the device’s white LED blinking. This means that the device has an error. Possible cause is low battery; battery cannot handle the pulse current for LTE‐M. Cloud sync The cloud sync feature allows the user to force the device to send an uplink and check for any pending mailbox messages. When the cloud sync pushbutton sequence is performed the device will immediately send a diagnostic event count message and check downlink mailbox using the current modes network (SymBLE or LTE‐m). If a location update is in progress this will also be sent with the uplink; however, if a GPS is in progress the scan will be stopped due to potential long GPS scan times and the next location type will be started. The LED is used to indicate to the user the result of the mailbox check: 1 ‐ Green LED blink (5s): downlink mailbox check success with mail 2 ‐ White LED blink (5s): downlink mailbox check success no mail 3 ‐ Red LED blink (5s): downlink mailbox check failed LL‐AF2‐ST‐SM‐RTK02 SuperTag Rechargeable 5 Frequently Asked Questions (FAQ) Question Answer How do I power on the device? Device is powered on by pressing/holding the button for 5 seconds. The LED will blink blue 3 times and white 5 times to indicate it is powered up. If no LED response, then ensure the device is fully charged by connecting the USB to an appropriate power source. How do I diagnose what is going on with my device? Most of the device diagnostics can be observed from the LED light on the device. Can I power down the device? Devices do not have the ability to be powered off after the initial power on unless the batteries are removed. Can I change the configuration of the device? Device configurations can be changed by setting up an AirFinder account at apps.airfinder.com, or submitting a support ticket to https://link‐labs.zendesk.com/hc/en‐ us/requests/new?ticket_form_id=360000334931 LL‐AF2‐ST‐SM‐RTK02 SuperTag Rechargeable 6 FCC warming message: This device complies with Part 15 of the FCC Rules.
