4.2.5. Reset button
Fig. 4.6: Reset button
The Reset button is placed close to the SIM holders and it is labeled
"Reset". Use a blunt tool with 1 mm in diameter (e.g. paper clip) to press
the button.
Keep it pressed for at least 3 seconds for reboot and at least 10 seconds
for a factory reset. The start of the factory reset is confirmed by all LEDs
lighting up for one second. The button can be released afterwards.
Note
If the button is being pressed at least 15 seconds until all
LED diodes blink red, the recovery procedure is started. The recovery image can be provided
on demand and a special procedure utilizing the TFTP transfer from your computer is re-
quired. Contact our technical support team for more details.
