Globallink 520 reboots

Hey,

I have random reboots of my Globallink 520. It I difficult to use the relais if it always change the status for the reboot.

I do not see a clear reason for reboot. Sometime every 30 min, sometimes different. Is it maybe because of short signal drops? I have an external antenna and most of the time perfect signal. Sometimes single drops of signal quality. Is it then a reboot for a new sim card login and hope for better signal? I would like to deactivate such a setting. Better longer bad/no signal as a reboot with change of my relais status.

Thanks a lot,

Peter
