Here are Miyagi's scripts (with his permission) to reset the options;
After telent, and login. Input these commands:
mount -o remount,rw,sync /usr/bin/siglent/firmdata0
rm /usr/bin/siglent/usr/usr/options_mso_times.txt
rm /usr/bin/siglent/usr/usr/options_awg_times.txt
rm /usr/bin/siglent/usr/usr/options_flx_times.txt
rm /usr/bin/siglent/usr/usr/options_canfd_times.txt
rm /usr/bin/siglent/usr/usr/options_i2s_times.txt
rm /usr/bin/siglent/usr/usr/options_1553b_times.txt
rm /usr/bin/siglent/usr/usr/options_pa_times.txt
I have not tried this (yet) but I assume they will work fine. At least with this firmware.
