c. Start auto-speed function after NVF-200R reboots.
d. NVF-800S will try to link at 25M mode with NVF-200R. If it fails, auto-speed goes down to 15M mode and re-link
with NVF-200R. If it fails again, auto-speed goes down to 5M and keeps this mode then re-link with NVF-200R.
e. Please note any length of phone cable change, NVF-200R must re-powered again due to auto-speed function work
only when restarting.
