I replaced by XL350TM with a new one. The new one had the old software version, but I now updated it to v9.150, so the 3 page 'options' reappeared (instead of just the 1 pager for the older version). However, for some reason the 'Enable Safety Alerts' icon is now grayed out and I can't use it: can you please tell me how I can get that back?
