Safe Mode is designed to help you prevent from getting the LinkedIn Weekly Invite Limits.
Once you enable the safe mode, it will automatically increase the delay between invites and randomize them. It will also limit the total number of invites not to exceed 20 per day. Therefore, the Safe Mode will prevent your account from sending a large number of invitations in a short period, which Linkedin states as the primary reason for imposing weekly limits.
You can find the safe mode button in the “Account Settings” tab once you click on the “Settings” menu.
