1.3 Good Habits for Managing the ES-305
Do the following things regularly to make the ES-305 more secure and to manage the ES-305
more effectively.
• Change the username and password. Use a password that’s not easy to guess and that
consists of different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an
earlier working configuration may be useful if the device becomes unstable or even
crashes. If you forget your password, you will have to reset the ES-305 to its factory
default settings. If you backed up an earlier configuration file, you would not have to
totally re-configure the ES-305. You could simply restore your last configuration.
