1.3 Good Habits for Managing the WAH7003
Do the following things regularly to make the WAH7003 more secure and to manage it more
effectively.
• Change the password often. 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 WAH7003 to its factory default settings. If you
backed up an earlier configuration file, you won’t have to totally re-configure the WAH7003; you
can simply restore your last configuration.
1.4 Hardware Connections
See your Quick Start Guide for information on making hardware connections. You need to insert a
SIM card before you can use the WAH7003.
1.5 Turn on/off the WAH7003
To turn on the device, press the power button and hold until the ZyXEL logo displays in the OLED
screen.
To turn off the device, press the power button and hold until the word “BYE” displays in the OLED
screen.

display in the OLED screen to see the connection status, battery life and signal strength.
