6.4.3 Password Protection

If a password has not been programmed into the unit, the PASSWORD screen can be bypassed simply by pressing

"E". To enter a password, scroll down to the PASSWORD screen in the CHANGE SETTINGS Submenu, press "E",

using the UP and DOWN keys, scroll up or down to the desired letter or number, press the RIGHT arrow key to

move to the next space and select the desired letter or number, repeat for the remaining two spaces and then press

"E". You will be asked to verify the password change. Retype the password to verify and press "E".

It will be necessary to enter this password to gain access to the CHANGE SETTINGS submenu from this point.

To change the password just repeat the above instructions. To erase the password, thereby defaulting back to the

original unit setting, program blank spaces in the CHANGE PASSWORD screen.

If a password is lost or unknown, call your local service center for further instructions.
