Keypad
The optiPoint 410/420 economy/economy plus/standard S V7.0 keypad
features digits, letters and some special characters. Depending on the se-
lected input mode, you can key in letters and special characters by press-
ing the relevant key as often as necessary until the required character ap-
pears on the display.
Examples of letter inputs are the password, the user name, or FTP down-
load files and file paths respectively.
For example, if you want to enter the letter "R", press "7" three times as "R"
is at the third position. For the letter "U", press "8" twice.
