2.2 Changing Menu Variables Using the
Keypad
Upon entering a menu, a pointer controlled by the Up/down arrows
keys points to the selected variable. Some are simple YES/NO or ON/
OFF entries toggled by pressing the Edit key. Others, such as Channel
ID and Eunits fields may have many ASCII character possibilities.
Allowed ASCII characters are as follows:
ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstu
vwxyz blank space”#$%&`()*+,-./0123456789:;<=>?@.
Notice the often used blank character is located after lower case z and
before the exclamation point !. Edit places a cursor under the item
and Up/down arrows scroll through each allowed entry. The Next key
moves the cursor to the next position within a field. When the field is
complete, Edit clears the cursor and loads the field into non-volatile
memory where it is retained indefinitely. Without a cursor present, the
Next key closes open menus in reverse order and returns the LCD to
the data display.
2.2.1 Setup Conguration Menus
The SETUP menu (shown in the middle of Figure 2-16 and in Figure
2-17) is accessed by pressing Edit when any data display is present.
This is the entry-level screen to all Channel, System and Security
menus. It also shows the firmware version operating in the HA40.
Use the up/down arrow keys to move the pointer to the desired menu
and press the Edit key.
