Changing Menu Variables using the Keypad
Upon entering a menu, a pointer controlled by the UP/DOWN keys indicates 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[\]^_`abcdefghijklmnopqrstuvwxyz 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 scrolls 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.

revision of firmware operating in the TXP-C20. Use the UP/DOWN keys to move the pointer to the desired menu
and press the EDIT key.
