ABOUT THE USE
Basically the LH 965 menu system is built up as a book which you can flip
through. The functions of the computer are divided into a main menu and the
following 4 sets of functions:
OPERATION
ENCODE
DATA/DELETE
TEST
Each of the above function sets have several sub functions. Each function set with
sub functions will be described one by one on the following pages.
ABOUT THE OPERATION
FUNCTION KEYS (SOFTKEYS)
Operation of the LH 965 is very simple with the 4 function keys (softkeys) to the
right of the display - the four keys are each marked with a white vertical dash. The
present function of these keys is displayed to the left of the key. When a key is
pressed the 4 function keys can change into a new function (see ill.).
RETURN KEY
This key is used if you want to return to a previous
menu/function. One “page” (picture) is changed each
time the key is pressed. The key is also used to
accept a RPM warning if it does not require a stop.
