Option Switch Settings
The processor board is equipped with a dip
switch. Each switch position and combina-
tion of positions can be used to configure dif-
ferent programming options, such as the pro-
graming option listed above for Flash update
mode.
If your settings should accidentally get
changed, or your replacement processor board
is shipped from the factory with the incorrect
settings for your product, the following tables
detail the appropriate switch positions for
restoring your instrument to proper operation.
