C.1 ENABLING OF SETUP FROM KEYBOARD
Setting up using the keyboard, a function which is disabled by default, can be enabled by operating
directly on the printed circuit and shortcircuiting the jumper JP1 by soldering (see diagram below).
Take care not to shortcircuit the JP3 jumper next to it, which is pre-set for internal use (control test
during operations).
