9. Battery RAM
All operating parameters selected from the configuration menus are saved in battery backed-up RAM
(Random Access Memory). Therefore, if AC power to the A/S-4 is interrupted, it is unnecessary to
reenter the parameters previously selected. If the unit is powered off for seven days or more, the
parameters will probably be lost.
