Fig. 3-3 Battery low warning
• The battery low warning "BATTERY?" is temporarily
cleared when you press a function key. It will however
reappear after about a minute because the battery
voltage is measured at one-minute intervals.
• The warning will also be displayed when the instrument is
powered by the AC adapter and there are no batteries in
the set.
