using a 100% weight that is at least 200g larger than the 0% weight. During training,
the ZERO key may be used to assist in setting the 0% and 100% values. This will

relative, weights.

Battery Level Indicator
The battery level indicator shows the relative strength of the batteries. Full power is
indicated by four bars. As the batteries are depleted, the number of bars displayed
decreases, until no bars are left. At this point, it is necessary to replace the batteries (refer
to the Battery Installation section above). If the battery power drops to the point where the
DRS220 can no longer function accurately, the alarm will beep 20 times and the power will
turn off automatically. When the batteries are replaced, and the scale is turned back on, the
DRS220 will resume operation with all previous setting intact.
