The battery power indicator shows the level of battery strength.
2.4 Vertical Angle Tilt Correction
(DT-205/205L only)
When the tilt sensor is activated, automatic correction of vertical angle for
mislevelment is displayed. To ensure a precise angle measurement, tilt sen-
sors must be turned on. If the "b" display appears the instrument is out of
automatic compensation range and must be leveled manually.
In case the instrument is used in an unstable situation, constant indexing of
vertical angle may be impossible. In this case, the function of tilt correction
can be stopped.
To stop the function of tilt correction, refer to Chapter 6 “SELECTING
MODE”.

(DT-205/205L only)
Serial signal connector is used for connecting the DT-205/205L with a com-
puter, which enables the computer to receive measurement data from the
DT-205/205L.
