five years. The timing of battery replacement
varies depending on the frequency of use and the
environment of where the instrument is stored
while not in use.

13.2 Atmospheric Correction

The speed at which light travels through the air varies depending on the temperature and
atmospheric pressure. The R-200 series is designed to measure distances at the speed of light
in order to measure accurately, Atmospheric Correction needs to be used. The instrument is

13. APPENDIX

What to do
Re-level the instrument. Repair is
needed if the message is displayed
when it is properly leveled.
Press the [ESC] key and enter the
correct data.
Select the correct target mode.
Select a longer point, or use a tape
measure.
Change the object that has much
better reflectivity, or use a reflecting
sheet, or wait until the sun activity
has weakened.
Turn the power off, and then turn on
again.
Repair is needed when the
message appears consistently.
Have the lithium battery replaced by the
dealer from whom the instrument was
purchased.
