Question
Can the LN-150 be operated with TopLayout “Ver2.0”?
Answer
WLAN connection is possible, but it is connected as LN-100. Since the measurement range of LN-100 is 100m, measurements over 100m are not possible. BT connection cannot be selected because LN-150 does not appear as a selectable option.

Question
Is there any difference when operating LN-150 and LN-100 with TopLayout “Ver2.1”?
Answer
Both Bluetooth and WLAN connections work without issue. When connected to the LN-100, measurements can be taken up to approximately 100 meters under good communication conditions. When connected to the LN-150, measurements can be taken up to approximately 130 meters under good communication conditions.

Question
Where do I enter the height of instrument?

Question
When setting the height for instrument placement during resection, can the BM be specified?
