lIf the target prism is lost during auto tracking status, the instrument will automatically change to Waiting status and symbol mark will be switched. If the target is found during Waiting status, tracking resumes, and if not, status changes to Searching status. When the target prism is found, tracking will resume.

Searching status

lAuto tracking status sometimes can be unstable for a few seconds after the optical path is disturbed. l If the center of reticle and the center of the prism is not coincided, you should adjust optical axis for

auto-tracking, refer to chapter 9"Check and adjustment".

l In the not suitable operating condition in such the atmospheric condition is not good by the heat shimmer, or other bad weather condition, in the long distance of the auto-tracking limit, can be happened not certain tracking or not tracking at the center of the prism.
