12.1 Returned Signal Checking
• Check to make sure that sufficient reflected light is returned by the reflective
prism sighted by the telescope. Checking the returned signal is particularly
useful when performing long distance measurements.
• When the light intensity is sufficient even though the center of the reflective
prism and the reticle are slightly misaligned (short distance etc.), "*" will be
displayed in some cases, but in fact, accurate measurement is impossible.
Therefore make sure that the target center is sighted correctly.
