EMC Declaration of Conformity

This receiver has been tested and found to comply with the limits for a

Class B digital device for radio noise for digital apparatus set out in the

Radio Interference Regulations of the Canadian Department of Com-

munication, and is pursuant to part 15 of the Federal Communication

Commission (FCC) rules. These limits are designed to provide reason-

able protection against harmful interference in a residential installation.

This receiver generates radio frequency. If it’s not used in accordance

with the instructions, it may cause harmful interference to radio or televi-

sion reception. Such interference can be determined by turning the re-

ceiver off and on. You are encouraged to try eliminating the interference

by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the laser and the receiver.

For more information, consult your dealer or an experience

Offset on-grade clamp position - clamp

position is sensed automatically and

displayed. Offset clamp position moves

the on-grade location to allow more grade

information to be displayed above grade.

This is useful in applications where going

below grade is not required, i.e. driving

stakes down to grade.
