16. Reading 3M
 iD Markers
The operator can retrieve the data from the iD marker by pressing Read [SK] on the 
Marker Locate display.
The receiver tip should be lowered to the ground to reach maximum read depth.
If more than one 3M
 iD Marker of the same utility is detected, the receiver will read 
the first marker and display the data from the marker.
The fourth yellow command key will be labeled 
Read Next”. Press this key to extract the data from 
the other marker.
All the information retrieved from the marker, including the date and time read, is 
saved into the ‘Read History’ file of the receiver. If a hand-held GPS device is used in 
conjunction with the receiver, coordinates will be saved into the "Read History" file also.
