Introduction Congratulations on the purchase of your new 8890/8891 Locator. The 889X Series
Locator is specially designed to detect passive electronic markers.
The ReceiveR detects the signal. You can locate the relative posi-
tion of the buried marker by locating the point of the highest signal.
Prepare for Use
Unpack your new 8890/8891 Locator . Make sure there is no shipping damage
and all the parts are included.
Locate the battery compartment on the back of the “head” of the ReceiveR.
Open the compartment using a phillips screwdriver. Install the six Duracell® “C”
batteries as marked.
Note: For longer battery life and reliable operation under adverse conditions,
use only Duracell® alkaline batteries.
Electric shock hazard:
• Tool is designed to detect electromagnetic eld emitted from buried metallic
utilities. There are buried cables, pipes, and utilities this instrument CANNOT
detect.
• LOCATING is not an exact science. The only certain way to be sure of the ex-
istence, location, or depth of buried utilities is to carefully expose (dig up) the
utility.
• De-energize any circuits in or around the work area.
• Do not expose tool to rain or moisture.
• Use tool only for intended purpose as described in this manual
Failure to observe these warnings could result in severe injury or death.

Locating
Locating A Passive Electronic Marker
It i s ideal t o have a general i dea o f where a marker may be buried. By first
locating the utility, the user has a path in witch the marker is buried.
Select desired gain setting. M ost markers may be located on lowest gain set-
ting. Use high gain if marker is known to be deep.
Move the RECEIVER at a medium speed side to side while walking a straight line.
Move slowly so a marker may not be missed. The RECEIVER will detect a marker
just a few feet away so a grid search may be needed to find a marker.
The RECEIVER will g ive a maximum signal when d irectly over t he m arker. GAIN
adjustment may be needed for optimum sensitivity.
NOTE: IT IS POSSIBLE TO DETECT AN ON-TARGET MARKER.
