Operator's Manual for 3M Dynatel 1420-iD Marker Locator

Quick Guide

The 3M Dynatel 1420-iD and 1420E-iD are electronic marker locators designed to locate, read, and write information to 3M iD Markers. For E-Model (Export) units, an initial configuration via PC Tools software is required before use. Ensure the unit is configured for the specific country of operation to comply with local regulations.

Safety Information

Always follow safety guidelines to prevent electric shock or injury. Do not operate the unit in countries with non-specific configuration settings. The device is designed for locating buried markers; use only as specified to maintain safety protections.

Battery Installation

The unit uses 8 'AA' (LR 6) Alkaline batteries. To install: twist the cap to open the battery compartment, slide the compartment out of the handle, and insert batteries observing correct polarity. Always remove batteries when storing the unit for long periods.

Keypad and Display

The interface includes a power button, volume control, gain adjustment, and soft keys (yellow) whose functions change based on the current mode. The display shows signal strength, battery level, and operational data. Use the Menu button to access configuration settings, including clock, language, and marker types.

Locating Markers

To locate markers, press the Locate/OK button. Enable desired marker types in the Setup menu. For single marker locate, select the utility type and adjust the Gain until the bar graph opens. When a marker is detected, the signal strength will be at its maximum. For dual marker locate, select two utility types and follow the same procedure.

iD Marker Operations

Creating Templates: Use the User Template screen to create or edit templates for writing to iD markers. It is recommended to create templates using the 3M Dynatel PC Tool Kit software and download them to the locator.

Writing to Markers: Select a template, configure write options (Overwrite, X-Type, Marker type, Lock/Unlock), and hold the locator over the marker. Ensure the locator is within the maximum writing range (e.g., 6 inches for Near-Surface, 12 inches for Ball, 24 inches for Full-Range).

Reading Markers: Lower the locator tip to the ground over the marker and press Read. The locator will display the marker's data, which is automatically saved to the Read History.

GPS Compatibility

The locator can communicate with GPS devices via the Serial Port. Configure the COM Setup to NMEA (to receive coordinates) or GIS (to send/receive data). When connected, marker data can be stamped with latitude, longitude, and date/time information for mapping purposes.

Maintenance and Self Test

Clean the unit with a damp cloth. Use the Self Test mode in the menu to verify unit information, including serial number, software revision, and hardware revision.
