supply. To change power frequency on the locator:
1. Press the key momentarily to enter the menu.
2. Press the or keys until POWER is displayed.
. Press the locator key to enter the POWER submenu.
. Use the or keys to select the correct frequency.
. Press the key to accept your selection.
Language
To select your preferred menu language:
1. Press the key momentarily to enter the menu.
2. Press the or keys until LANG is displayed.
. Press the locator key or transmitter
. Press the or arrows to select your preferred language.
. Press the key to accept your selection and return to the main menu.
. Press the key momentarily to return to the main operation screen.
Depth Measurement Units (locator only)
The RD7000+ allows you to work in Metric or Imperial units. To select your preferred
units of measurement:
1. Press the key momentarily to enter the menu.
2. Press the or keys until UNIT is displayed.
. Press the key to enter the UNIT submenu.
. Press the or arrows to select Metric or Imperial units.

. Press the key momentarily to return to the main operation screen.
Battery
The RD7000+ locator and transmitter support Alkaline, NiMH or Lithium Ion batteries.
It is important that you set the system to match the currently installed battery type to
ensure optimal performance and correct battery level indication. To set your battery type:
1. Press the key momentarily to enter the menu.
2. Press the or keys until BATT is displayed.
. Press the locator key or transmitter
key to enter the LANG submenu.
key to enter the BATT submenu.

Locating pipes and cables
passive Frequencies
Passive frequency detection takes advantage of signals that may already be present on
buried metallic conductors. The RD7000+ supports three types of passive frequencies:
Power, Radio and CPS (Cathodic Protection Signal). You may detect these frequencies
without the aid of the transmitter.
Active Frequencies
Active frequencies are applied directly to the pipe or cable using the transmitter and
are the preferred method of applying a signal to a conductor using the transmitter. The
transmitter can apply a signal using two methods: induction and direct connection.
Induction
The transmitter is placed on the ground over or near the survey area. You select the
appropriate frequency. The transmitter will then induce the signal to any nearby metallic
conductors. In induction mode, using higher frequencies is generally recommended as
they are induced more easily onto conductors.
Direct connection
In direct connection, you connect the transmitter output directly to the pipe or to the
conductor of the cable you wish to survey. The transmitter will then apply an active
frequency signal to the line, which you can locate using the locator. This method
provides the best signal on an individual line and enables the use of lower frequencies,
which can be traced for longer distances.
Connecting the transmitter to a pipe or line requires the use of a direct connection lead
connected to the accessory socket of the transmitter. The red lead is connected to the
pipe or cable and the black lead connected to an earth stake to complete the electrical
circuit.
WARNING! Direct connection to live wires is POTENTIALLY LETHAL.
Direct connections should be attempted by fully qualified personnel only!
WARNING! The transmitter is capable of outputting potentially lethal
voltages. Take care when handling the terminals, connection leads and
ground stake, notify other technicians working on the line of the hazard
and guard exposed conductors to prevent accidental contact.
