3.4 Shutting down
To switch the locator or the transmitter off, press and hold
the
key for two seconds.
NOTE: The locator will automatically power off if no
keys are pressed after a five minute duration.
3.5 Headphones
Radiodetection supplies an optional headphone set
for the RD7000+ locator. The headphones feature an
adjustable headband to ensure a tight fit when used in
the field. The accessory headphones also feature volume
adjustment for both left and right speakers.
Connect the 3.5mm headphone jack into the locator's
headphone socket, which is located next to the
accessory panel on the front of the locator.
NOTE: Before wearing headphones, lower the locator's
volume levels to help prevent damage to your hearing.

WARNING! Wearing headphones may impede
your awareness to dangers in the field such as
moving traffic or other heavy machinery. Exercise
caution!
3.6 Frequencies
The RD7000+ supports a large range of locatable active
and passive frequencies. For a complete list of supported
frequencies, please refer to the table in Appendix 10.2.
3.6.1 Passive frequencies
Passive frequency detection takes advantage of signals
that are already present on buried metallic conductors. The
RD7000+ range supports up to three types of passive
frequencies: Power, Radio and Cathodic Protection System
(CPS, RD7000DL+ only) signals. You can detect these
connections
®
frequencies without the aid of a transmitter if they are
present on the utility you are surveying.
3.6.2 Active frequencies
Active frequencies are applied direct to a buried 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 indiscriminately to
any nearby metallic conductor. In induction mode, using
higher frequencies is generally recommended as they are
induced easier onto nearby conductors.
Direct connection
In direct connection, you connect the transmitter directly
to the pipe or cable you wish to survey. The transmitter
will then apply a discreet 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 or clamp and a ground
stake to complete the circuit. For more information about
signal clamps and other direct connection accessories,
please refer to Section 7.
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
