3.4 Shutting down
To switch the receiver or the transmitter off, press and
hold the key for two seconds.
NOTE: The receiver 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 receiver. 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 receiver’s
headphone socket, which is located next to the
accessory panel.

3.6 Frequencies
The RD7000 supports a very large range of locatable,
active and passive frequencies. For a complete list
of supported frequencies, please refer to the table in
Appendix 9.6.
3.6.1 Passive frequencies
Passive frequency detection takes advantage of signals
that are already present on buried metallic conductors.
The RD7000 supports three types of passive frequencies:
Power, Radio and CPS (DL only) signals. You can detect
these 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 receiver. 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!
