within is accurate at time of publication; however the
RD7000, this manual and all its contents are subject to
change.
Radiodetection Limited reserves the right to modify the
product without notice and some product changes may
have taken place after this user manual was published.
Contact your local Radiodetection dealer or visit

the RD7000 product family, including this manual.
Important notices
General
The performance of any cable and pipe locator may be
affected when used in close proximity to ferrous materials
such as manhole covers, steel-toe boots and nearby
vehicles. Keep a distance of one or two meters from
these objects when taking critical measurements such as
depth and current readings.
This instrument, or family of instruments, will not be
permanently damaged by reasonable electrostatic
discharge and has been tested in accordance with IEC
801-2. However, in extreme cases temporary malfunction
may occur. If this happens, switch off, wait and switch on
again. If the instrument still malfunctions, disconnect the
batteries for a few seconds.
Safety
This equipment should be used by fully qualied and
trained personnel only.
Radiodetection receivers detect almost all buried cables
and most conductors, but there are some which do not
radiate signals and which Radiodetection receivers cannot
detect. Radiodetection receivers do not indicate whether
a signal is from a single cable, several buried side by side
or one above another. Exercise caution and due diligence
when conducting any survey.
Making a direct connection to live power lines is extremely
dangerous to life. Do not attempt any direct connection
unless you are fully trained and qualied to do so.
WARNING! The transmitter is capable of
outputting potentially lethal voltages. Take care when
applying signals to any pipe or cable and be sure to
notify other technicians who may be working on the
line.
Reduce audio level before using headphones to avoid
damaging your hearing.
WARNING! This equipment is NOT approved for
use in areas where hazardous gases may be present.
WARNING! When using the transmitter, switch off
the unit and disconnect cables before removing the
battery pack.
WARNING! The RD7000 will detect almost all
buried conductors but there are some objects that
do not radiate any detectable signal. The RD7000,
or any other electromagnetic locator, cannot detect
these objects so proceed with caution. There are also
some live cables which the RD7000 will not be able to
detect in Power mode. The RD7000 does not indicate
whether a signal is from a single cable or from several
in close proximity.
Batteries
WARNING! Alkaline batteries can get hot after
prolonged use at full output power. Take care while
replacing or handling the batteries.
Battery disposal
Ni-Cad batteries should be disposed of in accordance
with your company’s work practice, and/or the relevant
laws or guidelines in your country or municipality.

RD7000 Operation Manual 5
Section 3. – Basic Operation
3.1 Starting the system
The receiver and transmitter are battery powered.
Install good quality D-cell NiMH or Alkaline batteries
into the receiver and transmitter battery compartments.
Alternatively, you can power the transmitter from a mains
or vehicle power source using a Radiodetection supplied
adapter.
To switch the receiver or the transmitter on, press and
hold the keypad Power Key for two seconds. When you
switch the system on it will perform an LCD segment
check. It will then display the model number followed
by the rmware version. This information is important if
you need to contact Radiodetection technical support or
update your receiver to the latest rmware.
NOTE: Once the system is switched on, pressing the
Power Key momentarily will activate the receiver or
transmitter menu.
3.1.1 Batteries
The LCD provides a battery level indicator (refer to
the diagrams in Sections 2.1 and 2.2). When battery
replacement is necessary, the LCD shows a ashing
battery icon. The expected battery life under normal
working conditions is approximately 30 hours on the
receiver and 15 hours on the transmitter.
NOTE: Prolonged use of high power output on the
transmitter will reduce battery life.
To replace the batteries on the receiver, unlatch the
battery compartment cover, which is located above
the accessory panel, and lower the tray. Remove the
spent batteries and insert two D-Cell Alkaline or Ni-Cad
batteries.
To replace the batteries on the transmitter, unlatch the
accessory tray. The battery compartment is located
underneath the transmitter body. Use the turnkey to
unlatch the battery compartment. Remove the spent
batteries and insert eight D-Cell Alkaline or Ni-Cad
batteries.
NOTE: When installing batteries always observe the
correct battery polarity as indicated on the battery tray.
Rechargeable battery pack
An optional Lithium Ion rechargeable battery pack is
available for the RD7000 Tx1, Tx3 and Tx10 transmitters.
The rechargeable battery pack offers an 8-hour lifespan,
depending on use.
The pack is available in a kit that includes the
rechargeable battery pack, AC adapter and a vehicle
adapter.
The battery pack must be removed from the transmitter
before it is connected to a power source for recharging.
For more information, refer to the instructions that came
with your charger.
WARNING! Do not heat the rechargeable battery pack
above 60°C (140°F) as this will damage the battery’s
thermal fuses.
NOTE: The battery is designed to protect itself against
over discharge, overcharge and short circuit between
charge terminals.
Contact your local Radiodetection representative for
information on purchasing battery packs and chargers.
3.2 System setup
It is important that you set up the system according to
your personal preferences and operating requirements
before you conduct your rst survey. You can set the
