ALWAYS EXCAVATE WITH CARE
C.Scope Locators detect services radiating a detectable signal. There may be some services that do not radiate a signal and cannot be located.
Do not use the equipment outside of the temperature range -10˚C to +50˚C (14˚F to 122˚F) as the batteries may cease to function adequately.
Geographical conditions such as hills and mountains may effectively screen signals and prevent a detectable Radio signal.
The Locators alone will not always locate every service. Use a Signal Generator/Transmitter wherever possible.
Do not touch the metal of the Signal Generator/ Transmitter Crocodile Clips or of the Plastic Pipe Tracer or Flexible Tracer terminals when in use.
The Signal Generator/ Transmitter leads MUST NOT be connected directly to a live service.
Beware of multiple services. The Locators will not always indicate services that are close together or one above the other.
Do not use the equipment in areas where hazardous gases may be present.
Check for underground services before using the Earth Stake.
Always make sure that the Locator and Signal Generator/Transmitter are set to the same frequency when used together.
Performance may be impaired by unusually strong electromagnetic fields.
Do not hold the Locator Loudspeaker close to the ear for extended periods.
It is recommended that the operation of the Locator and Signal Generator/ Transmitter is regularly checked (see pages 53-56).

SGA4 and SGV4 Signal Generator
4
SGA4 Signal Generator
The SGA4 Signal Generator is designed for use
with the CXL4 and DXL4 Locators.
• High (One Watt) and low Power Output settings.
• Pulsed or Continuous output signal.
• Loud or Muted audible output.
SGV4 Signal Generator
The SGV4 Signal Generator is designed for use
with the CXL4 and DXL4 Locators.
• Automatic Daily Self Test.
• Data Logging of all Signal Generator activity.
• Automatic Back-light.
• Four Power Output settings up to One Watt.
• Pulsed or Continuous output signal.
• Loud, Muted or Silent audible output settings.
• Combined Frequency (CF) signal output (33kHz and 131kHz)
applicable using both Connected and Induced methods
of signal transfer.
MXT4 Transmitter
5
MXT4 Transmitter
The MXT4 Transmitter is designed for use with the MXL4 Locator.
• Automatic Daily Self Test.
• Data Logging of all Transmitter activity.
• Automatic Back-light.
• Four Power Output settings up to One Watt.
• Pulsed or Continuous output signal.
• Loud, Muted or Silent audible output settings.
• Six Frequency settings: 512Hz, 640Hz, 8kHz, 33kHz,
CF (33kHz and 131kHz combined), 131kHz (HF).
• All Frequencies applicable using the Direct Connect method
of signal transfer.
• 8kHz, 33kHz, CF (33kHz and 131kHz combined), 131kHz (HF)
frequencies applicable using the Induced method of signal transfer.
In Power Mode the Locator detects power signals. These power signals are present on all current carrying electricity cables
although not all are detectable. Power signals may also flow along other conductors such as metal gas and water pipes,
telecom cables, metal fences and railway tracks.
Limitations of Power Mode
Not all electricity cables can be found using the Power Mode. Here are the most important examples of electricity cables
that may not be detectable in the Power Mode:
l Street lighting cables. When the lights are off, no current flows and so no power signal is created.
l Supplies to buildings or plant using very little or no electricity may not have a detectable power signal.
l Pot-ended or capped cables. These will never have any current flowing through them but are possibly still live.
l Disused or abandoned cables.
l A few high voltage electricity cables. These can be ‘well balanced’, electrically and therefore radiate little or no power signal.
l Direct Current cables (such as those found on railway systems). These do not create their own Power signals.
l Cables more than 3m (9’9”) deep.
Locator Operating Modes: Power Mode
NOTE Locators can only detect services radiating a detectable electromagnetic signal.
There may be some services that do not radiate these signals and cannot be located.
NOTE The absence of a power signal does not mean the service is not live.
WARNING Generally these services should be detectable using the Radio or Generator/Transmitter Modes.
6
In Radio Mode, the Locator detects signals from various radio transmitters. These signals flow through the ground
and will tend to follow the line of least resistance such as a buried metallic service. When this happens the service
can often be detected by using the Locator in Radio Mode.
Limitations of Radio Mode
l Not all services will be detectable in Radio Mode.
l A strong radio signal present on one service may be masking a weaker radio signal present on an adjacent service.
l It is not normally possible to determine what the service is in Radio Mode, only it’s position.
l Radio signals do not favour one utility over another.
l The depth of the buried service cannot be judged by the strength of the radio signal alone.
l Normally it is only possible to detect radio signals present on services up to 2 m (6’6”) deep.
l A short service may not have enough signal to be detected.
Locator Operating Modes: Radio Mode
NOTE Locators can only detect services radiating a detectable electromagnetic signal.
There may be some services that do not radiate these signals and cannot be located.
7
WARNING Most buried metallic services not found in Radio Mode should be detectable by using Generator Mode
with the Signal Generator/ Transmitter.
In All Scan Mode, the Locator detects at ALL frequencies in a wide band. Sometimes a signal that is outside of the frequency
range of the other search modes (Power, Radio, and Generator/ Transmitter)will be present on a buried metallic service.
All Scan Mode is a useful additional search mode to employ as it may detect these ‘extra’ signals as well as the Power, Radio
and Generator/ Transmitter signals.
Using the All Scan Mode is also a good way to confirm the accuracy of the marking of metal pipes and cables previously detected
using the Power, Radio and Generator/ Transmitter modes of detection.
