Danger
The absence of a positive indication does not guarantee the non-existence of a service.
Services without a detectable signal may be present.
The Locators can only locate non-metallic services such as plastic pipes, typically used by the
water and gas utilities, with the use of appropriate accessories.
Precautions:
Always excavate with care.
Only with a Locator with depth:
The depth reading might not reflect the real depth if your Locator picks up the signal induced
into the service by the Transmitter. This signal is radiated from the centre of the service.
This is even more important when the signal is produced by a Sonde, lying in a large diameter
conduit!
Precautions:
Always compensate depth reading for service size.
The Locator may fail to detect electrical services in Power mode if an incorrect power setting
is used.
Precautions:
Before use, verify the Locator is setup to be compatible with mains frequency supply in your
country. Options are 50 or 60 Hz. Refer to "Appendix B World Frequency Zones" for more
information.
Contact your agency or Leica Geosystems authorised service workshop if your unit is incor-
rectly configured for your region.
Only with Transmitter:
A hazardous signal may be present on the connection plug of the Signal Clamp when clipped
over a live service.
Precautions:
The clamp should be connected to the Transmitter before clamping around a live service.
