Using the Locator:

Automatic Daily Self Test

The CXL2, DXL2 AND MXL2 Locators have an in-built automatic Daily Self Test function.
This tests the Locator’s circuits and receiving aerials for correct performance.

The Self Test is automatically performed the first time the Locator is switched on each day
and takes approximately four seconds. The Locator will then be ready for use.

The Self Test process is indicated by ‘

’ appearing on the display.

In the top left hand corner of the screen a countdown timer shows
the progress of the test.

NOTE When turning the Locator on for the first time it is important that no Signal Generators, Transmitters
or Sondes are operating within 5 metres of the Locator.
NOTE Try not to switch the Locator on for the first time in an area with unusually high Power signals such
as next to an electricity transformer.
