Power on/off
Switch the locator or transmitter on by pressing the 
key.
To switch the locator or transmitter off, press and hold the key until the screen blanks off.
NOTE: The locator will automatically power off after 5 minutes if no keys are pressed.

When using active frequencies: Toggle Peak, Peak+, Null, Broad Peak and Guidance antenna modes.
In Power Mode: scroll through Power Filters™ for improved discrimination of parallel or strong signals.
In UTIL mode: Scroll through a list of utilities: GAS, TEL, SEW, TMA, H2O, PWR, EXL, IRR, CTV
With the loop folded down: toggles marker and combined (marker/line) modes.
|
In Peak+ antenna mode: Switch between Guidance and Null arrows.

Increase and decrease gain. MRX(G) automatically sets gain to mid-point when pressed.
MRX SG automatically sets gain to mid-point when pressed.
With the loop folded down only, affects the marker locator gain.

Antenna Modes
The MRX SG Marker locator supports 7 cable, pipe and marker locate modes, each of which is designed for specific uses, depending on what task is being carried out.
To scroll between locate modes, press the key.
 |
PEAK: For accurate locating, the Peak bargraph provides a visual readout of the signal strength. The Peak signal is found directly over the buried utility. |
 |
PEAK+: Choose to combine the accuracy of the Peak bargraph with Null arrows, which can indicate the presence of distortion, or with proportional Guidance arrows for rapid line tracing - switch between them by pressing and holding the key. |
 |
GUIDANCE: Proportional arrows and a ballistic directional 'needle' combine with audio left/right indication for rapidly tracing the general path of a buried utility. |
 |
BROAD PEAK: Operating similarly to Peak mode, but giving a result over a wider area. Used to detect and trace very weak signals, for example very deep utilities. |
 |
NULL: Provides a quick left/right indication of the path of a utility. As Null is susceptible to interference, it is best used in areas where no other utilities are present. |
 |
MARKER: Selected by lowering the antenna loop down, is used to locate a specific marker. |
 |
COMBINED MODE: Selected by lowering the antenna loop and by pressing the key, is used to locate a specific marker whilst tracing a buried utility. |
