Keypad actions & shortcuts

Locator key actions

Key	Short press	Long press
	Enter the menu	Switch power off.
	Scroll through locate frequencies from low to high
	When using active frequencies: Toggle Peak, Peak+, Null and Guidance antenna modes. In Power Mode: scroll through Power Filters™ for improved discrimination of parallel or strong signals.	In Peak+ antenna mode: Switch between Guidance and Null arrows.
	Increase and decrease gain. RD7200 automatically sets gain to mid-point when pressed.	Rapidly increase and decrease gain steps in 1dB increments.

Transmitter key actions

Key	Short press	Long press
	Enter the menu.	Switch power off.
	Scroll through locate frequencies from low to high.
	Take voltage and impedance measurements using selected frequency.	Take voltage and impedance measurements at a standardized frequency.
	Adjusts the output signal.	Select standby /maximum standard power.

NOTE: to scroll through frequencies from high to low, hold while pressing the button (applies to both locators and transmitters).

Antenna Modes

The RD7200 locator supports 4 antenna modes to suit your particular application or the local environment.

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.
	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.
