2 vLoc3 Series Receivers

Backlight

– Press the Enter key to change the backlight intensity to Low, Medium, High, or Auto. The use of the “Auto”

selection is recommended because the receiver has a built-in light sensor that automatically adjusts the backlight intensity to the
surrounding lighting conditions. Auto-selection may improve battery life performance.

Sound Configuration

- Changes the sound configuration of the locate modes. Use the Enter key to select

• When in active locate modes:

- Frequency Modulated (

) Sound pitch changes with signal strength

- Amplitude Modulated (

) Sound volume changes with signal strength

• When in passive locate modes:

- Radio mode:

Real

(Sound derived directly from the received signal)

- Power mode:

Real

Imperial/Metric

– Use the Enter key to select Imperial or Metric measurements for the depth readings.

Continuous Info

– The locate screens can display a continuous reading of either depth, current, both, or can be switched off.

Use the Enter key to select your preference.

Auto Power Off

– The unit can be set to switch off after a set time. Options are 5-minutes, 10-minutes, or Never. Note that

when the accessory A-frame is connected, the timer defaults to “Never.”

2.4.2

Setup - Operational

Frequency

- Press the Enter key to enter the Frequency sub-menu. Scroll up and down the table of available frequencies

using the “+” and “-” keys.

TIP

Simplify the operation of the receiver by selecting only the frequencies applicable to your application.

To do this, use the enter key to check the boxes on the right. Frequencies not checked will not appear

on the locate screen.

Frequency

8.01kHz
8.19kHz
8KFF
8.44kHz
9.50kHz
9.80kHz

9.82kHz

10.0kHz

NOTE

Certain frequencies have an A-frame icon next to them. This icon indicates that these frequencies are

selected to be used with the fault find A-frame.

Classic Locate

– This option is only shown if the menu is entered from the Classic Screen.

Use the enter key to reveal the list of options relating to the Classic Locate mode. Options are:

Classic Locate

Peak

Peak With Arrows
Null
Broad
Delta Null
Omni Directional Peak
