Description

Attenuation – Indicates signal attenuation is in effect due to the presence of

excessive interference, or when locating within a few feet of the transmitter. The

receiver automatically attenuates the transmitter signal when locating at shallow

depths to reduce excessive signal strength. The A displays at the bottom-left of

the frequency optimization graph, or at the top-right of the roll indicator on the

locate screen, or beneath the Calibration Failure icon. Attenuation while locating

in close proximity to the transmitter is normal; attenuation during calibration or

frequency optimization is a warning to relocate to a location with less

interference. The receiver will not calibrate when signal attenuation is in effect. Page 16

Band Up or Down – Indicates whether the receiver is currently using the Up or

Down optimized band. Located in the title bar of the Locate screen. Page 14

Calibration Signal High – Displays after a failed calibration, often because the

transmitter is too close to the receiver. Page 17

Calibration Signal Low – Displays after a failed calibration, often because the

transmitter is not powered on or is on a different (Up or Down) frequency band

than the receiver. Page 17

Globe Icon – Shown on the receiver startup screen, the number inside (shown

blank here) identifies the regional designation, which must match that on the

transmitter battery compartment. Page 7

Ground Level – Represents the ground for the HAG function, depth readings,

and the two-point calibration procedure. Page 40

Locate Line – Represents the locate line (LL), which always displays

perpendicular to the actual transmitter. The LL is found at some location

between the front and rear locate points only after a reference lock (see below)

has been obtained. It is yellow at a distance, red when close, and black when

the receiver approaches directly over the transmitter. During target steering,

the locate line is black only. Page 52

Locating Icon (Receiver) – Represents a bird’s-eye view of the receiver. The

square at the top of this icon is referred to as the “box” in the terms Ball-in-the-

Box™ and Line-in-the-Box locating. Page 39

Locating Target Ball – Represents the front and rear locate points (FLP and

RLP). When the locate line appears, the locating ball will become a solid circle

(ball) representing the approximate locate point. Page 39

Max mode – Max mode begins when the trigger is held longer that five seconds

during a depth reading. Max mode will not engage when the roll/pitch update

meter is full (no signal loss). Page 41

Max Mode Timer – Provides a visual indication that Max mode is active (trigger

held). Replaces the roll/pitch update meter. It will remain red if no stable signal

can be found. Page 41
