Description
A
– Indicates signal attenuation is in effect due to the presence of excessive
interference, or when locating within 1 m 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
(page 25) or at the top right of the
(page 36) on the locate screen. 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 the signal
strength is flashing red, indicating the presence of extreme interference.
Page 13
– Indicates whether the receiver is currently using the Up or Down optimized
band. Located in the title bar of the Locate screen.
Page 12
– Displays after a failed calibration, often because the transmitter is too
close to the receiver.
Page 15
– 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 15
– Displays after a failed calibration. If attenuation is in effect due to
only moderate interference, the system will still calibrate; however, it is best practice to relocate to
a quieter location where attenuation is not in effect. If the signal strength on the locate screen is
flashing
red
, this indicates extreme interference, and a calibration will fail.

– 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.

– Represents the ground for the HAG function, depth readings, and the in-ground
calibration procedure.

– The locate line (LL) always displays perpendicular to the transmitter. The locate
line (LL) is found between the front and rear locate points only after a reference lock (see below)
has been obtained. May also include the transmitter yaw angle in degrees.

,
– 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 36
(the 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.

– Max Mode begins when the trigger is held longer that five seconds during a depth
reading.
Page 37
– 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 37
– Indicates that since no pitch data is currently available, the pitch is
assumed to be zero for depth, predicted depth, and AGR calculations.

– When using a fluid pressure transmitter, the number next to this icon on the Locate
screen indicates the pressure reading. If the pressure reaches an over-limit condition (from 689–
1724 kPa), the value will appear red. When the pressure reaches the overload condition (over
1724 kPa), the value will display as “+OL”.
Page 23
– Shows the remaining battery life of the receiver. Appears above the
main menu. When battery life is low, the icon will flash on the Locate screen.
Page 12
– Indicates the position of the receiver relative to the ground for the HAG function,
depth readings, in-ground calibration, and the Target Steering function.
