This unit contains a control circuit
board and an antenna circuit board
which directs the center transmitter
as well as independent left and right
signal receivers.
A powerful 2.45 Ghz radio frequency
locates density differences thru the
transmission and reception of UHF
signals.
The unit locates objects by analyzing
differences in material densities.
Objects or geometries create phase
differences in the return signal, which
are then interpreted by the highly
advanced circuitry.
HOW THE AML PRO WORKS
User Reference - Scanning QR Codes
The AML Pro has several QR Codes placed on the blade’s face.
Scan these codes for more operator information, and for continu-
ing updates provided by the manufacturer. AML Pro additional
information can be accessed from your smart phone using a stan-
dard QR code App. For more information on how to download and/
or use a QR code App., visit the App. store on your smart phone.

> TIME ZONE SET
Use the UP ARROW or DOWN
ARROW Buttons to scroll through the
dropdown menu.
Set the TIME ZONE SET to local time.
Setting the TIME ZONE SET utilizing
the Time Zone Set Table (gure 17-1)
will provide the unit with accurate local
time within the Time Zone that the unit
is operating.
The AML Pro maintains a Real Time
Clock (RTC), that can be automatically
synchronized to Global Positioning
System (GPS) time. RTC is the user’s
local time while GPS is referenced to
Universal Time Coordinated (UTC)
based in Greenwich, England.
There are 24 Time Zones. Find the
zone in which the unit will be operating
(see gure 17-1) and enter the time
off-set value from the Time Zone Set
vs. Local Time Table. After the Time
Zone Off-set value is entered and
saved, the RTC will be updated the
next time a GPS signal is acquired.
For those parts of the world with
a nonstandard off-set (30 or 45
minutes), the local clock time
synchronizing can be disabled by
entering a value of 24 into the TIME
ZONE SET.
The AML Pro does not automatically
shift the off-set for Daylight Savings
Time, add one(1) to your Time Zone
Set to adjust the time manually. This
time change will have to be re-entered
manually to come back from Daylight
Savings Time. The TIME ZONE SET
will have to be reset if the AML Pro
is transferred for use in other time
zones.

EVENT MESSAGES
POWER EVENTS
USB PWR (Universal Serial Bus Power)
The USB PWR indicates when the
auxiliary battery pack is connected to
the AML Pro. Turn the AML Pro Unit
OFF before connecting the external
battery pack. Generally the auxiliary
battery pack will provide 12 hours
or more of continuous operation.
It’s recommended to use the AML
Pro with fresh 9-volt batteries in the
battery holder for back up.
BAT PWR (Battery Power)
The BAT PWR event indicates that the
AML Pro is operating on the internal
alkaline batteries.
LOW BAT (Low Battery)
The LOW BAT event indicates that
the internal alkaline batteries are
becoming too weak. The LOW BAT
event indicator applies only to the
alkaline battery sleeve located in the
handle of the AML Pro. The external
battery pack will shut the unit off
without a warning, that’s why is
recommended to have a fresh 9-volt
battery sleeve in the AML handle.
AML OFF (AML Pro Shutdown)
The AML Pro will automatically shut
down once the LOW BAT condition
drops the supply voltage below 6.5v
DC. All data previously recorded
prior to shutdown will be preserved in
memory. 19

LOGGING EVENTS (GPS)
SATS (Satellites)
The SATS line indicates the number
of satellites in which the AML Pro is
communicating. To increase the level
of accuracy it is preferable to use 7 or
more satellites.
LOGGED (Logged Information)
A LOGGED event indicates that
information has been stored into the
memory of the AML Pro. The screen
will display a NO LOCK message if
less than 3 satellites are found. A LOG
is a “Snap Shot” of the information
recorded by the AML Pro thus far. This
information is recorded and indexed
by the memory, every time the SEL
button is pressed. It includes longitude
and latitude coordinates, day-month-
year, hour-minute-second, and the
number of communicating satellites.
FULL (Memory Full)
The AML Pro memory can store up to
300 records. A FULL event indicates
that the memory is full and no more
information will be recorded. A FULL
event will be accompanied with an
audible alert and a fault message in
the STATUS Line. When the memory
is full, the operator can either connect
the AML Pro to a computer and
download the information, thereby
emptying the AML Pro memory, or
DISCARD records to make room for
more.
DISCARD (Delete Information)
Press and hold the SELECT Button
for three seconds to delete the last
recorded information. You can Discard
information at any point while in GPS
Mode, even when the memory is not
full. Once all information has been
deleted, the screen will display an
EMPTY message in the STATUS line.
