SubSurface Instruments AML PRO Operator's Manual page 7

1) EASY BATTERY ACCESS
The AML Pro is powered by either a convenient 9-volt battery
system (1), or by a rechargeable lithium battery pack (1a).
2) ERGONOMIC HANDLE
The ergonomically designed handle allows the operator to hold the
AML Pro for extended periods of time in all weather conditions.
3) CONTROL PANEL
There are six function buttons on the AML Pro control panel, these
buttons will provide you with the ability to navigate through the
Menu Screen, as well as having access to the many features on
your AML Pro Unit. Functions include: ON/OFF, TX (Transmitter),
MENU, DOWN ARROW, UP ARROW, SEL (Select).
4) RIGHT SIDE & LEFT SIDE TARGET INDICATORS
LED target indicators identify when an object has been located,
signifying that the object is parallel with the AML Pro. Digital target
indicators are displayed at the bottom of the main screen on
the LCD digital display and work in unison with the right and left
receivers to indicate an object's presence, and to place its location.
5) DIGITAL BACKLIT DISPLAY
A high contrast, backlit digital display provides superior visibility in
both direct sunlight and dark environments.
6) LIGHTWEIGHT, DURABLE CONSTRUCTION
The electronic circuitry of this unit is housed in a tough, water-
resistant, high-impact ABS enclosure. This enclosure helps to
protect the sensitive electronic components. It does not protect the
unit from abuse or careless misuse. Treat this unit as a scientific
instrument. Keep it stored in the foam-insulated case when not in
use.
7) ULTRA-HIGH FREQUENCY (UHF) RADIO TRANSMITTER
An UHF transmitter delivers the intensity of the UHF signal as it is
aimed at its intended target.
