Front Panel Operation
The HPAC-100/125/150/200/250-RM can be controlled locally via the front panel LCD
and pushbuttons. The unit must be in LOCAL mode for front panel operations as
explained in the Operations Menu section. The following paragraphs explain how to
operate the front panel.
Cursor Control
The cursor, which indicates the active line, is designated by the greater than sign,
“>“, in the left column of the display.
Down Arrow Key (
↓↓↓↓↓
)
This key moves the cursor between the four display lines: line 1 to line 2, line 2 to
line 3, line 3 to line 4, and line 4 to line 1. When the cursor is on a specific line, it
becomes active. The remaining keys will only function upon this active line.
Left and Right Arrow Keys (

)
These keys scroll the cursor within a line to view the different options. For example,
when in the Operations Menu, line 3 can display the attenuation level, mute status,
or remote/local control of the amplifier. The left and right arrow keys are used to
scroll through these choices to place a particular item on the display.
Plus and Minus Keys (+ and -)
These keys are used to toggle an option or increment/decrement the displayed
value. For example, if line 3 is the active line and is displaying the mute status of
the amplifier, pressing the “+” or “-” key will change the state. If the unit was muted,
pressing the key will unmute it. If the unit was unmuted, pressing the key will mute
it. Either key can be pressed when acting as a toggle. If line 3 is active and display-
ing the attenuation level, pressing the “+” key increases the attenuation level by 1 dB
while pressing the “-” key decreases the attenuation level by 1 dB.
Menus
Three different menus are available: Operations Menu (“OPS”), Status Menu (“STA-
TUS”), and Setup Menu (“SETUP”). The active menu is designated on line 4 by all
capital letters enclosed in brackets. The left and right arrow keys are used to select
the current menu mode when line 4 is the active line. The three remaining lines
have different functions depending upon the menu selection.
