Model 5000A225A
12 Rev B
2.4.1 Local Control Interface
This section describes local operation of the Model 5000A225A using the human interface items found on the
control panel.
2.4.1.1. Keylock Switch
The Keylock Switch is provided for protection from unauthorized use or unexpected remote control of the
Model 5000A225A. The Model 5000A225A can only be turned on locally when the Keylock Switch is in the
LOCAL position. Likewise, the unit can only be turned on or controlled remotely when the Keylock Switch
is in the REMOTE position. Placing the Keylock Switch in the INHIBIT position places the Model
5000A225A into an RF off state and prohibits any control of the Model 5000A225A. All remote queries are
processed and responded to in any of the three Keylock switch positions.
2.4.1.2 Power Button
The momentary POWER button turns the main power to the Model 5000A225A on and off. The status of the
green light-emitting diode (LED) in the switch indicates whether the Model 5000A225A’s power is on or off.
The main power supply fans are active when power is on. The LCD touch display is active as long as the
main circuit breaker for the Model 5000A225A power entry module is on.
2.4.1.3 Adjust Knob
The ADJUST knob is used to set the value of several parameters available through the touch screen menu
options. These parameters are RF Gain, ALC Threshold, ALC Detector Gain, and ALC Response. The
Select Menu is used to select which parameter the ADJUST knob will adjust. The range of RF Gain, ALC
Threshold, and ALC Detector Gain is 0 to 100 percent. The range of the ALC Response is 1 to 7. The
ADJUST knob can be rotated both clockwise and counterclockwise 360 degrees.
2.4.1.4 Touch Screen
The touch screen is a color LCD that can accept single touch events from soft blunt objects such as a human
finger. The mechanism that registers touch events is resistive based and relies on pressure not capacitance.
Menu options presented on the touch screen are typically gray in color with a black text label in the center.
When a valid touch event is registered a thin black box appears around the valid touch location and an
optional audible beep will occur.
2.4.1.5 Menu Map
Figure 2-5 shows the menu map for the Model 5000A225A. The screens depicted are only example screens.
The actual values and settings will be different on the actual amplifier depending on user settings and
operating conditions.
