11.2 Operating the CA KP Keypad (See Figure 4)
1) Power On / Off: This knob on the CA KP keypad controls all functions except for the IR management. To turn the unit on, simply
turn the control knob clockwise. You will feel and hear a click verifying that the unit has been activated. The lights on the keypad
will also illuminate to verify the zone is now on. Note - The CA6.4 front panel zone-management lights also informs you which

lights (LED's) that indicate the source selected.
4) IR Source Control: The IR window repeats all source commands from the source component's remote through the CA6.4 and 845.1
emitters. Most IR receivers have a range of 20' at an angle of 60-65 degrees.
11.3 Operating the CA-LCD Keypad (See Figure 5)
1) Display: The LCD panel displays the source selected and the volume level.
2) Source: The source button is pressed to select one of the four sources to listen to. Press the source button until the desired source is
selected. The source will be displayed on the LCD display panel.
3) Store: The store function is used to select and store one of the 23 preset source names for each of the four sources. Select the source
name that you want to change by selecting source. Press and hold the store button for approximately 3 seconds, and the display
begins to flash. Immediately press the UP/ DOWN volume buttons to select the different source names. After you have selected the
name, press the store button again.
4) Volume Up/Down: The UP/ DOWN arrows for volume are used to select the volume level and to select a different source name
after the store button is pressed. If the button is pressed and held the volume will ramp up or down.

or green by pressing and holding the button. The backlight will change from one color to the other.
7) IR confirmation LED: This LED will flash to confirm the reception of an IR signal from a remote control through the IR receiver.
8) IR receiver: The IR receiver is used to receive commends from an IR remote control. Remote controls used for the source equipment
will pass through to the main controller and on to the source equipment. The center frequency for the IR receiver is 40KHz. It will
receive IR signals from 38KHz to 42KHz. To control the functions of the CA-LCD keypad, use the CA Remote control (see Figure 6).
The CA remote control will operate the lamp, source selection, volume up / down and room on / off.
