10. Operation
• Power switch - When the power switch is engaged, the CA6.4 power indicator will be lit an amber color. The
CA6.4 should be left on at all times. The unit will consume very little power unless the zones are on and
active. The unit has a stand-by mode when the zones are inactive.
• The zone indicator will light either red for off or green for on. The zones can only be turned on from the key-
pads. All functions are accessed through the keypad only.
Operating The CA6.4 Keypad
• Power ON / OFF - This knob on the CA6.4 keypad controls all functions except
for the IR management. To turn the unit on, simply turn the control knob clock-
wise. 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 zone
is On or Off.
• Volume UP / DOWN - Once the unit is on, the knob can be used to adjust the
volume. To adjust the volume up, turn the knob clockwise, and to turn the vol-
ume down, turn counter-clockwise.
• Source Selection - By pressing the knob, the zone will scroll through the four
sources connected to the CA6.4. The keypad has four lights (LED's) that indicate
the source selected.
• IR Source Control - The IR window repeats all source commands from the
source component's remote through the CA6.4 and 845 emitters. Most IR
receivers have a range of 20' at an angle of 60-65 degrees.
