Adjustment of LED brightness:
This section works identically to the above “Adjustment of display brightness” except that adjustment is made to
the LED brightness instead of the display.
To access this section, first press and hold the “display” button, then concurrently press “XXX” button. This can
only be done from the front panel. It is recommended that once this section is entered, that all adjustments be
made with the remote at some distance from the unit, so as not to obstruct light from reaching the sensor. LED
#2 will light, and the display will show two numbers in the range 00-15, one on the left display and one on the
right display. The left number indicates the light level that the sensor is reporting, 0 is darkest and 15 is
brightest. The rightmost number indicates the LED brightness setting for that light level, 0 is darkest and 15 is
brightest. LED#2 will be lit, which indicates that pressing the “up” or “down” buttons will adjust the LED
brightness for the current light level. Pressing button #1 will turn on LED#1, which indicates that pressing the
“up” or “down” buttons will change to a different light level setting, for which the LED brightness could then be
changed by pressing button #2. Changes to the LED brightness will only be visible for the current light level.
To exit this section, press the “display” button.
Note: Setting all brightness levels to the same value, for all light levels, will result in no change of display or
LED brightness with changes in ambient light level in the room.
Restoration of the factory default settings:
To restore the factory settings for all display settings, first press and hold the “display” button, then concurrently
press “XXX” button. This can only be done from the front panel. LEDs 1-5 will light, indicating that the unit has
restored the factory settings.
REMOTE TRIGGER
The remote trigger control allows the Pandora to control the standby state of a remote unit, such as the Atlas.
Power Amplifier. Connect the Trigger Out jack from the Pandora to the Remote Trigger jack on the receiving
device. Then turn on the main Power switch of both units. Pressing the Standby button on the Pandora should
take the other device out of Standby. Pressing the Standby button on the Pandora once more should put both
devices into Standby.
The trigger voltage of the receiving device should respond to a constant +5VDC signal.
Use a 1/8” (3.5mm) mono plug for this jack. The tip is positive and the sleeve is ground.
RS232
All functions of the Pandora can be controlled and monitored via RS232, using the DB9 connector. As long as
the rear panel power switch in turned on, the RS232 circuitry is always active, thus allowing the Pandora to be
taken out of STANDBY via RS232.
