front panel. Additionally, all of the analog level settings can have limits placed on them so that a casual
user canÕt set a volume at too high or low a level from the front panel.

1) Left Level Adjustment
2) Left Half-muted Level Adjustment
3) Left Treble
4) Left Bass

y) Set Real Time Clock Year (0-99) 12
i) Set Real Time Clock mInutes (0-59) 12
h) Set Real Time Clock Hours (0-23) 12
n) Set Real Time Clock moNth (1-12) 12
d) Set Real Time Clock Date (1-31) 12
o) Set Real Time Clock day of week (1-7) 12
All of these setting are adjusted by pressing the ÔSelectÕ button on the front of the AB/DR-3000. Any
setting that is not available to you (because it has been configured with a ÔfixedÕ setting or it is being
controlled from another source) will be displayed, but canÕt be changed. You can see any externally
controlled variable change as its control source alters it.
Values that can be adjusted are indicated by the flashing digits that show their current level. Once
the desired function number is displayed on the upper display, you can use the ÔupÕ and ÔdownÕ buttons
to adjust the setting as needed. Holding either of these buttons down for a moment will cause the num-
bers to automatically increment/decrement. When you are happy with the selection, pressing the
ÔSelectÕ Button until it is cleared stores the new settings permanently in the AB/DR-3000Õs nonvolatile
memory
13 . The time will only be written to the Real Time Clock chip if you have made any changes in
the clock settings.
When not being used to configure one of the AB/DR-3000Õs functions, the front panel will display a
variety of status indications. First and foremost among these is the AB/DR-3000Õs ÔheartbeatÕ. This appears
in the lower right decimal point of the seven segment ÔSelectÕ display. If the AB/DR-3000 is alive, then this
LED should be flashing at a steady rate. The same output is attached to an integrated circuit called a
Ôdead man timerÕ. If the heartbeat ever stays off for more than about a second, the dead man will reset
and restart the AB/DR-3000.
The decimal points of the other two displays show the state of the two status outputs. These are typi-
cally configured to turn ON as the left or right repeaters are playing. They can also be told to turn on,
off, or pulse at specific points as spiels are played, or at intervals controlled by the real time clock.
The number of the most recently started spiel is displayed on the front of each AB/DR-3000. This is
shown as a two digit decimal number (hexadecimal numbers are used if more than 99 spiels are loaded
on the repeater) on the two digit seven segment display.
The two modulation LEDs on the front of the AB/DR-3000 will flash along with the sound as it plays.
There is one command which can be made only from the front panel. It is used to set the card back
to itÕs default configuration. This should rarely be needed. It is invoked by holding both the up and down
buttons as the repeater is powered up.

12 Availible only if the clock option is installed. Clock can only be set if this has been enabled on the
Clock Setup menu.
