MACRO_UP_BUTTON_DOWN
The macrobipolar power increment
button appeared to be pressed during
powerup.
MACRO_DOWN_BUTTON_DOWN
The macrobipolar power decrement
button appeared pressed during
powerup.
COAG_UP_BUTTON_DOWN
The bipolar power increment button
appeared to be pressed during powerup.
COAG_DOWN_BUTTON_DOWN
The bipolar power decrement button
appeared to be pressed during powerup.
Turn the power switch off (O) then on again (|). Do not press
buttons or activation devices during power up.
If the error reappears, turn off the power, disconnect the
ribbon cable that connects the front panel buttons to the
right side of the display board, and turn the power back on. If
no error appears, replace the front panel.
If the error reappears, turn off the power, disconnect the
ribbon cable that connects the display board to the control
board, and turn the power back on. If no error appears,
replace the display board.
If the error reappears, replace the control board.
133
ALL_SEAL_DEV_DATA_INVALID
On power up, the SEAL parameters in
both BATRAM and the RTC are bad.
Seal parameters loaded from defaults.
Reported to serial port only.
Replace the battery.
If the error reappears, replace the control board.
134
MN_FAILED_ATOD_TEST
Master processor detected an A/D error
during powerup.
Turn the power switch off (O) then on again (|).
If the error reappears, replace the control board.
If the error reappears, replace low voltage power supply.

If the error reappears, replace the control board.
143
144
FB_DPRAM_CAL_DATA_ERROR
Feedback processor detected corrupted
calibration data during powerup.
FB_DOSERR_MEMORY_FAULT
Feedback processor detected corrupted
memory during dose error circuit test at
powerup.
Turn the power switch off (O) then on again (|).
If the error reappears, replace the control board.
145
FB_DOSERR_TEST_ERROR
Powerup test of DOSERR circuitry
failed. Failure detected by feedback
processor.
Turn the power switch off (O) then on again (|).
If the error reappears, replace the control board.
If the error reappears, replace the high voltage power
supply.
If the error reappears, replace the RF output FET Q5 on the
RF board.
