faulty, and consequently:
aspiratory O2 measurement faulty.
Call DrägerService.
CO2 INOP !
CO2 gas measurement faulty. Call DrägerService.
CO2 LINE? !
Sample line blocked. Check sample line, filter in T-piece and
water separator; replace if necessary.

high or fan for mixer electronics is
defective.
Clean filter on the back panel.
Call DrägerService.
EMERGENCY O2 OPEN !
O2 emergency metering has opened in
normal operation.
Close O2 emergency metering.
ET CO2 > !!
Upper alarm limit for end-expiratory
CO2 concentration has been exceeded
for at least two breaths.
Check ventilation.
ET CO2 < !!
End-expiratory CO2 concentration has
fallen below lower alarm limit for at least
two breaths.
Check ventilation.
FI HAL > !!!
FI ISO > !!!
FI ENF > !!!
FI DES > !!!
FI SEV > !!!
The inspiratory gas concentration of the
relevant anaesthetic agent exceeds the
upper alarm limit.
The upper alarm limit has been
exceeded for at least two breaths.
Check setting of anaesthetic vaporizer.
FI HAL < !!
FI ISO < !!
FI ENF < !!
FI DES < !!
FI SEV < !!
Inspiratory gas concentration of the
relevant anaesthetic agent is below the
lower alarm limit.
The value has remained below the lower
alarm limit for at least two breaths.
Check setting of anaesthetic vaporizer.
FI O2 < !!!
Inspiratory O2 concentration is below
the lower alarm limit.
Check O2 supply.
Check O2 concentration in fresh gas
flow.
FI O2 > !!
Inspiratory O2 concentration exceeds
upper alarm limit.
O2 flush used.
Check O2 concentration in fresh gas
flow.
FI O2 INOP !
Aspirating O2 measurement defective. Call DrägerService.
O2 sensor exhausted. Replace O2 sensor, page 117.
O2 sensor not used. Use O2 sensor, page 117.
FLOW INOP !
Flow sensor defective. Replace flow sensor, page 106.
GAS FAILURE !!!
Failure of the O2 and AIR supply. Open backup O2 cylinder.
Check connection to central supply.
INSP CO2 > !!
The inspiratory CO2 concentration
exceeds the fixed upper limit of 5 mmHg.
Replace the soda lime in the anaesthetic
unit system.
Valve discs in breathing system
defective.
Set sample rate to 200 mL/min due to
high frequency and time constant of
CO2 sensor.
