Dosage error while generator was
activated, where Vsns and Isns stay the
same or decrease while the ECON
increases consistently for about 150 ms.
Dosage error while activating the low 1
coag setting or either of the two high coag
settings.
Do not attempt to use the generator. Record the
number and call the Valleylab Service Center.

Dosage error detected for actual current
values while activating the bipolar mode, a
cut mode, or the low 2 or low 3 coag
setting.
Dosage error detected for actual power
values while activating the bipolar mode, a
cut mode, or the low 2 or low 3 coag
setting.
Dosage error detected for actual voltage
values while activating a cut mode, or the
low 2 or low 3 coag setting.
If the error occurs during calibration, repeat the failing
calibration step. If the number reappears, record the
number and call the Valleylab Service Center.
or
If the error occurs during normal use, do not attempt to
use the generator. Record the number and call the
Valleylab Service Center.
