7. Control Panel Checks:
a) Rotate the CUT and COAG power controls
CW and CCW at least one revolution (36 steps),
verifying that the associated power display
changes in one watt steps for each click of its con-
trol.
(NOTE: Displays will not decrement below zero
or increment above maximum rated power for the
selected mode.)
b) Using the MODE pushbuttons, step through
each CUT and COAG mode, verifying that the
associated mode selection indicator illuminates.
Set power to zero in each mode. Leave COAG
mode in monopolar.
(NOTE: Units not equipped with the Bipolar
option do not have COAG mode controls or
indicators).
c) Using the PAD pushbutton, verify that the
SINGLE and DUAL indicators toggle back and
forth. Verify that the RESISTANCE bar graph is
dark in SINGLE mode and that all bars are flash-
ing in DUAL mode. Verify that a "two-beep"
alarm sounds after each mode change.
d) Verify that the MACHINE indicator is dark
and that the RETURN MONITOR indicator is
lit in both SINGLE and DUAL modes.
8. Depress the Cut treadle of the foot switch.
The Return Alarm tone should sound and the
RETURN lamp should remain lit. While hold-
ing the Cut treadle, rotate the Volume Control
over its full range and verify that there is no sig-
nificant change in sound level. Release the Cut
footswitch. The tone should stop and the
RETURN MONITOR should remain lit.
9. Depress the Coag foot switch. The Return
Alarm should sound and the RETURN MONI-
TOR should remain lit.
10. On units equipped with Bipolar, select BIPO-
LAR COAG. Depress the Coag foot switch.
Verify that the Coag indicator illuminates and the
Coag activation tone sounds. While depressing
the Coag treadle, turn the Coag Power Control
clockwise. The power should increase from zero
to 5 watts. Turn the Coag Power Control coun-
terclockwise and the power should decrease to
zero watts.
11. Release the Coag foot switch. The unit
should silence. Then, select MONOPOLAR
COAG.
12. Select SINGLE PAD MODE. Connect a
non-monitoring dispersive electrode to the Patient
Plate connector; verify that the Return lamp and
bar graph extinguish.
13. Depress the Cut foot switch. The yellow
CUT indicator lamp should illuminate and the
Cut tone should sound. While Cut is activated,
rotate the VOLUME control (rear panel) over its
full range, verifying that the tone volume varies
accordingly. Set the volume to a comfortable yet
audible level.
(NOTE: At minimum volume, the activation
tones should remain audible.)
14. While continuing to press the Cut treadle of
the foot switch, depress the Coag treadle. A pul-
sating alarm tone will sound. Release the Cut
treadle, continue to press the Coag treadle and
confirm that the sound changes to the Coag tone,
and the blue Coag indicator is illuminated until
the Coag treadle is also released.
15. Activate, one at a time, the Cut and Coag
handswitch controls verifying proper actuation of
each mode.
15a. While depressing the Coag treadle (or
handswitch), turn the Coag Power Control clock-
wise. The power should increase from zero to 5
watts. Turn the Coag Power Control counter-
clockwise and the power should decrease to zero
watts.
15b. While depressing the Cut treadle (or
handswitch), turn the Cut Power Control clock-
wise. The power should increase from zero to 5
watts. Turn the Cut Power Control counterclock-
wise and the power should decrease to zero watts.
16. While the single foil electrode remains
connected, select DUAL PAD mode. Verify a
