12. Connect a hand control to Hand Switchable
Monopolar Accessory Jack #1. Activate, one at
a time, the Cut and Coag hand switch controls
verifying that each control causes the correct indi-
cator and tone to sound. Move the hand control
to Hand Switchable Monopolar Accessory Jack
#2 and repeat.
13. Press the Monopolar Foot Switch Cut Treadle
and confirm the yellow Cut mode indicator lights
and the Cut tone sounds. While still pressing the
treadle, press the Cut mode hand switch control
and confirm that the Sabre 2400 continues to
indicate actuation of cut-mode. Cross key tone
will sound while both switches are pressed. A
very short discontinuity in the activation tone
when pressing or releasing the Hand-trol activa-
tion switch may be noticed.
14. Continue pressing the Monopolar Foot
Switch Cut treadle, and then press the Coag
mode hand switch control. A cross key tone will
sound. Release the foot switch and confirm that
the blue Coag mode indicator lights and that
the Coag tone is sounded until the hand control
switch is released.
15. Confirm that the cross key alarm tone sounds
when the Monopolar Foot Switch Coag Treadle
and the Bipolar Foot Switch are depressed simul-
taneously.
16. Remove the two wire, single pad return elec-
trode, and confirm that the Sabre 2400 beeps
twice, and the Return Monitor indicator illumi-
nates.
17. Press the Monopolar Foot Switch Cut Treadle
and confirm that a loud, steady return alarm tone
is sounded.

2.3.2 Preliminary Performance Testing

After the unit passes the Preliminary Functional
Tests of Paragraph 2.3.1, preliminary performance
testing may be conducted. Such testing is best
carried out by use of an electrosurgical generator
tester, as described in Section 4. Note that the
power display of the tester will be most accurate
when a noninductive resistor of the rated genera-
tor output impedance for the selected mode is
used.
If no tester is convenient, the availability of thera-
peutic current may be ascertained subjectively
by attempting to cut and coagulate on surrogate
tissue such as a piece of meat or fresh fruit, a
wet bar of soap, or a sponge moistened in saline.
Although not recommended, a last resort verifica-
tion of available power can be made by drawing
arcs between active and dispersive electrodes.
Due to the low voltages used in bipolar mode,
this test may not produce arcs between the tips of
bipolar forceps. Such a test will not damage the
Sabre 2400 at moderate power settings (below
half the maximum power for the mode of inter-
est) if carried out for no more than a few seconds.
However, one should expect that the electrodes
may be damaged due to the extreme temperatures
generated by the arc.
2.4 CONTROLS, DISPLAYS AND
CONNECTORS
The numbers preceding the following paragraphs
correspond to the numbered items in Figure 2.1.

2.4.1 Front Panel Controls and Displays

All controls except the power circuit breaker
are located on the control panel. Refer to the
CONTROL PANEL portion of Fig. 2.1
1. MONOPOLAR CUT MODE INDICATOR:
This lamp lights when the unit is keyed in either
monopolar cut mode.
2. MONOPOLAR CUT POWER DIGITAL
DISPLAY: Indicates the cutting power level
selected via the Cut power level controls in
the currently selected monopolar cut modes.
Calibrated in watts deliverable to rated load.
3. MONOPOLAR PURE CUT INDICATOR:
Illuminates when Monopolar Pure Cut has been
selected.
4. MONOPOLAR PURE CUT MODE
SELECT KEY: Selects the Pure Monopolar Cut
Mode by pressing and releasing the key. Pure Cut
yields minimum hemostasis and Blend Cut pro-
vides moderate hemostasis.
