2.5 Operating Instructions
2.5.1 Preliminary Set-Up
1. Ensure the Power Switch is OFF, then connect
the power cordset to the unit and to a properly
grounded and polarized mating power receptacle.
Do not connect a Return electrode at this time.
2. Set the Power Switch to the ON position.
Within one second, the machine should respond
by:
a) Sounding each of the four tones in ascending
order over a 1 second interval.
b) Displaying all "8"s on the digital power dis-
plays.
c) Illuminating both activation indicators, all
mode indicators, both fault indicators, and all
Resistance indicator bars.
d) After the fourth tone is complete, the machine
will sound an alarm tone twice, and light the
RETURN MONITOR indicator. If the "last
used" default option is installed, the controls will
return to the settings when last activated.
Otherwise, a single zero should appear in each
power display. PURE Cut and MONOPOLAR
Coag Modes will be illuminated. The last used
PAD mode will still appear.
After two seconds, the unit is ready for use. If
the unit sounds a continuous high tone, displays
MACHINE fault, or otherwise fails to respond as
above, the unit has failed one of its internal tests
and is not ready for use. Before turning the
power off, note any "HLP" code displayed in the
power displays to assist in the diagnosis by a bio-
medical technician.
3. Inspect, then connect the desired monopolar
active accessories to the hand controlled or foot
switch controlled connectors of the electrosurgical
unit.
4. On units equipped with the Bipolar option,
connect the desired bipolar accessory to the two
blue bipolar banana jacks. Although hand
switched bipolar accessories and cords may be
used with this unit, they will be activated only
using the foot switch.
CAUTION: Always stow unused accessories
in a safe, insulated location such as a test tube
or holster.
5. Connect the foot switch to the rear of the unit
(not required if only hand switchable monopolar
accessories are to be used).
6. Inspect, then connect the plug of the dispersive
electrode cable to the return electrode jack or to
an appropriate adapter. A dispersive electrode
need not be connected if only Bipolar operation is
required.
NOTE: This electrosurgical unit incorporates
the Aspen Return Monitor. The monitor will
inhibit Monopolar operation of the unit if its
requirements for the return electrode have not
been satisfied (see instruction 8).
7. Select and prepare the patient return electrode
site and apply the return electrode in accordance
with the manufacturer's instructions. If no
instructions are given observe the guidelines pro-
vided in Section 1.1.2 of this manual.
8. Use the PAD button to select DUAL or SIN-
GLE foil Mode appropriate to the type of return
electrode connected. Confirm that the
Resistance indicator and Return Fault indicator
are blank if SINGLE foil mode is selected. If
DUAL foil mode is selected, press the MONI-
TOR Set key. Confirm the Return Fault indica-
tor is blank, and the Resistance indicator stops
flashing. The number of bars indicates the
patient's resistance and can be used as an indicator
of patient risk.
