VCIVILS FCovillici vaIicly

Before	servicing	the Force 300, it is important	that you	read,	understand,
and follow the instructions supplied with the			generator	and	with any
other	equipment	used to install, test, adjust, or	repair the generator.

General Precautions

Warning: Use the generator only if the self-test has been completed as described. Otherwise, inaccurate power outputs may result.

Notice: Connect the power cord to a wall receptacle having the correct voltage. Otherwise, product damage may result.

Warning: The multipin monopolar output receptacle is designed for connecting either a handswitching (three-pin) or footswitching (one-pin) accessory, but not both at the same time. Connecting more than one accessory to the multipin receptacle will activate both accessories simultaneously.

Caution: Do not stack equipment on top of the Force 300 or place the

generator on top of electrical equipment (except the Valleylab Force GSU Unit). These configurations are unstable and/or do not allow for

adequate cooling.

Caution: Provide as much distance as possible between the electrosurgical generator and other electronic equipment (such as

monitors). An activated electrosurgical generator may cause interference with them.

Caution: Do	not turn the	activation	tone	down to an inaudible level.
The activation	tone alerts	personnel	when	an accessory is active.

Notice: If required by local codes, connect the generator to the hospital equalization connector with an equipotential cable.

Active Accessories

Caution: Accessories must be connected to the proper receptacle type. In particular, bipolar accessories must be connected to the bipolar

receptacle only. Improper connection may result in inadvertent generator activation or a REM Contact Quality Monitor alarm.

Patient	Return	Electrodes
Warning:		Using a conventional patient	return electrode	without	the
REM	safety	feature will not activate the	Valleylab REM	Contact	Quality

Monitoring System.

Using the Front Panel Footswitch for Bipolar Output

When the left (—) indicator is illuminated, the footswitch activates the instrument (handswitching or footswitching) that is connected to the

bipolar	receptacle.			(See Footswitch Activation Diagram					at	the end	of this
section.) Press			either		footswitch pedal	to activate	bipolar			output.
If you	also	connect		a	bipolar footswitch	to the rear panel, the footswitch

Receptacles		later	in	this section.

Using the Front Panel Footswitch for Monopolar Output

When the right (—>) indicator is illuminated, the footswitch activates the footswitching instrument connected to the adjacent single-pin monopolar receptacie only. (See Footswitch Activation Diagram at the end of this section.)

The front panel footswitch does not activate an instrument connected to the multipin monopolar receptacle. For information about connecting a

A patient return electrode is required for monopolar electrosurgery.

When	you	activate monopolar output, the generator connects the patient
return	electrode path.		If you	activate	bipolar output			when	a return
electrode is		applied to the patient, the generator disconnects the return
electrode path to eliminate the possibility of current dispersal.
Using a conventional patient return electrode without the									REM safety
feature	will	not activate	the Valleylab		REM	Contact	Quality		Monitoring
System.
		Valleylab		recommends		the use	of	REM	patient return
ooo		electrodes		to maximize		patient	safety.

ФЕ

REM Alarm Indicator

1 Г

For monopolar electrosurgery, connect a Valleylab REM patient return electrode to the patient return electrode receptacle.

The REM alarm indicator illuminates red until you

apply a REM	patient	return electrode	to	the patient
and connect	it to the	generator. Then	the	indicator

illuminates green. (When you connect an electrode without the REM safety feature, the indicator light is extinguished. It does not illuminate green.)

If the REM system senses an alarm condition, the indicator flashes red, a tone sounds twice, and the generator disables RF output. The indicator

illuminates red until you	correct	the	alarm condition.
When you correct the REM alarm		condition,		RF output	is enabled and
the REM alarm indicator	illuminates		green.	If you are	using a return

electrode without the REM safety feature, the red indicator light is extinguished when you correct the alarm condition.

For additional information, refer to The REM Contact Quality Monitoring System in Section 4.
