system from AC outlet through power cord. Also location of fuse (F1) which protects the system from
overcurrent conditions.

42. FUSE F1 -

Provides overload protection for PRC 2000 system.

43. FOOT PEDAL RECEPTACLE -

Input for foot pedal which operates the Pik and Paste, MicroChine,

Pulse Plate or Pulse Heat features of the system as determined by the

FOOT PEDAL

Selector Switch.

This receptacle is not connected to the Thermal Management Center controls.

NOTE

The Auxiliary Power Receptacles listed below (items 44-46) will provide
temperature control for line operated auxiliary accessories or foot pedal
operation only. SensaTemp handpieces will not function properly if
connected to these outputs.

44. AUX 1 POWER RECEPTACLE -

Provides temperature control, tip ground sensing circuitry and

finger switch connection from

THERMAL MANAGEMENT CENTER

to the auxiliary accessory

connected to Auxiliary Channel 1. Foot pedal attachment to this receptacle will allow vacuum/
pressure pump operation through foot pedal actuation.

45. AUX 2 POWER RECEPTACLE -

Provides temperature control, tip ground sensing circuitry and

finger switch connection from

THERMAL MANAGEMENT CENTER

to the auxiliary accessory

connected to Auxiliary Channel 2. Foot pedal attachment to this receptacle will allow vacuum/
pressure pump operation through foot pedal actuation.

46. AUX 3 POWER RECEPTACLE -

Provides temperature control, tip ground sensing circuitry and

finger switch connection from

THERMAL MANAGEMENT CENTER

to the auxiliary accessory

connected to Auxiliary Channel 3. Foot pedal attachment to this receptacle will allow vacuum/
pressure pump operation through foot pedal actuation.

47. FUSE F2 -

Provides overload protection for
