The HA30AR-WC & HA60AR-WC Mini-Argos Remote Controlled Surgical Light is a sophisticated lighting system designed for surgical environments, offering precise control over light intensity and positioning. This system comprises a lighthead with optical sensors and computer circuitry, a hand-held wireless remote control unit (positioning wand), and a wall-mounted control panel.
Function Description
The Mini-Argos Surgical Lighting System provides high-frequency strobe light for illumination during surgical procedures. The lighthead is positioned by means of a hand-held wireless remote control unit, which emits a bright, high-frequency strobe light. Photoelectric elements located in the lighthead sense the signal emitted by the wand and create input signals to the internal computer circuitry. This circuitry simultaneously activates two positioning motors, directing the light beam to focus precisely on the positioning wand. The ON-OFF switch and light intensity controls are located on the wall control. The wall control also offers positioning back-up.

Usage Features
- Wall Control: The wall-mounted control features an "ON-OFF" switch, which supplies direct power to the Mini-Argos positioning circuitry. The intensity control knob regulates input to the bulb circuit. A "LIGHT SELECT" switch allows selection of the main power or a backup light source.
- Positioning Wand Operation: To initiate positioning, the lighthead turns the main power switch "ON" and holds the strobe end of the positioning wand in the light beam path. Pressing the momentary switch button on the side of the wand activates the lighthead. The light beam moves to the desired position and releases the switch. The positioning wand can be repositioned as required during surgery. Holding the strobe end of the control wand in the light path, pressing the switch button, moves the wand to the new position and releases the switch.
- Battery Indicator Light: A battery indicator light located on the wand will go "ON" when the button is pushed. If the button is pushed and the red light gets dimmer or goes out, the batteries need to be changed.
- Bulb Voltage Adjustment: To ensure maximum intensity and to prolong bulb life, the voltage to the bulb should be 20VAC. This can be adjusted by turning the adjuster clockwise to increase the output voltage, or counterclockwise to decrease the voltage. Proper voltage should be 20V.
- Intensity Control: The intensity control knob on the wall panel adjusts the light output. The voltage adjuster is located on the back of the intensity control. Wall control must be removed from switch box to make the adjustment.
Maintenance Features
- Positioning Wand Batteries: The positioning wand is powered by two C-size alkaline batteries. If the lighthead fails to follow the wand correctly or symptoms of low battery voltage are observed, the batteries need to be replaced. To replace, slide the battery cover toward the end of the main case and remove it. Install two new C-size alkaline batteries, ensuring correct polarity.
- Positioning Wand Strobe Bulb: To replace the strobe bulb, unscrew and remove the bulb cover. Hold the bulb by the base and pull straight out. Insert the new bulb by holding it by the base and pushing it straight in.
- Halogen Bulb Replacement: To replace the halogen bulb, loosen the thumbscrew securing the diffuser cover and lower the cover. Remove the two thumbscrews securing the filter assembly and remove the filter assembly. Make sure the electrical power to the fixture is "OFF" and the bulb is cool. Using caution not to touch the reflector surface, hold the bulb by the base and pull out. Slightly working the bulb back and forth may aid in removal. Insert the new bulb by holding it by the base and pushing it straight in. Align the three prongs on the new bulb with their corresponding contact holes in the wand (pins are arranged so bulb will fit properly in only one position) and push new bulb into place. Replace bulb cover.
- Note: Halogen bulbs are sensitive to body oils. Do not handle glass surface of new bulb, as body oil from fingers can create a "hot spot" and may cause the bulb to burn out prematurely.
- Cleaning:
- Lighthead Exterior: Should be wiped down periodically or between cases with a mild cleaning agent that will not adversely affect painted or plastic surfaces.
- Lighthead Interior: Should be cleaned once a year or as applicable.
- Filter: Should be removed periodically to remove dust and lint. Dust off with a dry cloth or wash and air dry as desired. The diffuser can be cleaned using a "plexiglass" cleaner such as "210 Plus Cleaner and Scratch Remover" available from Summer Labs (1-800-542-8656, Fax 617-482-9001) or equivalent. Do not use alcohol-based cleaners on the diffuser.
- Moving Parts: During scheduled cleaning of the lighthead interior, all moving parts should be lubricated.
- Service: For factory service or preventive maintenance contracts, contact SKYTRON Mini-Argos lighting systems.
- Testing: If the light fixture does not function properly, test the lighthead wiring at the wire connections in the lighthead junction box for proper voltages.
Special User Attention
- To help assure the highest degree of operating safety for user and patient, SKYTRON has provided precautionary instructions throughout this manual.
- As with the operation of any surgical light, all hospital personnel should be aware that a certain amount of care must be exercised to maintain patient safety and to keep your SKYTRON light fixture performing at peak efficiency.
- The following is a summary of the important precautionary instructions:
- Make sure the electrical power to the fixture is "OFF" and the bulb is cool. Using caution not to touch the reflector surface, hold the bulb by the base and pull out.
- To prolong bulb life, the Sof-Start bulb protection circuit will cause a slight delay before the bulb will illuminate.
- Halogen bulbs are sensitive to body oils. Do not handle glass surface of bulb as body oil from fingers can create a "hot spot" and may cause the bulb to burn out prematurely.
- Voltage adjuster is located on the back of the intensity control. Wall control must be removed from switch box to make the adjustment by an authorized service person.
- Equipment not suitable for use in the presence of flammable anaesthetic mixture with air or with nitrous oxide.
- Where applicable - remove batteries if equipment is not going to be used for some time.
- Warning - risk of fire, replace with 24V 100W Tungsten Halogen Lamp.
- Warning - for continued protection against risk of fire, replace only with same type and rating of fuse.
- Caution - before operation remove top cover, discard packing material and verify that all circuit boards are in place.
- Notice - Thermally protected fixture. Blinking light may indicate insulation too close to fixture or fixture installed where spacings are less than those specified.
- It is recommended to keep the equipment away from disturbance sources including electromagnetic fields in order to avoid malfunctioning of the equipment.
- A dedicated circuit & circuit breaker is required for fixture.
