The Welch Allyn GS 900 is a medical examination light designed for use on a mobile stand, providing illumination for various medical procedures. The assembly instructions detail the process of setting up the device, from unpacking to final operation.

Function Description:

The GS 900 serves as a general examination light, offering bright and focused illumination. Its primary function is to provide optimal visibility for healthcare professionals during patient examinations and minor procedures. The light head, or luminaire, is equipped with multiple LED light sources, ensuring a broad and even light field. The mobile stand allows for easy positioning and maneuverability within a clinical setting, adapting to different examination needs and room layouts. The design incorporates features for adjusting the light's position and angle, ensuring the light can be directed precisely where needed.

Important Technical Specifications:

While specific technical specifications like light intensity (lux), color temperature (Kelvin), or power consumption are not explicitly detailed in the provided pages, the visual evidence suggests it uses LED technology, which is known for its efficiency, long lifespan, and consistent light output. The device is designed to be powered via a standard electrical outlet, as indicated by the power cord and wall plug connection. The mobile stand features four wheels, two of which are equipped with brakes, providing stability and controlled movement. The overall construction appears to be robust, utilizing materials suitable for a medical environment, likely including durable plastics and metal components for the stand and arm. The light head itself features a ventilated design, suggesting heat dissipation mechanisms for prolonged use.

Usage Features:

The GS 900 is designed for ease of use and flexibility.

Mobility: The mobile stand with four wheels (two with brakes) allows for effortless relocation and secure positioning. This is crucial for dynamic clinical environments where the light may need to be moved between examination rooms or adjusted frequently during a procedure.
Adjustability: The light is mounted on an articulated arm, which can be adjusted in height and angle. The instructions show the process of loosening and tightening screws to facilitate these adjustments, indicating that the arm can be securely fixed in various positions. This ensures that the light can be precisely aimed at the examination area, minimizing shadows and maximizing visibility.
Intuitive Controls: The light is turned on via a simple button on the luminaire, suggesting straightforward operation.
Ergonomic Design: The light head features handles (blue accents) for easy manipulation and positioning, enhancing user comfort and control.
Quick Setup: The assembly process, as illustrated, is designed to be relatively straightforward, involving connecting modular components like the stand base, pole, arm, and luminaire.

Maintenance Features:

The provided manual pages primarily focus on assembly, but some aspects hint at maintenance considerations:

Modular Design: The device appears to be constructed from several distinct modules (stand base, pole, arm, luminaire), which could simplify potential repairs or replacement of individual components.
Protective Covers: The instructions show the removal and discarding of grey protective covers from the arm and luminaire during assembly. This suggests that these covers are in place to protect sensitive components during shipping and storage, ensuring the device arrives in pristine condition.
Tool Requirements: The manual explicitly states "Tools not included" and illustrates a Phillips/plus-slotted screwdriver and a slotted/minus screwdriver. This indicates that basic hand tools are required for assembly and potentially for routine adjustments or minor maintenance tasks. The inclusion of a retaining ring and a tool for its installation suggests that certain connections are designed for secure, long-term fastening, but may require specific tools for disassembly if maintenance is needed.
Electrical Connection: The power cord is detachable from the unit, which is a common feature for safety and ease of replacement if the cord becomes damaged.

In summary, the Welch Allyn GS 900 is a mobile examination light characterized by its robust design, ease of assembly, and flexible positioning capabilities, making it a practical illumination solution for various medical settings.
