Comfort Curve for Business Users

Designed by ergonomic experts the slight curve encourages a more natural wrist position to help reduce repetitive stress symptoms. The familiar 104-key layout feels comfortable from the first use for people accustomed to straight keyboards. It connects through a standard USB port and works with Windows 7 Vista or XP excluding 64-bit XP.

Wired USB Thermals and Power

The wired USB connection draws minimal power directly from the host computer with no external supply needed. Passive operation produces no fan noise and generates negligible heat during normal typing sessions. The slim glossy black chassis measures 18.5 by 6.89 by 1.29 inches and sits flat on the desk without a separate palm rest.

104-Key Layout Decides Fit

The single specification that determines suitability is the full 104-key arrangement including a dedicated number pad. Buyers who want a compact tenkeyless design or a separate numeric keypad should look elsewhere. The integrated media keys provide quick access to volume and playback controls without requiring extra desk space.

Questions about this item

How do I install the Comfort Curve Keyboard 3000 and what is the common mistake?

Plug the USB connector into an available port; Windows 7, Vista or XP will detect it automatically. The mistake is forcing the plug upside‑down — align the metal contacts before pushing.

What maintenance will the 104‑key Comfort Curve 3000 need over time?

Wipe the glossy black surface with a slightly damp microfiber cloth and use compressed air to clear dust from between the keys; no lubrication or internal service is required.

What limit appears first during long typing sessions on the Comfort Curve 3000?

The fixed 1.29‑inch profile and lack of a palm rest mean wrist extension becomes the limiting factor before any electronic or cable issue arises.
