Logitech CORDLESS DESKTOP MX 5000 LASER - Manual (Page 24)

Laser illumination reveals structure that an LED simply cannot express. The coherent nature
of laser light creates patterns of high contrast when its light is reflected from a surface. The
pattern appearing on the sensor reveals details on any surface, even glossy surfaces that would
look totally uniform when exposed to the LED incoherent illumination (Figure 4). The precision
image sensors then have no difficulties in tracking on these patterns and calculating position and
movement. This is how laser enables tracking on virtually any surface.

6.2 Could the Laser Engine harm me?
A quick look around any home reveals lasers improving our lives. From CD and DVD players to
printers and handheld pointers, lasers designed for consumer use offer enormous benefits and a
high degree of safety. But lasers also conjure up images of destructive ray guns, a staple of
science-fiction movies. Fortunately, that’s not the case with Logitech’s laser mouse technology.
Logitech’s laser mice are perfectly safe for consumers, earning a Class I eye-safe designation. After
all, transmitting a beam of light for the tiny distance required, less than an inch, requires only a
minuscule amount of power.
6.3 How long does it take to recharge the mouse?
It takes only 10 minutes of charging to provide enough power for one full day of use. It takes
approximately 4 hours to fully charge the MX 1000.
6.4 How long can I use the mouse once it’s fully charged?
The mouse has an autonomy of approximately 15 days. This number may vary depending on the
activity level. It takes only 10 minutes of charging to provide enough power for one full day of use.
It takes approximately 4 hours to fully charge the MX 1000.
6.5 Does it harm the mouse to leave it on the cradle?
No, the charge algorithm will detect the end of charge and then conserve the full battery charge
without over-charging. Just make sure the power-brick stays powered as long as the mouse
remains on the cradle, otherwise the batteries will discharge again.
