Environmental Compliance (WEEE and Packaging)
LANDI P20-R is labeled in accordance with European Directives 2012/19/EU concerning
Waste Electrical and Electronic Equipment (WEEE) and 2013/56/EC concerning Batteries
and Accumulators. Those provisions are requiring producers and manufacturers to become
liable for take-back, treatment and recycling upon end of life of equipment and batteries.
The crossed-out wheeled bin symbol on the product or accessories
indicates it is considered electronic equipment waste (WEEE) which
must be properly disposed of and should not be thrown away. Spent
batteries must also be collected separately for recycling.
Please contact your retailer for more details on the take-back and recycling program in
place for disposing of old equipment and batteries. Participating ensures their responsible
re-use and recycling, which benefits both the environment and human health.
The Green Dot symbol on the packaging confirms it complies with
Directive 94/62/EC concerning packaging and packaging waste.
Packaging bearing this symbol must be returned through collection
schemes managed by accredited Green Dot organizations for recovery
and recycling.
RF Compliance
The functions of Wireless Access Systems including
Radio Local Area Networks (WAS/RLANs) within the
band 5150-5350 MHz for this device are restricted to
indoor use only within all European Union countries
30
Accessibility Compliance
The physical keyboard features a 12-key layout complemented by three function keys. The
number 5 key, positioned at the center of the keypad, is equipped with a prominent Tactile
Bump to enhance the user's tactile recognition capabilities, ensuring compliance with
Accessibility standards.
This design provides excellent Tactile Recognizability. The bumped center key serves as
a physical reference point, helping users quickly differentiate the function keys. This fulfills
the requirement for "tactile discernibility" as stipulated in accessibility directives EN 301
549 and EU 2019/882. As a result, this design enables users with visual impairments or
low vision to accurately identify key positions by touch, eliminating the need for visual
operation and thereby enhancing the product's operability and inclusivity.
