1. Introduction
1.1. General Care and Maintenance
Your device is a product of superior design and craftsmanship and should be treated with care.
The following suggestions will help you.
•Keep the device dry. Precipitation, humidity, and all types of liquids or moisture can contain
minerals that will corrode electronic circuits. If your device does get wet, allow it to dry completely.
•Do not use or store the device in dusty or dirty areas. Its parts and electronic components can be
damaged.
•Do not store the device in hot areas. High temperatures can shorten the life of electronic devices,
damage batteries, and warp or melt certain plastics.
•Do not store the device in cold areas. When the device returns to its normal temperature,
moisture can form inside the device and damage electronic circuit boards.
•Do not open the device while power is on. Otherwise electrical shock may result.
•Do not drop, knock, or shake the device. Rough handling can break internal circuit boards and
fine mechanics.
•Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the device.
•Do not paint the device. Paint can clog the parts and prevent proper operation.
•Unauthorized modifications or attachments could damage the device and may violate regulations
governing radio devices.
These suggestions apply equally to your device, battery, charger, or any enhancement. If any device is
not working properly, take it to the nearest authorized service facility for service.
Regulatory information
Disposal of Waste Equipment by Users in Private Household in the European Union
This symbol on the product or on its packaging indicates that this product must not be
disposed of with your other household waste. Instead, it is your responsibility to dispose
of your waste equipment by handing it over to a designated collection point for the
recycling of waste electrical and electronic equipment. The separate collection and
recycling of your waste equipment at the time of disposal will help to conserve natural
resources and ensure that it is recycled in a manner that protects human health and the
environment. For more information about where you can drop off your waste equipment
for recycling, please contact your local city office, your household waste disposal service or the shop
where you purchased the product.
We hereby declare that the product is in compliance with the essential requirements and
other relevant provisions of European Directive 2014/53/EU (Directive on the
harmonisation of the laws of the Member States relating to the making available on the
market of radio equipment and repealing Directive 1999/5/EC).
