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, 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 attempt to open the device.
•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
