• Your Nokia 20 GSM Connectivity Terminal is a product of superior design and craftsmanship and should 

be treated with care. The suggestions below will help you to fulfill any warranty obligations and to enjoy 
this product for many years. When using your terminal OR any accessory:

• Keep it and all its parts and accessories out of small children's reach.

• Keep it dry. Precipitation, humidity and liquids contain minerals that will corrode electronic circuits.

• Do not use or store it in dusty, dirty areas. 

• Do not store it in hot areas. High temperatures can shorten the life of electronic devices and warp or 

melt certain plastics.

• Do not store it in cold areas. When the terminal warms up (to its normal temperature), moisture can form 

inside the terminal, which may damage electronic circuit boards.

• Do not attempt to open it. Non-expert handling of the device may damage it.

• Do not drop, knock or shake it. Rough handling can break internal circuit boards. 

• Do not use harsh chemicals, cleaning solvents, or strong detergents to clean it. Wipe it with a soft cloth 

slightly dampened in a mild soap-and-water solution. 

• Do not paint it. Paint can clog the device and prevent proper operation.

• Use only the supplied or an approved replacement or external antenna. Unauthorised antennas, 

modifications or attachments could damage the terminal and may violate regulations governing radio 
devices.

• When dismounting the terminal from the cradle, first disconnect the power supply from the terminal.

• If the terminal or any accessory is not working properly, take it to your nearest qualified service facility. 

The personnel there will assist you and, if necessary, arrange for service.
