• Do not attempt to open the unit. Non-expert handling of the unit may damage it and/or annul the warranty.
• When using regulated power supply, take notice of power voltage that must be 5V to avoid damages.
• High temperatures can shorten the life of electronic devices, and warp or melt certain plastics. Do not store the radio in
dusty or dirty areas.
