[. . . ] If you experience a ringing in your ears, reduce the volume level or discontinue use. AVOID using or placing the receiver in direct sunlight or in areas with temperatures below ­10°C (+14°F) or above +60°C (+140°F). Even when the receiver power is OFF, a slight current still flows in the circuits. Remove batteries from the receiver when not using it for a long time, otherwise, the installed batteries will become exhausted. [. . . ] For programmed scan, scan edges must be programmed in advance. Program scan edges in the same manner of programming a memory channel (p. 21) A tone scan function is available to search for subaudible tones (e. g. when you want to find a subaudible tone frequency necessary to open a repeater or to open the tone squelch). 30 for details.
