54 Care and Maintenance Care and MaintenanceKeep the scanner dry. If it gets wet, wipe it dry immediately. Use and store the scanner only in normal temperature environments. Handle the scanner carefully: do not drop it. Keep the scanner away from dust and dirt, and wipe it with a damp cloth occasionally to keep it looking new. General Use • Turn the scanner off before disconnecting the power. • Always write down the programmed frequencies in the event of memory loss. • If memory is lost, simply reprogram each channel. The display shows 000.0000 in all channels when there has been a memory loss. • Always press each button firmly until you hear the entry tone for that key entry. Location • Do not use the scanner in high-moisture environments such as the kitchen or bathroom. • Avoid placing the unit in direct sunlight or near heating elements or vents. • If the scanner receives strong interference or electrical noise, move it or its antenna away from the source of the noise. If possible, a higher elevation might provide better reception. • Also try changing the height or angle of the antenna. Cleaning • Disconnect the power to the unit before cleaning.
