If condensationoccurs, correct operation may not be possible, or the unitmay not function correctly.This is not a malfunction, however, and the unit should bedried.(To do this, turn the POWER switch ON and leave the unitas it is for several hours.)Be especially careful in the following conditions: When the unit is brought from a cold place to a warm placeand there is a large temperature difference. When a heater starts operating. When the unit is brought from an air-conditioned place toa place of high temperature with high humidity. When there is a large difference between the internaltemperature of the unit and the ambient temperature, or inconditions where condensation occurs easily.DM-SE7/SE7(G)/SE92CONTENTS / ACCESSORIES / CAUTIONSCONTENTS / ACCESSORIES / CAUTIONS.2CIRCUIT DESCRIPTION.3PC BOARD . 6SCHEMATIC DIAGRAM . 9EXPLODED VIEW .19PARTS LIST.21PARTS DESCRIPTIONS .27SPECIFICATIONS .Back coverAudio cord(E30-0615-05)AccessoriesContentsBatteries (2)Remote control unit(A70-1153-05) : RC-MSE7(A70-1169-05) : RC-MSE9Battery cover (A09-0129-08 : RC-MSE9)(A09-0356-08 : RC-MSE7) System control cord(E30-2628-05)Optical fiber(B19-1529-05)AC plug adapter(E03-0115-05)CautionsNote related to transprotaion and movementBefore transporting or moving this unit, carry outthe following operations.1.
