11、 the BAND key. All functions are initialized and activated in the all light-ing mode. All lighting mode is canceled when any main unitskeys are pressed. The normal display obtained whenthe selector is set to TUNER then appears. E2PROM check(Etype only).Check the reading data and the writing data of
12、theE2PROM after setting the test mode.Display shows blank if the reading data and writingdata are the same. Display shows “LW“ if the differentdata will be written to E2PROM.3-4 ACTIVE CONTENTS The mute control is not activated when the mode isswitched. The test mode will be terminated by plugging i
13、t off thepower source or by initializing it when all the settingswill be initialized. During the test mode, it can be operated in a specialmanner that is deferent from an ordinary operation byusing the keys on the remote control or the main body,specifically as shown in the following table (3-5 CON-
