Ex. 1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). 560 = 56 × 101 = 561 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

RS1P 1 Â 0 K Ex. 2 When there are 3 effective digits (such as in high precision metal film resistors). ANALOG : Lights when the analog audio signals are selected. DIGITAL : Lights when the digital audio signals are selected. AC-3 : Lights when a source with Dolby Digital signals is played. DTS : Lights when a source with DTS audio signals is played. 9 LOUDNESS indicator Lights when loudness is on (refer to "Front Panel" 8 LOUDNESS). 0 DIRECT indicator Lights when direct playback is on (refer to "Front Panel" = DIRECT). - Tuner indicators STEREO : Lights when an FM stereo broadcast is received in the auto stereo mode. TUNED : Lights when a broadcast is received. MONO : Lights when the tuner is set to receive FM broadcasts in monaural. 2 Digital indicators dts : Lights when DTS signals are input. ( /DTS mode is ON) PRO LOGIC : When the Dolby mode on the reciever is on, this indicator lights during 2 channel playback of Dolby Digital sources. DIGITAL : When the Dolby mode on the reciever is on, this indicator lights to indicate playback of a Dolby Digital signal. However, PRO LOGIC lights during 2 channel playback of Dolby Digital. = H. P indicator Lights when headphones are plugged in. ~ Speaker indicators Light to indicate the current speaker system (refer to "Front Panel" 7 SPEAKERS (A/B)). SP 3 A : Lights when speaker system A is selected. SP 3 B : Lights when speaker system B is selected. 3 SFC (DSP) mode indicator Lights when the DSP mode or ADVANCED THEATER mode (exept for 5-D THEATER) is selected. !
