P360 Physical address number (CD-CH) "Diagnosis data source" The detailed items depend on the data source. Ex. SyS The data was obtained from system check. "Logical address" The logical address number for the device with failure is displayed. Ex. 1L_63 Logical address number (CD-CH) The logical address is displayed. Serial number "Diagnosis code" The diagnosis code indicates what problem occurs. Ex. 1d_45 Diagnosis code (abnormal EJECT) The diagnosis code is displayed. If there are two or more diagnosis codes, the diagnosis data display will continue. Ex. COdE The data was obtained from diagnosis memory data. "Logical address"...The same as that for the SyS data "Diagnosis code"...The same as that for the SyS data "Sub code"...This code indicates the device with failure. Ex. 1P_190 The sub code is displayed. "Connecting confirmation number (when some failure occurs)"... AVC-LAN time stamp Ex. no01 The connecting confirmation number (expressed in the hexadecimal number system by using 00 to FF) The connecting confirmation number is displayed. "Frequency of occurrence" ...The frequency of failures occurred Ex. 1c_15 The frequency of occurrence expressed in the decimal number system.

Volume Control To increase the volume, turn knob to the right. To decrease the volume, turn it to the left. Lights up when an FM stereo broadcast is being received Lights up during SCAN or Preset Scan Band Preset number Frequency AM/FM1Æ2 If you press the AM button, power to the ra- dio switches on and an AM broadcast is re- ceived. If you press the FM1·2 button, power to the radio switches on. Each time you press the button, the setting changes as below. FM1 FM2 1 2 6 3 5 47 1 2 Automatic Tuning Broadcast stations above a certain signal strength can be tuned into automatically. To cancel, press the button again. Press the button down either on the “ ” side or the “ ” side. The automatic tuning will start, and the radio will find and tune into the sta- tion. Manual Tuning This is useful to tune into a station with a weak signal that cannot be found with the automatic tuning. Turn the knob clockwise or counterclockwise until you find the frequency you want. Preset Memory This function is used to memorize radio sta- tions. To memorize a station: Choose one button and press it down for about 1.7 seconds until you hear a beep. To select a memorized station: Having memorized a station, you can press the same button again and within 1.7 sec- onds the radio will tune into that memorized station. AM Tuning Step The tuning step employed in the radio’s AM band can be switched between 9 kHz and 10 kHz per step. Reset the tuning step from 9 kHz (the factory preset step) to 10 kHz when you want to receive a 10 kHz step broadcast station (530 – 1,710 kHz) in Vietnam. Initial setting: 9 kHz step (531 – 1,602 kHz) New setting: 10 kHz step (530 – 1,710 kHz) 1. Push the power button to turn the unit off. 2. Simultaneously press buttons 2 and 5 of more than 1.7 seconds. The current AM tuning step is indicated in the display. 3. Press the “ ” or “ ” side of to select the tuning step. 4. Simultaneously press buttons 2 and 5 of . A beep sounds to inform you that the tun- ing step has changed and preset memory will be cleared. Preset Scan The radio will automatically tune in to all of your preset stations which are of a certain signal strength one by one for about 10 sec- onds each. Keep the button pressed for more than 1.7 seconds, until you hear a beep. To cancel the preset scan, press the button again. • If you choose Preset Scan on the FM waveband, it will be automatically carried out on both FM1 and FM2. • Preset Scan is for reception of strong broad- cast station transmissions only. You can- not use it for reception of weak broadcast station transmissions. Scan The radio will automatically tune in to stations which are of a certain signal strength in turn for about 10 seconds each. Press the button quickly (for less than 1.7 seconds). To cancel the scan, press the but- ton again. Mode This selects the volume and tone adjustment modes. Press the knob to change the mode. After selecting the mode, adjust using this knob.
