14、 Specifications and features are subject to change without notice. RadioFans.CN 收音机爱 好者资料库 TX-NR900/E SERVICE PROCEDURES 1. Replacing the fuses This symbol located near the fuses indicates that the fuse used is fast operating type. For continued protection against fire hazard, replace with same type

15、 fuse. For fuse rating refer to the marking adjacent to the symbol. Ce symbole indique que le fusible utlise est a rapide. Pour une protection permanente, nuntiliser que fusibles de meme type. Ce darnier est la qu le present symbol est appse. CIRCUIT NO. PART NO. DESCRIPTION 2. To initialize the uni

16、t This device employs a microprocessor to perform various functions and operations. If interference generated by an external power supply, radio wave, or other electrical source results in accident which causes the specified operations and functions to operate abnormally. To perform a result, please

17、 follow the procedure below. 1.Press the STANDBY ON button to turn on the unit. 2.Press and hold down the VIDEO 1 button, then press the STANDBY/ON button. 3.After CLEAR is displayed, the preset memory and each mode stored in the memory, such as surround, are initialized and will return to the facto

18、ry setting. 4.Unplug the power supply cord. 3. Safety-check out (Only U.S.A. model) After correcting the original service problem, perform the following safety check before releasing the set to the customer. Connect the insulating-resistance tester between the plug of power supply cord and screw on

19、the back panel. Specifications: 3.3Mohm+/-10% at 500V. 4. Memory Preservation This unit does not require memory preservation batteries. A built-in memory power back-up system preserves the contents of the memory during power failures and even when the unit is unplugged. The unit must be plugged in o

20、rder to charge the back-up system. The memory preservation period after the unit has been unplugged varies depending on climate and placement of the unit. On the average, memory contents are protected over a period of a few weeks after the last time the unit has been unplugged. This period is shorte

21、r when the unit is exposed to a highly humid climate. Advanced Menu 0.Hardware Setup 0-4.AM Frequency Step a.Frequency Step :9 kHz 6. AM Frequency Step Sub-menu (Worldwide model only) This sub-menu only appears on the worldwide model. The setting in this sub-menu determines the increment amount or d

22、ecrement amount when adjusting the AM tuner frequency. The initial setting is 9 kHz, and this needs only to be changed if you are using the TX-NR900 in a 10-kHz region. 5.Setting the voltage selector (Worldwide models only) Worldwide models are equipped with a voltage selector so that you supplies.

23、Be can set your TX-NR900 to conform with local power sure to set this switch to match the voltage of your area before plugging in the unit. Determine the proper voltage for your area: 220-230 V or the preset voltage is not correct for your area, into the groove in the switch and slide (220-230 V), w

24、hichever is appropriate. Note: : 120V model only : Except 120V model : Worldwide model only : Chinese model only the power supply in 120 V. If insert a screwdriver the switch all the way to the top (120 V) or bottom 7. To confirm the version of microprocessor 1.Press the STANDBY ON button to turn on

25、 the unit. 2.Press and hold down the DISPLAY button after more than 15 sec., then press the STANDBY/ON button. 3.After the versions of main,sub and net microprocessors are displayed on FL tube, the unit returns to the original position.
