Those units may display diagonal interference lines on the picture mainly in VHF bands. Note that the braid of the good quality cable is very tight and totally covers the internal wire. Instructions Replaced the faulty RF cable assembly using the part number 40252200111. Regards, Alcides Berta TEAC Australia Pty Ltd. RadioFans.CN 收音机爱 好者资料库 TECHNICAL BULLETIN 12-July-2000 Page 1 of 1 MODEL: CT-F683, CT-M6828S, CT-M5930 PROBLEM: I2C Mitsubishi chassis. Service Mode adjustments File: CT-F683 CT-M6828 5930 RC tb.doc The following information applies to all Great Wall models using I2C Mitsubishi technology. A special type of remote control is necessary to access Service Mode adjustments, please refer to the figure. Accessing Service Mode 1- Press first button on the left of the FACTORY ON row (Button 1). The word Key is visible on the screen. 2- Press FACTORY button (Button 2). The first page of factory adjustments will be displayed. 3- Navigate between parameters and different pages using UP and DOWN buttons. Direct access to frequently used parameters is available from dedicated buttons, for example EW WIDTH, V AMPL, etc. 4- Adjust parameter values using VALUE+ and VALUE -. Leaving Service Mode 1- Press first button on the left of the FACTORY ON row (Button 1). The work Key is visible on the screen. 2- Press STANDBY button. 3- Turn POWER off from the front panel switch for at least 15 seconds.

TECHNICAL BULLETIN 21-Jul-2000 Page 1 of 1 MODEL: CT-M6828S CT-F683 CT-M5930S PROBLEM: Audio noise File: CT M6828S M5930S F683 noise tb.doc A humming noise is audible at low volume from the speakers and particularly from the headphone output (when available). The source of this noise is the vertical deflection circuit. Instructions 1- Delete the jumper W286 on the main PCB next to CN111 in the fly-back transformer area. 2- Add a cable between the IF shielding can and the heat sink for the audio output IC. Regards, Alcides Berta TEAC Australia Pty Ltd. TECHNICAL BULLETIN 11-August-2000 Page 1 of 1 MODEL: CT-M6828S, CT-M5930 and CT-F683 PROBLEM: Incorrect resistor type File: CT-M6828S m oxide.doc An incorrect resistor type has been fitted in position R504 of the neck board in some units. A carbon film resistor having a light brown color body and mounted on the surface of the PCB can eventually ignite and burn the board. Instructions Replace the carbon film resistor in location R504 with a metal oxide type. Separate the new resistor from the surface of the PCB by approximately 10 mm.
