TK-521010DISASSEMBLY FOR REPAIR7. Insert the VOL/CH FPC 8 and the CONTROL-TOP FPC 9into the connectors (CN902, CN903) of the TOP PCB.8. Fix the TOP PCB with a screw 0.9. Fix the TOP PCB with a screw !.■ TX-RX PCB Installation Procedure1. Insert the coaxial cable of the antenna receptacle into thecoaxial connector (CN101) of the TX-RX PCB 1 and thecoaxial cable of the ANT PCB into the coaxial connector(CN102) of the TX-RX PCB 2.2. Grasp both sides of the lower part of the TX-RX PCB, tiltthe TX-RX PCB and install the chassis so that the PTT FPC3, CONTROL-TOP FPC 4 and universal connector FPC5 are not caught 6.3. Fix the TX-RX PCB with the 14 screws.■ LCD ASSY Installation Procedure (K2 and K3models only)1. Remove the two adhesive sheets attached to theCONTROL PCB, and attach the new adhesive sheets tothe location as shown in the following figure.2. Fold the LCD ASSY FPC to the back of the holder 1 sothat the FPC is between the two tabs on the right side ofthe holder 2.3. Fit the two tabs on the right side of the holder 3 and thetwo tabs on the left side of the holder 4 into theCONTROL PCB.Note:Take care that the FPC is not caught when fitting the twotabs on the right side of the holder.4. Insert the FPC into the CONTROL PCB connector (CN751)5.■ Main Packing (G53-1637-04) Installation Procedure1. Hook the packing (coated with silicon oil) in the uppergroove of the chassis 1, then fit the packing into thelower groove of the chassis 2.Note:Ensure that the chassis grooves and packing are free fromdirt and dust.2. Fit the packing into the grooves on both sides of thechassis 3. (Fit the packing into the groove in the chassisby tracing it lightly with your fingers.)Note:To remove the packing from the chassis groove, use aresin adjustment bar or other such device. If the packingis pried with a sharp metallic tool, such as tweezers, thepacking may become damaged.3. Verify that the packing fits snuggly into the groove of thechassis.CN902CN90310 1189CN102CN1013 12465Grasp both sides of the lower partof the TX-RX PCB21 LCD ASSY FPCtabtabCN75151233Main packing4433tabCONTROL PCBAdhesive sheet(J99-0394-04)Adhesive sheet(J99-0393-04)CONTROL PCB
