1
1.Removing the Case Assembly from the Chassis
(1)Remove the two screws
(2)Remove the channel knob and volume knob
(3)Remove the channel copper nut, volume copper nut, antenna
head copper nut and antenna head waterproof ring.
(4)Open the USB port cover, do not lock the USB port.
(5)Disassemble the front case and chassis, be careful not to
overexert,In order to avoid the speaker cable and cable break
(6)Remove the cable from the PCB.
(7)Use a soldering iron to remove the speaker cable from the
PCB

2.Remove the keypad from the Chassis
(1)Remove the eleven screws which connect the PCB
(2)Using a soldering iron, dissolve the tin on the antenna end,lift it
up and remove the PCB from the aluminum case at the same time.

4. Assemble the PCB to the aluminum case
（1） Put the aluminum antenna pin on the antenna board and align it
with the corresponding positioning hole on the PCB,lock the screws
into all 11 screw hole,fix PCB Board and the aluminum shell.(Note:
PCB board should be close to the aluminum shell, do not have tilted
phenomenon, the screws should be fully and intact locked.)
（2） Solder the antenna head with a soldering iron.(Note: Tin point
must be full, smoothly, no brushed)
