Note before testing：
Testing Voltage 13.8V
Pay attention to have correct setup for testing machine.
Do not change inside or parameter at will.
Before assemble the cover, delete the factory mode by the factory software.
Do remember to reset radio to factory default after assemble the radio.

Frequency point for testing：
Band A
Channel 1：RX(24.025) 、TX(24.105)、NB/ANL open
Channel 2：RX(27.065) 、TX(27.100) 、NB/ANL open
Channel 3：RX(30.105) 、TX(30.095) 、NB/ANL open

New radio reset：All new radio will auto reset after power on, but required to manual reset again: Hold FUNC＋SCAC＋
COLOR key and power on the radio，LCD show “REST ALL” then show ”REST END” , the full reset is done.
Note：Hold FUNC to power is half reset, the LCD show RESET.
Check Quiescent Current Turn off SQ
，
In AM/FM/USB/LSB, all < 400mA
（
LCD color is RGB
）
Check Display： Hold SCAN to power on，to check 2 LCD.
Check Backlight LED：
A、Power on and repeat press COLOR key，the LED show ：RED、GREEN、BLUE 3 colors，make sure the LED work fine
before install LCD board.
B、Switch to DIM position ，The big LCD show DIM：31，adjust channel knob until big LCD show DIM：OFF，check the changes
of darkles, the smaller data get darker backlight.
Check voltage： In function menu, the “LCD：ｘｘｘ” Set to N＆DC，the big LCD show voltage. The voltage shall be ±
0.10Vcomapred with the supplied voltage, adjust the R521 560K resistance if not match.
Check keys and buttons： check the function, look and touch of full panel, key, switch, Knobs.
Check programming：
Program the radio with Frequency point listed in top of this instruction, cancel the factory mode by the factory software.
VCO voltage： Testing TP510 and TP509，
TP510：between 1.0-4.0 in all frequency band，no Fluctuation，if not match, adjust C801 8P capacitance，Capacitance
toleration is ±2P，check other problem if it not match.
TP509：between 0.8-5.5 in all frequency band，no Fluctuation，if not match, adjust C555 4P5 capacitance，Capacitance
toleration is ±2P，check other problem if it not match.
Note：2 VCO are connected, when TP510 testing un lock，TP509 also unlock，only when TP510 locked，TP509 can be locked
