“SET” key once to finish the temperature correction and the unit automatically 
backup mode. The user may continue set other modes or back from the current 
setting mode.     
Example for temperature correction: The current set temperature value is 300

℃,

 

however, the actual temperature is only 290

. So it needs to correct by +10

Correction method: if the current correction value is 00 or -00; then change it to 
10. If the current correction value is -20, then change it to -10. If the current 
correction value is 20, then change it to 30.

Sleep Mode Set:   

Press “SET” key one time when the LED displays “F-3” and flashes, the unit 
enters the Sleep mode status. At this moment, the LED displays the pre-set value. 
Press “▲” or “▼” key to change the set value. If set value reads “000” that 
means the unit set in “Sleep” mode releasing status. If the display read “100” that 
means the unit set in “Sleep” mode. Press “SET” key once to finish the sleep 
mode setting, then the unit automatically backup. The user may continue set 
other modes or back from current set mode.   

 

Please note the manufacturer original design will keep in “Free” status 
without setting “Sleep” mode.

Wake-up method:   

 

Temperature Down Suspend: If the unit is set at Sleep mode function, after 20min   
idleness, the system will enter the sleep mode automatically, the temperature of 
soldering will go down to 150

  (302

℉) 

/ and the LED displays at “ 150” and 

flashes

the temperature of desoldering will go down to 200

  (392

℉)

 and the 

LED displays at “ 200” and flashes

Activating the solder wand will disengage the 

suspend status and the unit will immediately ramp up to the preset temperature.   
There are three methods to wake-up the Temperature Down Suspend. 
a

.

 Soldering: Pick up the solder wand HF-90 and shake it gently. 

 

b. Press any key of the unit.   
c. Turn off the main switch and restart. 

2

  Power off Suspend: If the unit enters the Sleep mode over 40min without wake-up, 

the unit will enter automatically the power off suspend status. It means the heater 
power will be cut off and the LED displays “— — —” and flashes. You can wake 
it up by pressing “

” key when you reuse the iron or turn off the main switch and 

re-switch on.

Fahrenheit and Centigrade (Celsius) temperature selection   

When temperature display window shows "F-4" and blinking, press the "SET" 
button, at this time ,the system enters the degrees Fahrenheit and Centigrade 
temperature selection function, indicating the temperature of the window shows 
the current status.   Press "▲" or "▼" key to change the temperature selection 
status. It expressed as degrees Celsius temperature value if set to “
