B. The preset mode
The HAKKO FR-702 (Soldering iron) has a preset mode that will allow the unit to store up to 5 preset
temperatures you can change between instead of using the above normal mode.
Initial preset temperatures
P1: 250℃ (482℉), P2: 300℃ (572℉), P3: 350℃ (662℉), P4: 400℃ (752℉), P5: 450℃ (842℉)
The initial number of active presets is set to 5 at the factory.
The default selected preset is set to P3 at the factory.
Example : Changing preset temperature from preset No.1(250℃) to No.3(350℃).
Heater control will begin with new preset temperature.
The procedure for making changes to the preset temperatures is the same with “A. Changing the set
temperature” in 5. OPERATION (Soldering iron).

C. Performing the temperature adjustment
When replacing the iron, heater or tip, a temperature adjustment may be required.
Use adjustment mode to perform the temperature adjustment.
• Enter the observed value in the adjustment mode after the tip temperature stabilizes.
• The maximum single adjustment that can be made is ±150℃ (270℉) relative to the set temperature.
If a larger adjustment is needed, make the first adjustment at the maximum value of 150℃ (270℉),
then repeat the adjustment process.
• When a new soldering iron is used or insertion position is changed from A.IRON to B.IRON (and vice
versa), temperature adjustment is always required.
NOTE :
During adjustment mode, the hundreds digit will accept
values from 0 through 6 if the temperature is set to display
in ℃, or the values 0 through 9 if the temperature is set to
display in ℉.
