The current temperature setting will be displayed for a
moment, then the 100’s digit will begin flashing,
indicating that the station is now in the temperature
setting mode. Proceed with the procedure on page
4&5.

2. If 

 is pressed for less than one second, the present

temperature setting will be displayed for two seconds,
then the display will again show the tip temperature.

1. After setting the temperature, remove the card. The

preset temperature cannot be changed until the card
is reinserted, even if the power switch is turned off.
Thus, the power can be turned off and on without
having to reset the temperature each time, and
accurate and safe temperature control is assured.

2. Any HAKKO 937 card can be used with any HAKKO

937 station.

3. The HAKKO 937 will operate normally with a card inserted.

If the power is turned off while the card is inserted, when
the power is turned on again, the previously set
temperature will be used to heat up the soldering iron.

For greater convenience and soldering efficiency, two
stations can be securely stacked.

NOTE:

If the power switch is turned off during any step of the
temperature adjustment procedure, the setting will not be
stored in memory.
