5.2. Memory Function
1. Set proper pre-curing and full-curing time according on the paint type.
2. Press and hold one of the four memory buttons for 4 seconds, the pre-curing and full-curing
time will be stored in this button. Four different settings can be stored.
3. When you need the stored setting, press the corresponding key.
4. To reset a memory button, repeat steps (1) & (2) to store new settings.
5.3. Distance Control
1. Left red indicator: Distance is too far.
2. Left yellow indicator: Distance is rather
far.
3. Green indicator: Distance is suitable.
4. Right yellow indicator: Distance rather
close.
5. Right red indicator: Distance is too close.

IR-B03 / IR-B03-T Page 10
5.4. Curing Times
The quality of the drying result highly depends on the share of pre-curing time in the total curing time.
The higher the share of pre-curing (flashlight), the better might be the drying result. Too fast drying
may lead to small pores / bubbles. As reference value a ratio of 1/3 pre-curing (flashlight) to 2/3 full-
curing (continuous) is recommended. All values are reference values. For exact values please contact
your paint supplier.
