5. Preparing for operation
5.1. Open the housing
- Rotate the unit and unscrew the 6 screws (see below)
- Lift up the upper part carefully.
5.2. Inserting the batteries
- The unit is operated with 3 x 1,5 V AA batteries. Use alkaline batteries
for longer life and better protection against leaking.
- Insert the three batteries into the battery holder with right polarity as
shown in the battery holder.
- If you want to make settings (addresses or measuring unit), go to the
next chapter.
- Finally, close the housing. Be sure the temperature sensor is placed in
the correct position in the housing and most importantly that the neopre-
ne seal ring is aligned properly before you close the housing and tighten
the screws. Tighten the screws carefully in a diagonal sequence.
