• Conventional batteries must not be recharged. They might explode!
• If the device is not used for a longer period of time (when stored, for example), remove the
inserted batteries/rechargeable batteries to prevent them from leaking and causing dam-
age.
6. Inserting/replacing batteries
• Slide down and remove the wall holder on the back of the heating control.
• To open the battery compartment slide down and remove its cover (see the arrow imprinted
on the cover).
• Insert two high-quality alkaline Mignon/AA batteries; ensure correct polarity. You will find
corresponding figures in the battery compartment.
Make sure that you insert the batteries correctly to avoid damaging the heating
control’s electronic components.
• Close the battery compartment again.
Although you can use rechargeable batteries to operate the heating control, both
the battery life and the range will be reduced. If you experience any problems whilst
operating the heating control with rechargeable batteries, use conventional alkaline
batteries, as described above.
• The heating control performs a short display test, after which you can set the date and the
time. See section 9, page 15.
• If the battery icon (‘ ’) appears, the batteries are used up and should be changed as soon
as possible. The same applies if the radio range decreases or if data are no longer displayed
on the LC display.
