5.7.10.2 Battery
A replaceable battery, which is necessary for buffering date and time, is located
below the control panel on the upper board of bp408.
The replacement of the battery is only permitted in the disconnected state of the
controller. The battery can be carefully removed from the holder. In order to insert,
the new battery is pushed below the holder. While doing so, attention must be paid
to polarity. Battery replacement is now completed.
The battery is a type CR 2032 and shall only be replaced with the identical type.
NOTE!
Maintenance of the battery
The battery must be replaced every 5 years. Spare batteries can be ordered via
our service.
NOTE!
Disposal of the battery
Batteries must not be disposed of as household garbage. Used batteries must be
put in collection boxes specifically designed for that. If there is no collection box
nearby, used batteries can also be disposed of at municipal collection centres for
hazardous household wastes. Of course, you can return to us used batteries
received from us.
You can thus fulfil the legal obligations (Battery Ordinance) and contribute to
environmental protection.
Batteries that contain hazardous substances are marked with the
crossed-out dustbin symbol. The chemical name of the hazardous
substance is given under the dustbin symbol - “Cd” for Cadmium. “Pb”
stands for lead, “Hg” for mercury.
