The Liebherr safety package with audible alarm and FrostControl display ensures ideal protection for the valuable frozen food. The turn-off audible alarm sounds as soon as the temperature in the freezer rises. The FrostControl display helps to assess the quality and further storage life of the frozen food after a power failure. The child-proofing feature protects against the appliance being inadvertently switched on or off.  The cold storage accumulators in the freezer compartment provide an additional reserve.
