* Use only the power supply supplied with the device! In case of failure, it can be replaced with a high-quality modern switched-mode power supply with an output voltage of DC 12 volts, the center is plus and an output current of at least 0.5 amperes (more is fine). The power supply must have a wide AC input voltage range of 100-240 volts. Such power supplies have excellent output voltage stabilization required for the device. It is forbidden to use COSMOS with nonstabilized voltage from transformer power supplies. It can lead to damage to the device, which is not covered by the warranty repair!
