3.1 Power supply:

Advice regarding batteries:
We advise you to use alkaline batteries in the indoor unit. Alkaline batteries with a capacity of 2000mAh
have a lifespan of over one year. Rechargeable batteries are not recommended because of their lower
supply voltage.
The outdoor unit is also powered by 3 AA 1.5 Volts batteries, but we recommend not using Alkaline batteries
in the outdoor unit, because the performance of Alkaline batteries degrades at temperatures around of
below 0°C.
For that reason, we advise you to use Lithium batteries for the outdoor unit that are designed to function
well within a temperature range of -20°C to 60°C. These batteries can be ordered via the service depart-
ment of Alecto via internet: www.alecto.nl
Lithium batteries with a capacity of 2900mAh have a lifespan of over one year.
