The ingress of liquids (e.g. cleaning agents during window cleaning) can
damage the DuoFern Sun Sensor.
• Remove the DuoFern Sun Sensor from the window before cleaning the window.
• The vibration function is activated when removing it from the window and when
installing it at a later stage.
4. Changing / inserting the battery
The use of rechargeable batteries or incorrect batteries can damage the device.
• Only use leak-proof 1.5 V AA (LR6) batteries.
• If a battery has leaked, we recommend replacing the DuoFern Radiator Actuator 2
with a new device.
• Pay attention to the correct polarity when inserting the battery.
• An optimum battery life is only achieved by using a 9 V lithium monobloc battery
with the DuoFern Smoke Alarm. Alkaline monobloc batteries do not suffice.
• Only use type CR2032 batteries for the window / door contact.
For devices containing one or more button/coin-cell batteries, the following
safety instructions must be observed:
If the coin-cell battery is swallowed, it can cause severe internal burns and
death within just 2 hours.
• Children must not replace batteries.
• Do not swallow the battery, risk of acid burns.
• Store new and used batteries out of the reach of children. If the battery compart-
ment does not close securely, stop using the product and keep it away from children.
If you believe that batteries may have been swallowed or made their way into any
part of the body, seek medical advice immediately.
