Replacing Batteries; Behaviour After Replacing Batteries - HomeMatic HM-RC-4-2 Bedienungsanleitung

• This will open the catch; you can then swing open
the battery compartment
cover. The cover will stay
connected to the housing.
• Place an LR03/AAA/micro
battery into the battery compartment, using the po-
larity markings to ensure the polarity is correct.
• Close the battery compartment by swinging the
battery compartment cover back on. Push the co-
ver towards the centre of the housing (applying a
little pressure) until it latches into place.

6.1.2 Replacing batteries

If you press a button on the wireless remote control and
the flashing code indicating empty batteries is displayed
(5 x red flashes), or the device being controlled does not
respond, replace the used battery with a new LR03/AAA/
micro battery, as described in the previous section. You
must observe the correct battery polarity.
Never recharge standard batteries. Do not
throw the batteries into a fire. Do not short-cir-
cuit batteries. Doing so will present a risk of ex-
plosion!

Instructions for disposal:
Used batteries should not be disposed
of with regular domestic waste! Instead,
take them to your local battery disposal
point.

6.1.3 Behaviour after replacing batteries

Once the battery has been inserted, the wireless
remote control will first perform a self-test/restart (ap-
prox. 2 seconds). The LED will flash red, orange and
green briefly (LED test display). Initialisation will then
be carried out.
If the battery voltage is low, the button query
will still be activated and the wireless remote
control made ready for operation, provided that
the voltage value permits it. Depending on the
particular load, it may be possible to send
transmissions again repeatedly, once the batte-
ry has been allowed a brief recovery period.
If you are using weak batteries, the device may
perform a restart automatically when you press
a button. The device LED will then briefly flash
red, green and orange, and follow this with 5
brief red flashes to indicate that the battery is
weak.
