Picomed ER2AC and ER4AC receivers for InfraRed (IR) light receives IR light emitted from
IR-transmitters. To receive these signals it is an advantage that the receiver not is covered by
anything which can block the emitted signal from the transmitter. Usually the IR-signals will
be reflected by floor, walls and roof, so in most cases there is no need to point directly against
the receiver with the IR-transmitter. The distance between the receiver and the transmitter
should be more than 1 metres to make the most of this reflection effect.
The receiver will be controlled by a transmitter with the same type of IR-signals and the
correct codes.
There is no need for maintenance for the IR-receiver, and there is no batteries etc. which has
to be changed. If the IR-receiver needs to be cleaned, it can be cleaned with a humid cloth,
alternatively use a mild soap.
There is a red light indicator in the front of the IR-receivers which will lit when it receives a
known IR-signal. Keep in mind that it should not be covered by anything which can prevent
the IR-signals to reach it, and it should not be exposed for direct sunlight.

2 Technical documentation
The IR-receiver is ment to be wall-mounted in a standard box. It can also be flush mounted in
a standard box. There is no need for any dissasembling for periodical maintenance,
inspections or repairments.
2.1 Periodically maintenance
The IR-receiver is developed to work without any need for periodical maintenance. There is
no internal battery to be changed.
2.2 Mounting
Picomeds IR-receiveres ER2AC and ER4AC is ment for wall mounting. All electrical wires
shall be disconnected when mounting the receiver. It shall be mounted in a place where it not
will be covered by anything which can block the IR-signals. Even so, it is very often possible
to place it behind curtains etc, and still it will work to the users satisfaction. Direct sunlight
which shines on the receiver will very often reduce the receivers sensitivity.
