Introduction
IR-3SP Micro Jack is a programmable IR transmitter, which can learn three
different channels from another remote control for TV, VCR, stereo etc. It has
two outlets for connection of two external control switches. IR-3SP Micro Jack
is a part of the Gewa ”Smart House” concept and can therefore be used together
with the complete range.
General information about IR-3SP Micro Jack
Before using the IR-3SP there are certain things you should know.
•On delivery the Gewa Link channels (channels 16, 17, 18) are factory
programmed, this means that it is possible to use the transmitter as soon as a
battery has been inserted. See section ”Inserting the Battery”.
•For programming press the programming button, (using a pen tip or other
narrow object) at the same time as you press a function key.
•If you press the wrong key or make a mistake during programming, you can
press the programming button Pto reset.
•It is important not to wait too long between the different steps in the
programming mode. After a certain time the IR-3SP automatically leaves the
programming state to save power.
•3.0 as a superscript indicates the IR-3SP version.

Inserting batteries
Unscrew the screws holding the bottom of the IR-3SP using a Phillips
screwdriver. Remove the bottom and insert three 1.5V silver oxide batteries type
SR44. Insert the batteries according to the markings on the bottom of the battery
compartment. Be sure to observe the polarity! It is important to use specified
batteries for maximum transmission range. When you have inserted the new
batteries, press the programming button on the underside.

Replicating Channels from another Transmitter
The IR-3SP can learn three different channels, one channel for the built-in
function key and two channels for the external control switches.
Do as follows to program the new channels:
1. Make sure the batteries in both transmitters have full capacity. Do not expose
the transmitters to direct light (e.g. sunlight) during programming.
2. Press the programming button and the function button
(A) at the same time on IR-3SP. IR-3SP is now in
programming position.
3. Place the original transmitter facing the front of IR-3SP
(fig 3).
To check that the transmitters are in the right position,
keep any key pressed on the original transmitter and
move the original transmitter to the left and right until
the indicator lamp goes out. Then move the original
transmitter backwards until the indicator lamp goes out
(one metre for some transmitters). Place the original
transmitter at the centre of these maximum range
positions. Certain types of transmitters only emit a short
flash each time the key is pressed. In these cases, press
several times.
4. Press and release the function key/control switch on the
IR-3SP, which is to be programmed. The indicator lamp
now emits a steady red light.
5. Choose a key on the original transmitter and press it and
keep it pressed, this programmes the signal into the IR-
3SP. Release the key when the indicator lamp goes out. It might take up to 10
seconds. If the indicator lamp turns red again then press the key again until it
goes out.
6. Now test the programmed functions on the target device.

3.0 Tip! IR-3SP can record codes from most IR transmitters on the market with a
few exceptions. You may have problems with a few or all of the functions for a
certain IR transmitter. In these cases it is possible to use another recording
method. Instead, do as follows in step 2; Press the programming button and the
function button (A) at the same time but keep them pressed for approximately 2
seconds. IR-3SP is now in another recording mode. Otherwise use the same
recording procedure.
Mounting
IR-3SP can be used hanging on a strap around the neck. Remove the string lock
from the neck strap and pass the neck strap through the attachment loop on the
transmitter. Replace the string lock and adjust the length of the neck strap.
Warning!
The string lock is a safety detail for the prevention of strangling. Check that the
neck strap ends can easily be drawn out if the transmitter gets caught on
something. Never make knots on the neck strap!
IR-3SP can also be equipped with clips (article number 401130) which make it
possible to attach it to a belt or pocket. Clips can be obtained from Gewa AB or
a Gewa retailer.

wring out thoroughly and wipe.
Where to use Gewa IR-3SP
IR-3SP is designed for indoor and outdoor environments. Whilst it will
withstand the effect of light shower it is not waterproof and should be kept as
dry as possible. If IR-3SP gets wet it should not be used until it has dried out
thoroughly.
