3.4 Removing / fitting the SIM card (GSM and HSDPA (3G) models)
Important! Ensure the iRIS is depowered before attempting to remove or fit the SIM card.
Exercise care when inserting or removing the SIM card, as the carrier is fragile.
Open the front cover as described above.
Using a fingernail or small screwdriver inserted into one of the two oval holes on the sliding holder, gently
lower the slide downwards to unlock it. The slide can now be swung forwards from its top end to enable the
SIM card to be inserted or removed. Reverse the procedure to close and lock the card into place.

3.5 I/O Connector
All I/O and power supply terminations are via 5mm (0.2”) pitch screw terminals provided on a 16-way
pluggable connector. The I/O connector is positioned on the right hand side of the iRIS circuit board, directly
above the white battery connector.
The function of each I/O termination is shown in the diagram below.
In the case of the iRIS 350 the designators shown in parentheses () and bold are the iRIS 320
emulation mode functions described in Section 3.5.5.
