4. If you wish to cancel the security code function, then repeat steps 1, 2, and 3 and
press PB1 four times as your new security code (security code function disabled).

distributor for further assistance.
4.1.5
I-CHIP
The I-CHIP functions in a way that is very similar to a SIM card inside a mobile phone,
which stores system information such as your telephone number, account number,
phone book and other settings. The I-CHIP works exactly the same way, as it stores
information such as system serial number/ID code, channel configurations and
pushbutton configurations.
Refer to the I-CHIP PROCEDURE within the Enrange Flex EM/EX/Pro Transmitter
ATEX/IECEx Information sheet (198-80210-0010).
For a complete information transfer, make sure both the Channel and Function
dipswitches are set to all “1”. If both dipswitches are set to all “1”, then the transmitter
will operate according to the pushbutton configurations and channel stored inside the I-
CHIP. If both the Channel and Function dipswitches are set to values other than all “1”,
then the transmitter will operate according to the channel and pushbutton configurations
set on these two dipswitches rather than the ones stored inside the I-CHIP. Every time
the settings on these two dipswitches are changed, the new settings will be stored into
the I-CHIP automatically. In this case the previous channel and pushbutton
configurations stored inside the I-CHIP will be erased and will be replaced by the new
settings.
For safety purposes, the system serial number/ID code stored inside the I-CHIP cannot
be changed directly on the transmitter encoder board. Only channels and pushbutton
configurations can be changed directly on the encoder board via Channel and Function
dipswitches. There are only two ways that you can change a transmitter serial number/
ID code:
1. via the I-CHIP programming port located on the decoder module inside the receiver
unit (
see Section 4.2.6 on page 45
on how to program the I-CHIP [serial number/ID
code] via receiver unit)
2. via an external I-CHIP programmer or duplicator unit available from the factory.
Please ask your local dealers for assistance if your system requires serial number/ID
code adjustments.
