Replacing the GM10 Module
To replace the module:
1.
Disconnect the transmitter body from the mounting base.
2. Locate the GM10 module on the transmitter. The module is a
separate component board with a golden cuvette that contains the
CARBOCAP ® sensor. The module is connected to the main
transmitter board with a connector, and held in place by a plastic
clip on the other side. See Figure 4 on page 17.
3. Disconnect the module by carefully lifting the module from the
connector side. See Figure 28 below.

connector end of the module.
5. Push down on the module to secure the connector.
6. Reconnect the transmitter to the mounting base.
7. Verify that there are no errors when the transmitter starts up. If
there are, see section Error Messages on page 73.
