6. Gain Access to SIM Card and Battery
To change SIM card or battery in a Chatter unit, you must gain access to the
unit’s circuit board.
6.1 Pipe Mounting
1. Open and remove the padlock that prevents unauthorized access to the
Chatter unit.
2. Turn the green top approx. 1 cm counterclockwise (but do not lift it off!)
3. Leave the top on for about two minutes and then lift it off.
This is to ensure a valid measurement and to allow time for sending an
alarm to the server.
4. Remove the pressure transmitter connector by turning the union counter-
clockwise.
5. Dismount the cover plate by removing the seven screws that secures it:
