3G to 4G Modem Replacement Instructions
- Disconnect the controller from the power supply:
- AC – Disconnect from socket.
- DC – Disconnect the battery from the PCB (Figure 1).
- Open the GSI controller and press the RESET button for 10 seconds (this causes a complete discharge of the power left in the panel).
- Remove the two screws and gently disconnect the old modem. The antenna connected to the modem should be gently disconnected from it.
- Connect the antenna to the new modem. Place the new modem on the board and tight the screws back.
- Turn the power back:
- AC – Connect back to the power supply and wait until a view is obtained on the controller.
- DC – Reconnect the battery on the board and wait until a view is obtained on the controller.
- Wait up to 3-7 minutes for the modem to detect communication and display the current time.
- If the controller has not made communication, try pressing RESET again.
Care must be taken to disconnect the power and discharge the capacitors
(sections 1 + 2) to prevent irreversible damage to the
modem.
