Replacing Modems
==================

If we supply you with a replacement modem, for example to upgrade from 2G to 4G comms, please follow the procedure below:

- Ensure the meter is **fully turned off** before replacing the modem.  
- For Emlite meters, the modem is situated at the top of top of the meter and can be removed by loosening the screw(s) holding it in place.
- For Elster A1140 meters, the modem is situated under the bottom cover, which is held in place by two screws, left and right.
- Please record the following information:

1. **Serial number** of the modem, which can be found on the rear of the modem.
2. **Serial number** of the meter that you are fitting the modem on to.

Please provide the information above to the staff at support@juggle.energy who will be able to update the records in Juggle.

Installing New ASL Meters

- If this is a replacement meter, the existing "**emig ID**" of the meter.
