click "write Flash"
wait until the progress bar reaches 100%. If it doesn't go through, click "Write Flash"
again until it does complete.

revert to factory defaults.

Maintenance
Please wash the modem with warm water (only) to remove any built-up which could negatively
affect its operation. Apply a thin film of silicone grease to the rubber part of the connector pins
to protect the connector and to facilitate mating. For maintenance details regarding the
connector follow SeaConn's instructions.
