# To redial the base modem

If you lose the connection to the cellular phone or modem at the base station when using a dial-in data link, tap the cellular modem icon in the status bar.

The Rover data link screen appears.

To redial the modem at the base station, tap Redial.

To end the connection at any time, tap Hang up. Continue the survey and then reconnect to the modem at the base station when required.

When you redial a VRS service provider, a new VRS base station position is sent through the data link. The Trimble Access software switches to the new base, and the survey continues.
