Some effects will behave differently after the update, and this may result in unexpected changes in programmed presets and cues.
We recommend that you do not update fixtures while they are part of a running show or tour setup. If the fixture refuses to accept the new firmware, contact your nearest Martin Service Partner. If the fixture becomes unresponsive, leave it with power applied for approximately 15 min before powering off and on and then trying the upload again. Do not switch off the fixture or disconnect it from AC mains power during the upload. Once firmware v is installed, the fixture will no longer accept an upload of any earlier firmware version. 1 MAC Viper Series Firmware v Upload Instructions This guide explains how to update your MAC Viper Series with firmware version Important A USB flash drive is required for this update.
