Version 1.0:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Added Synapse Firmware update feature<\/span><\/li>\n<li style=\"font-weight: 400;\"><span

style=\"font-weight: 400;\">OPERATIONAL CHANGES<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Freefly is making available a new revision of both the Setup Guide and Aircraft Flight Manual (previously User Manual) that include the changes contained in Synapse Version 3.4.0.<\/span><\/p>\n<p><strong><strong>\u00a0<\/strong><\/strong><\/p>\n<p><span style=\"font-weight: 400;\">In particular, operators should study the Normal Procedures and the Radio Mapping sections as they contain information on the new Disarm Safety switch. This switch replaces some, but not all of the functionality of the Arm Enable switch.<\/span><\/p>\n<p><strong><strong>\u00a0<\/strong><\/strong><\/p>\n<p><span style=\"font-weight: 400;\">METHOD OF COMPLIANCE<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Synapse Version 3.4.0 is packaged in Alta App version 1.1. Download the update to your mobile device using either Android Play for Android devices, or the App Store for iOS devices.<\/span><\/p>\n<p><strong><strong>\u00a0<\/strong><\/strong><\/p>\n<p><span style=\"font-weight: 400;\">To update firmware, follow the steps in the Aircraft Flight Manual in the section Firmware Update Process.<\/span><\/p>\n<p><strong><strong>\u00a0<\/strong><\/strong><\/p>\n<p><span style=\"font-weight: 400;\">After updating, reversion to Synapse Version 3.02 is also possible with the app using the same process.<\/span><\/p>\n<p><strong><strong>\u00a0<\/strong><\/strong><\/p>\n<p><span style=\"font-weight: 400;\">KNOWN ISSUES<\/span><\/p>\n<ul>\n<li>When loading presets saved from Synapse Version 3.02 onto an Alta with Synapse Version 3.4.0. After loading the preset, the App will display a warning that some configuration settings may not have been loaded. This error will display even if all the settings were successfully loaded. Because the warning indication is unreliable in this case, it is recommended to check that all settings are correctly loaded prior to flight. Presets will load without false warnings when the same Synapse Version number is used to save and load them. For instance, if a preset saved in Synapse Version 3.4.0 is loaded onto an Alta with Synapse Version 3.4.0 without errors, an error warning will not be displayed.<\/li>\n<li>Motion Booting will toggle to ON when upgrading or reverting firmware. It is recommended to check the Motion Booting parameter after upgrading to Synapse Version 3.4.0, or reverting to Synapse 3.02.<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">For Service Information Contact:<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Freefly Customer Support<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Email: support@freeflysystems.com<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Phone: +1 (425) 485-5500<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Hours of Operation: M-F 8am-6pm PST<\/span><\/p>\n","protected":false},"template":"","class_list":["post-22458","kb_article","type-kb_article","status-publish","hentry","support_category-alta","support_category-alta-firmware-and-app-release-notes","support_tag-alta-app","support_tag-firmware-release-notes","support_tag-synapse","support_tag-ver-3-4-0"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v24.7 (Yoast SEO v26.0) -
