GXE502X User Manual 7/9/2008
-Firmware Upgrade
The Firmware Upgrade sub menu allows users to upload new firmware versions to the GXE502X and upload custom voice prompts.
Please read the release notes carefully prior to upgrading your firmware to document the changes. Grandstream also recommends saving a backup file of all GXE502X configurations (please see the next section). The firmware upgrade will not overwrite your existing GXE502X configuration, but it is good practice to keep a backup copy in case.
Once you have downloaded and uncompressed your new firmware, click the Browse… button to find and select the “gxe50xxfw” file on your computer. This file is located in the “image” directory of the firmware package. After the file has been selected, click the Submit button and wait for the file to finish uploading. When finished, reboot the GXE502X to load the new firmware.
Custom voice prompts may also be uploaded in the Firmware Upgrade sub menu. To upload your custom prompts browse to the prompt file in the System Prompt Image field and click the Submit button. You can upload zip files containing .wav files or a PV files that have been generated by the Grandstream Wavtools.exe prompt generator.
