The model and product number of the Spectrum Compact can be found on the sticker on the back of the unit or in the device menu ABOUT (turn the device on, tap 
button TOOLS & SETTINGS and then tap button ABOUT).

1. Turn Spectrum Compact on.
2. From the main screen tap TOOLS & SETTINGS, then tap SERVICE MENU. Tap USB MODE. 
3. If the USB mode is already set to MASS STORAGE DEVICE, do nothing. If the USB mode is set to VIRTUAL COM PORT, set it to MASS STORAGE DEVICE by tapping OK.
4. Connect the device to a computer.
5. Copy both – the firmware file (with extension “.fw”) and the initialization file (with extension “.ini”) from the "Spectrum Compact 16-26.5, 24-40_43 GHz FW" folder.
6. Open the Spectrum Compact drive and paste the two files into the FIRMWARE folder.
7. Turn Spectrum Compact off and back on. The text “FIRMWARE UPGRADE” should be shown.
