EL-Skyport Receiver Universal, dead or alive?

• Connect to the charger and wait a few minutes.
• An irregular flashing green light (it can be a very weak light) should appear.
• If you see the green light, please find the small hole above the on/off switch and press for about 10 seconds until the green light gets stronger. This will reset the module and the deeply discharged battery. Note: the charger must be connected during this process.
• The Universal Module’s battery should recover. If not, please contact your Elinchrom service center.
