When the 760 Expansion Battery is not activated when connected to the 767 Power Station for the first time, please try the following tips:

• The first step is to connect the cable of the 760 expansion battery to the 767 power station following normal steps. It is also possible that the connection may fail during the process. If it does, the cable must be disconnected and reconnected to connect the 760 expansion battery with the 767 Powerstation successfully. 
• If the connection still needs to be successful, then should disconnect the host (power station A1780) from the power source. The next step is to repeat the above process and then connect the inactive power station to the AC input or DC input for recharging.  After the successful connection, there should be an icon for the expansion battery in the LED of Powerstation 767.
