 Note: We recommend replacing the battery pack after 4 years of operation.
1. Caution: Electrolyte inside. Risk of health hazards associated with electrolyte leakage.
Do not disassemble, puncture, modify, drop, throw, or cause other unnecessary shocks
to batteries.
2. Caution: High current if shorted. Risk of injury by high current. Do not short circuit the
batteries.
3. Caution: The batteries might be hot. Risk of burns by hot surface. Do not touch the
batteries before they have sufficiently cooled down.
Notice: For the replacement procedure, also observe the health and safety warnings
in chapters 5.1 and 5.2.1 as well as the notes in chapter 5.2.
Do not put the batteries to the garbage but dispose of them properly according local
and/or regional regulations.
To replace the battery pack, first uninstall the multiband combiner as explained in
chapter 5.2.1. Then, proceed as follows:
 Unplug the complete module on which the battery pack is installed. Disconnect the
battery cable at the UI2 board.
 Just loosen the M3x16 hexagon socket-head-cap screw on top of the cover of the
battery pack. It is not necessary to unscrew this screw entirely!
 Then the battery pack can be removed easily.
 Insert the new battery pack and fasten the M3x16 hexagon socket-head-cap screw
again.
 Reconnect the DC connector to the "Battery" connector at the UI2 board.
