8.1 Battery Installation

The SRU uses one 9V replaceable alkaline or lithium battery. To install or replace the battery, remove the SRU from the protective outer case. Push up to remove the battery enclosure door from the back of the SRU. Connect the battery lead to the 9V battery and install the battery in the housing. Replace the battery enclosure door and the protective outer case of the SRU.


It is recommended to replace the battery when the level falls below 20%.
