 Date and Time: page to modify real time clock. When the Signal Booster is not
powered, this clock runs with a voltage supply provided by a 3V lithium battery,
button type of 20mm (CR2032) with 220mA·h. This suffices for at least half year.
When the Signal Booster is powered, no current is drained from the battery. So,
actual battery life will depend on Signal Booster usage. For battery replacement,
please locate battery holder between USB and Ethernet connectors on main board.
Battery positive side is UP, i.e. on holder clip.
After clicking on “Apply Changes” link, next message will appear, warning the user that
system needs to be rebooted.
