Power save mode

Simply said what does the power saving mode do. Enabled or disabled?

According to the Release Notes for 8.2.4 on page 10 it states:

P10 modules now offer a “Power Saver Mode” on the
Configuration => Radio page. “Power Saver Mode” uses
improved power management to reduce power consumption
by about 1 W (10%), depending on module settings and traffic.

The recommended setting is “enabled”, which is the default.

Note, this feature reduces power consumption, but does not
affect transmitter output power, which remains at the value set
by the “Transmitter Output Power” parameter on the
Configuration => Radio page of a module.
