WWAN Radio Power Management (MC9062/MC9063 Only)
The radio’s power state is not dependent on the mobile computer’s power state. In addition to its own
power state, the radio has automatic internal power management to preserve battery life when the
radio is on and not in use.
The default out-of-box radio state, upon the first cold boot of the mobile computer, is radio power on.
In its default state, the radio can remain on during a suspend and resume of the mobile computer. To
change the default radio state, use registry keys to configure on/off power during a suspend and
resume of the mobile computer.
The radio can also be turned on and off using the
Radio Power Settings
window (see
) and
the
Power
tab (see
).
The
flight mode
feature of
Microsoft® Windows® Mobile 2003 Software for
Pocket PCs Phone Edition can be "non-intuitive" when controlling the power
state of the WWAN radio. It is recommended that the
Radio Power Settings
window be used to control the GSM, 802.11b/Spectrum24 and Bluetooth
radio power. See
for more information.
