1) Enhanced User Interface
a. The user interface of the original software was based on a four line text display.
All text was of the same size. The enhanced user interface makes better use of
the display by using different character sizes for different levels of information,
and simple graphical elements such as lines and icons to aid legibility of the
display.
b. The original user interface employed a simple hierarchy of menus which were
intuitive and simple to navigate. The enhanced user interface builds on this,
retaining the same hierarchical structure while providing additional information
to aid the user.
c. The time display in Standby mode is much clearer, and also provides alarm
status indicators.
2) Backlight and Contrast adjustment
a. The original user interface always ran the display backlight at full intensity
except when running the radio on batteries. The enhanced user interface allows
the display brightness to be adjusted to four levels - Off, Dim, Mid and High. The
level may be set independently for when the radio is in use and when it is in
standby.
b. If the backlight is set to Off when the radio is in standby, then pressing a button
will cause the backlight to brighten up to the active setting for a few seconds,
allowing the radio to be used in the bedroom at night without the light from the
display keeping the user awake.
c. In the original user interface software, the display was set to a fixed contrast
setting. This may not have been ideal in all cases. The new software allows the
display contrast to be adjusted. This also has the effect of changing the optimum
viewing angle which may benefit users when the radio is located at different
heights.
3) Wi-Fi and Ethernet
a. The enhanced user interface software saves electrical power by shutting down
the Wi-Fi and Ethernet functions when not required. As a result battery life is
extended in some operating modes by approximately 50%.
b. The new software includes support for multiple Wi-Fi connection profiles (up to
four) thus making it easier to use the radio in multiple locations when it may
connect to different Wi-Fi networks.
In addition, this software update for the WM-202 includes a number of software stability and
router compatibility enhancements.
An updated version of the instruction book for the WM-202 which incorporates these features
and describes the enhanced user interface is now available from the Roberts Radio web site at
