Screen
The screen has a backlight feature to make it easier to see in certain
lighting conditions. This is activated while the phone is being used and
switches off after a period of inactivity.
The brightness of this backlight can be set for a personal preference. The
value is shown as a percentage. In addition the backlight can be disabled
if desired.
The brightness value is entered using the digits.
The settings must be applied before the change will be observed.
Volume
The volume screen provides a number of options related to the audio
configuration.
The main settings provide options to set the microphone and speaker gain
settings. These range between 1 (quiet) and 10 (loud).
These are the default volume settings used for future calls.
The volume can be adjusted for a particular call while it is
progress using the up / down keys. This is useful if a
particular call is too quiet or loud.
Separate volumes are provided for the handset (receiver), speaker and
headset. Values are entered using the numeric keys, with the up / down
keys used to navigate between the settings.
