+ * Temperature                -40 .. +85 C
+ * +5V                      +4.75 .. +5.25 V
+ * +5V standby              +4.75 .. +5.25 V
+ *
+ * LCD backlight is not enabled if temperature values are not within
+ * allowed ranges (-30 .. + 80). The brightness of backlite can be
+ * controlled by setting "brightness" enviroment variable. Default value is 50%
