Sign Brightness Adjustment Feature (<F1>)
The default brightness setting is ―0‖ (zero). This means the sign is set for automatic brightness
adjustability and depending upon the ambient light directed to the sign, there are 16 possible brightness
levels. To manually change the automatic brightness to another value, perform the following steps:
(1) Press <F1> and the second level access code screen will appear (see Figure 20).
(2)
Using the numeric keypad enter access code number ―1221‖ and if the access code is correct,
the second level key mode screen will appear as shown in Figure 21.
(3) Referring to Figure 22, press <F1> again and the display selection screen will appear (depending
of your current settings, different values may be shown).

(4) Press the number of sign to be changed. Note that the numeric choices are equivalent to the
alphabetical choices, so that, in this example 1 = (A-front sign), 2 = (B-side sign), 3 = (C-rear
sign, etc.). The choices of your own particular system may be different from what is shown in
Figure 22 and Figure 23. In Figure 22 the signs are A, B, and C and the corresponding existing
valu
es in this example are each ―5‖ (the values are vertically below each sign letter designation).
