• Press {Ch Up or Ch Dn} key to select the desired service menu item.
• Press {Volume (+/-) to increase or decrease the data sequentiality.  The number keys (0 to 7) toggle only their respective bits, between (1) and (0), and are used to change the sub-address.  For example:  to change bit [5]:

----------------------------------------------------------------------------------------------------------------------------------

(b7)  (b6)  (b5)  (b4)  (b3)  (b2)  (b1)  (b0)

 0        1      0       1       0      1       1      0  <---------------8 bit binary data.  

To select, use {Channel Up | Channel Dn}. 

NB:  Using (+) or ( - )  is not recommended due to possible rapid changes.
