Denso BHT-8000 User Manual page 79

Defining the function of M1 , M2 , M3 (left-hand trigger switch), or M4 (right-hand trigger switch)
key
Magic keys (M1 through M4)
The M3 and M4 keys are assigned the trigger switch function by default. You can make them function as
a SF key, ENT key, or backlight function on/off key.
If you define the M1 key as a backlight function on/off key, pressing the M1 key activates or deactivates
the backlight function.
In user programs, a string data can be also assigned to these magic keys.
The backlight function on/off key can be assigned only to any one of M1 through M4 keys. The key
defined more recently will act as a backlight function on/off key and one defined earlier will be
ignored.
That is, if you define the M1 and M2 keys as a backlight function on/off key in this order, the M2 key
will work as a backlight function on/off key and the M1 key's entry will be ignored.
Selecting the "2:M1 KEY," "3:M2 KEY," "4:M3 KEY" or "5:M4 KEY" on
the SET KEY menu calls up the screen as shown at left. (This
example appears when the "4:M3 KEY" is selected.)
