Defining a function key as the LCD backlight function on/off key

You can define a particular function key as the backlight function on/off key and set the length

of backlight ON-time by using the

KEY statement, as shown below.

- Example for defining the key numbered 5 and setting 60 seconds.

KEY 5,"BL60"

■ Defining a magic key

BHT-5000/BHT-6000/BHT-6500

You can define a magic key as the SF key, trigger switch, or battery voltage display key, as well

as assigning a character string, control code, ENT key, or backlight function on/off key to it. (In

the BHT-6000, the trigger switch function is assigned to both M1 and M2 keys by default; in the

BHT-6500, it is assigned to all of M1 to M4 keys by default.)

- Example for defining the M1 key as the SF key.

KEY 30,"SFT"

- Example for defining the M2 key as the trigger switch.

KEY 31,"TRG"

- Example for defining the M1 key as the battery voltage display key.

KEY 30,"BAT"

BHT-7000/BHT-7500

You can define a magic key as the SF key or trigger switch, as well as assigning a character

string, control code, ENT key, or backlight function on/off key to it. (The trigger switch function

is assigned to both M3 and M4 keys by default.)

7.2.2 Keystroke Trapping

You can trap the pressing of a particular key, by programming with the KEY ON, KEY OFF, and

ON KEY...GOSUB statements.

For details about the keystroke trapping, refer to Chapter 9, "Section 9.2, "Event Polling."

NOTE

It is impossible to assign both a character string and the backlight on/off function to a

same function key. For details, refer to KEY in Chapter 14.

NOTE

If you specify a function key which has been defined as the LCD backlight function

on/off key, trigger switch, shift key, or battery voltage display key for keystroke trap-

ping, no keystroke trap takes place.
