Please check the actual Caps Lock state in use while software application is running. If the Caps Lock state is 
off, select “Caps Lock Off” state, and then the Hand-held scanner will perform normal data transmission. If 
the Caps Lock state is on, select “Caps Lock On” state. If “Auto Detect” is selected, the Hand-held scanner will 
perform special transmission handshaking without changing the status of Caps Lock switch.

Intermessage Delay: is a time delay between messages outputted by the Hand-held scanner. Increasing this 
delay will help host applications to process the incoming data on time. 
 
Intercharacter Delay: is a time delay between data characters outputted by the Hand-held scanner. These two 
parameters are used to synchronize data communication when: 1) the data transmission speed is too fast, 
characters may be skipped; 2) multitasking operation system or host computers in a network may slow down 
the keyboard handling; 3) various notebook or desktop PC systems require different timing parameter 
settings. It is recommended to always add one extra unit as safety margin when adjusting these two 
parameters. 
 
Interfunction Delay: is a time delay of between transmission and reception of each segment of the message 
string. 
 
Intermessage, Intercharacter and Interfunction Delay are not available for IDM Bluetooth scanners 
working in SPP or HID mode.
