How to Switch between different sound files More than one sound file can be stored on your Callfinder®.
The .bnl sound files on the Callfinder® are not stored in a specific order. Therefore, there may be a time lapse switching from one sound file to another.

Remember: Only the photos in SAPPI Birds of South Africa and in The Mammal Guide of Southern Africa are sound activated, not the text. Both the illustrations and text are sound activated in Blinktand van Bosveldparadys.
Step 1: Switch the Callfinder® on by pressing and holding the On/off switch for 3 seconds - a blue indicator light will come on which indicates that the Callfinder® is ready to be used.

Step 2: Switching from one sound file to another.

Touch the front cover with the Callfinder® tip for approximately 8 seconds. The specific book's sound file will be activated.
Allow 3 to 4 seconds before touching a photo and/or text (where applicable) in the book.
Switch to another sound ready book by repeating the procedure. A short time lapse may be experienced when switching from one .bnl sound file to another.
