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 - where indicated - 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. Do not press the On/Off power button again while waiting for the blue light to come on or at any time while the Callfinder® is in use.
