Operating instructions
For controlling all functions is used one operating button and multifunctional LED. This
button works in single click mode, where each click must be at least 3 seconds long. In case
of selecting optional double click mode, it requires one click in length of at least 3 seconds
followed by pause in length of 1 second and second same click again.
When the battery is inserted, one short LED flash must follow after about 5 seconds. If this
single flash is not observed, use fresh battery instead of partly discharged or check battery
contacts.
Start and stop the recording
Using operating button activates those actions. Before the recording starts, the LED flashing
sequence will follow. When it flashes only ones, the memory is full and recording can’t be
started. Flashing 2 to 4 times indicates available memory space. (4 flashes – more than 75%
space available, 3 flashes – more than 50% space available, 2 flashes – less than 25% space
available). The recorder should store up to 255 records. If this count has exceeded, the
memory is considered as full. When the recording is in progress, the LED makes short flash
each 2 seconds. This function should be disabled for discrete recording. When the voice-
activated recording is enabled, the LED flashes only, when the sound level is above selected
threshold and recording is in progress. The recording is stopped when the memory is full or
by pressing the operating button. 3 LED flashes indicate stop sequence. This sequence is
followed after about one second, when you press operating button. To recognize clearly this
state, this sequence of 3 flashes is followed during the time when you hold the button (when
you start recording by using the button LED flash sequence starts after you release the
button).
Battery types
For longest battery life in recording mode the Zinc-air batteries must be used. Recommended
type us ZA675 or PR44. Optionally alkaline 1,5V batteries of the same size should be used,
but the battery life will be shorter.
