It is strongly advised to put the probes on charge when they are

not in use, to avoid to reach a low charge level and not being

able to complete the exam.

The correct insertion polarity of the batteries is the following:

The “–” pole of the battery with the “VARTA” writing shall be face down

while inserting it in the slot.

If the probes are sold together with the Trumpet they will already be paired

with the device, otherwise before using them it is necessary to perform the

pairing procedure:

1. Connect the Trumpet to the power supply and to a USB plug on a

turned on PC;

2. Turn on the probes by pressing the transparent button in the center:

the LED will blink in blue;

3. Keeping the button on the probes pushed down put them in charge

position, then wait 3 seconds and release it;

4. After some seconds the probes LED will turn orange, indicating

the correct completion of the procedure. Now it will be possible to

use them for the exam.
