USER MANUAL
Powering your equipment:
Open up the battery compartment using the supplied screwdriver. Correctly insert two AA alkaline
or rechargeable batteries. The remaining battery level is displayed in the right hand top corner .
A full green battery in the right hand top corner means that the battery is fully charged. The equip-
ment's autonomy when fully charged will be around 7 hours.
The device can be powered through its USB port  with an external battery pack. Important: The
Checker turns off automatically when the battery power is insufficient to ensure proper operation,
or after 10 minutes of inactivity.
Connecting the sensor cable:
If necessary, connect the cable of the sensor to the device by lining up the red dot on the plug with
the red mark on the connector  and then inserting the plug into the connector.
To unplug them, move-up the knurled barrel of the plug without any rotating movement. Proceed
in the same way to connect and unplug the cable on the side of the flexible extension.
The ' ID' and 'Sensor ?' messages  indicate that no or an incompatible sensor is connected.
The "x"- "sensor" indication will only disappear when the Checker is correctly wired up and
connected to the correct sensor.
Using the Checker:
When pressing the on/off switch , the equipment will switch on immediately.
To switch off, the on/off button needs to be pressed for approx.. 2 seconds.
To take a correct measurement, the amplification needs to be adjusted for every reading in the
default screen. This is done by using the up and down arrows  and following the triangular
amplification guidance icons  in the top left hand corner of the display.
The current amplification setting is displayed here .
Once the correct amplification level is reached, the reading (measurement) will be displayed in
green and a "smiley" J will appear in the place where previously the triangular amplification
guidance icon was shown.
When the reading (measurement) is displayed in red, the amplification is too high and will need to
be reduced by pressing the "arrow down" button.
When ''-.-'' is displayed on the default screen or in orange in the streaming mode, the amplification
is too low and will require increasing by pressing the "arrow up" button. In both cases, i.e. when
the amplification is too low or too high, the amplification should be adjusted until the reading
(measurement) is displayed in green and the smiley J appears in the left hand top corner.
To switch between the default screen and the streaming screen press the on/off button  once.
An histogram giving a brief history of the measurement is dynamically displayed. The amplification
adjustment is not available anymore.
To update the firmware of your Checker, download the SDT Updater software on our website and
install it using the provided usb cable.
Using the headphones:
To enhance the hearing experience, the audio volume of the headset can be adjusted by pressing
the left and right arrows  until the sound level is comfortable.
Avoid setting the sound too low as otherwise some signals may not be heard and possible leaky
spots overlooked. Connect the headphones here .
The current volume setting is displayed  only when a headset is connected.
