OPERATION
ON/OFF Protection
To turn the TDS-II on or off, press and hold the ON/OFF button for one second. This slight delay
protects against inadvertently triggering. If you forget to turn it off, the TDS-II will automatically
turn itself off after 10 minutes of no activity to conserve battery charge life.
LED Bar Graph Display
The eight segment LED display indicates the degree of detection. As the concentration of
termite off gases detected increase so will the number of lit bars on the display.
L/M/H Buttons (Sensitivity)
Set the sensitivity level by pressing the L/M/H button. The desired sensitivity level will be
indicated by its respective LED. The TDS-II starts in medium (M) level, which is a sufficient
sensitivity for normal colonies of termites commonly found in the subterranean species. The
high sensitivity (H) is reserved for more difficult detections of small swarms such as dry-wood
termites. The low (L) sensitivity is used when large concentrations are present and the user is
trying to isolate to specific areas of a concentration. The TURBO super high sensitivity is
recommended when testing for bed bugs.
MUTE Button
Pressing the MUTE button toggles the audio of the TDS-II off and on.
PEAK Button
The PEAK button holds the highest LED lit during a detection event. Press PEAK again to
toggle this function on and off. Turning the PEAK function off will clear the peak bar graph LED
that is lit. The PEAK LED will light when this function is on. The peak button is also used to put
