Is the red L.E.D flashing? The L.E.D flashes once every 10 seconds and may be difficult to see in a well lit area.

Is the correct version of software being used? The minimum requirements for this product are as follows: DicksonWare 6.0.3.0 or higher.

Is the correct COM port selected? Try another available COM port connection on back of PC. If this is the first time attempting to communicate on this PC, or if new software or programs have been installed since the logger was last used, try installing the software on another PC not a laptop). Check Com port allocations in the PC’s Device Manager, make sure the COM port you’re trying to use is not “”””reserved”””” for something else. Open the logger and depress the “”””RESET”””” button for about 5 seconds while still connected to the PC, then try all COM ports again.

D118, D119, D120

The telephone number may be incorrectly programmed. Tone or Pulse (the current dialing method) is not compatible with the telephone line on which the D118/D119 is installed. The recognition time is too long.

An alert condition does not remain in effect long enough to become a valid alarm. The max number of calls is set to zero. It’s a best practice to set your max calls to at least equal the number of dial-out telephone numbers programmed. The unit must be connected to a standard (2-wire analog) telephone line, not a digital extension to a phone system. If the unit will not dial out and the factors previously listed have been ruled out, try connecting the unit to standard residential telephone line.
