I recently purchased the 5 in 1 sensor 06016 and 06004. The display 06016 keeps resetting date and time. Even have trouble setting date and time because it resets before completed. Called customer service sent a new power supply. Still have the same problem.
Sounds like it is a chip problem. Try removing the power source. Then all batteries. Wait a minute and put in batteries ONLY and try setting it up and see what happens. If still won't set, then send it back for repair.
To do a factoryreset: (THIS WILL CLEAR ALL OF YOUR HISTORY AND YOUR SETTINGS)
Please verify that you are using a name brand (Rayovac or Energizer) standardalkaline batteries in the display unit. We do not recommend using anything thatis heavy duty, rechargeable, store brand or Lithium inside of the display.
- Remove all power, AC adapter and batteries, from the display unit. - Press and hold down the pin hole reset button, located in the batterycompartment, for 20 seconds. - Plug back into AC power and insert recommended batteries. - Press and hold down the pin hole reset button for an additional 20seconds. - Verify that the unit has powered on and once connection has been made,attempt to set time and date.
