I've got a model 00638. All the buttons work, and the unit has been very reliable. However, now it seems that the History/Mode button seems unresponsive. The only history that I can look at is barometric pressure. I tried resetting the display, to no avail. Any thoughts?
We would recommend doing a factory reset on the display. If that doesn't correct the issue, and you have had it less than 1 year we would initiate a warranty claim on the display. The factory reset instructions are below:
To do a factory reset: (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.
