TO ACCESS THE MIN OR MAX VALUES (CONTINUED):

When pressing the “MAX” button, the unit will show the maximum value for all the records in the upper display window. Values in the upper display window are as follows; Outdoor tempera- ture, outdoor humidity, indoor temperature, indoor humidity, wind speed average, wind speed gusts, the selectable display item and barometric pressure. Barometric pressure is displayed in the lower display window.

NOTE: To show min/max values for wind chill, heat index, or dew point (the selectable display area), the value of interest must first be displayed by pressing the “DISPLAY” button until the desired value is displayed.

DAILY RECORDS:

The Daily Record is a feature that displays a single value with the date and time of its recording. When the daily record is being displayed, the value, date and time will be blinking. When the unit is in a daily record mode, the unit will display a blinking “dr” next to the time of the recording, indicating Daily Record. The main unit automatically stores the last seven days worth of recordings.

TO ACCESS THE DAILY RECORDS:

While in either the “MIN” or “MAX” mode, press the “DAILY RECORD” button to show either the “MIN” or “MAX” for any of the values shown in the graph below. Continue to press the “DAILY RECORD” button to scroll through each of the values shown in the graph below.

To review the history of a blinking value, press the “-“ or “+” button to scroll backwards and forwards within the last seven days of recordings. The value, date and time will update to show when the record occurred.

NOTE: While reviewing the history for a certain value, pressing the “DAILY RECORD” button automatically returns the unit to the present-day next value as shown in the graph below.

NOTE: Pressing the “exit” button at anytime, returns the unit to normal operating mode.

NOTE: Daily records can not be cleared; they automatically adjust on the seven day cycle.

TO ACCESS THE LONG-TERM RECORDS:

While in either the “MIN” or “MAX” mode, press the “RECORD” button to show the long-term record highs or lows of the weather station. These values may have occurred anytime in the history of the weather station. These values show the highest or lowest values ever recorded on the weather station.

To review long-term records, press either the “MIN” or “MAX” button, then press the “ON/OFF/RECORD” button to show the highest or lowest value, at this point, the unit will display a blinking “Lr” in the second’s window and the unit will show all the record values. To obtain the historical details for these records, press the “ON/OFF/RECORD” button and the record, along with time and date will be blinking. Press the “ON/OFF/RECORD” button again to scroll through each of the unit’s minimum and maximum record values.

CLEARING LONG-TERM RECORDS:

MAINTENANCE

Clean the housing and screen of the base station only with a soft damp cloth. Do not use abrasives or solvents. Do not submerge in water.

•Clean the outer housing of the thermo-hygrometer sensor with a soft damp cloth. Do not use abrasives or solvents. Do not take sensor apart. Do not clean funnel of sensor. Do not submerse sensor under running water.

•Clean the wind speed and direction sensor only with a soft damp cloth. Do not take sensor apart. Do not use abrasives or solvents. Do not submerge in water.

•Should there be damage to any part of main unit and/or sensors, do not attempt to repair, as this will result in loss of any manufacturer guarantee. Please send damaged part(s) to manufac- ture for repair/replacement. Manufacturer information is located at the end of this user manual.

GENERAL CARE OF MAIN UNIT AND WIRELESS SENSORS:

•Avoid exposing main unit and wireless sensors to extreme temperatures, keep out of direct sunlight away from water or severe shock.

•When the outside temperature falls below -4ºF, the batteries in the wireless sensors may not produce enough current to power the transmitter, if this happens, the main unit will not show an outdoor temperature reading. We recommend the thermo-hygrometer wireless sensor be brought indoors during prolonged periods of sub-freezing temperatures.

CHANGING BATTERIES

MAIN UNIT BATTERY REPLACEMENT: When the low battery indicator icon becomes present, it is recommended that you change the batteries. Replace only with the same or equivalent type of fresh alkaline batteries. This method of battery replacement ensures there will be no loss in MIN/MAX and history data. However, if main unit or sensors have remained without batteries for an extended period of time, the main unit will lose the MIN/MAX and all weather data recordings and will have to be synchronized again.

NOTE: When replacing batteries, do not mix battery types or old batteries with new ones.
