[. . . ] Do not place the sensor more than 100 meters (328 feet) from the main (indoor) unit. Minimize obstructions such as doors, walls, and furniture. The sensor range is up to 100 meters (328 feet) with no obstructions, but if the main unit has a shorter range than the sensor, you may have to move the sensor closer for reception. You may need to experiment with various locations to get the best reception. This icon will blink on the main unit UV value display box when it searches for the sensor. NOTE Once the batteries are in place, the sensor will transmit signals every 40 seconds. It will take over an hour before all measurements on the main unit are displayed (e. g. UVI history) because some measurements are hourly averages. 6 UVR138 English r8 6 10/15/03, 11:24 PM RESET The RESET button is located near the battery compartment. Press it whenever you change the batteries, or whenever performance is not behaving as expected (e. g. , unable to establish radio frequency link with the main unit). This will return all settings to default values, and you will lose all stored information. Based on readings transmitted from the sensor, the main unit can calculate maximum sun exposure times before the skin starts to burn. Calculations are updated every time a new UV reading is received from the sensor. This calculation is based on three factors: · · · SKIN TYPE (user-selectable) SPF (user-selectable) UV DATA (collected by sensor) BACKGROUND INFORMATION NOTE The following settings and information only apply if you have an Oregon Scientific compatible weather station. On the main unit weather station, UV readings are recorded and interpreted in two areas of the display: 1. UV bar chart display. SPF (Sun Protection Factor) Individuals react differently to sun exposure. The SPF indicates the level of protection needed when time is spent under the sun. The selectable SPF range is between 1-50 and relates to how susceptible you are to getting sunburn. Enter an SPF setting that corresponds to the SPF protection you choose for your sunscreen products. · · · 1-11 (low protection) 12-29 (moderate protection) 30-50 (high protection) 2. The UV value display. 7 UVR138 English r8 7 For example, if your skin is sensitive and you get sun burnt easily, you will need a lot of protection from the sun's UV rays. In this case you should use a sunscreen with an SPF rating of 30-50 for maximum safety, then input the respective SPF in the main unit setting for accurate calculation. 10/15/03, 11:24 PM EN EN UV INDEX BAR CHART DISPLAY The UV index bar chart shows ultra violet level patterns taken over ten hours. Ultra violet level readings are taken hourly, averaged, and then displayed as an index. Measurements are displayed in 2-hour increments (-10, -8, -6, -4, -2, 0). For example, (-10) indicates the average hourly reading taken ten hours ago, (0) is the most current average. [. . . ] For example, the average UV index recorded ten hours ago is indicated by a (-10), the most current average is (0). NOTE If no keys are pressed within 10 seconds, the value displayed will revert to the most current index (0). 2. Press CHANNEL to display UVI Exposure time. 10 UVR138 English r8 10 10/15/03, 11:24 PM TROUBLESHOOTING Symptom (----) "LOST LINK" is displayed Remedy On the main unit press and hold CHANNEL and MEMORY in UV mode to manually force a UV sensor search Wait 2 hours so main unit can collect enough data for an average Press the remote sensor RESET button Main unit cannot locate Check batteries remote unit: Make sure they are not too far apart icon blinks Press the remote sensor RESET button UV sensor readings Make sure the sensor is not in the seem too low shade. Place in an area with maximum exposure to the sun Make sure UV sensor isn't covered by dirt. [. . . ]
