[. . . ] This icon will blink on the main unit UV value display box when it searches for the sensor. It stops blinking when the sensor has been found. 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. Each calculation can be customized for a specific user (1-4). 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. Readings will show approximately one hour after you setup the sensor. USER SETTINGS Under the same exposure to the sun, individuals will react differently. [. . . ] This can cause electrical shock and damage the unit. Do not subject the main unit to extreme force, shock, or fluctuations in humidity. Do not tamper with the internal components. Do not mix new and old batteries or batteries of different types.
