[. . . ] Either 1m (3ft) or 3m (10ft) can be selected for the resolution. The altitude will be updated according to the resolution selected. Press and hold SET for two seconds in altitude-clock display to enter the altitude setting mode. Press SET to toggle to the resolution of altitude setting mode. Press +/- to select the desired resolution (1m/3m or 3ft/10ft) 4. Press SET to confirm the setting and quit the setting mode. Refer to Fig 4b to set the resolution of altitude. Note: SET SET +/- SET Fig. 4b · Press and hold +/- function is not available for select the resolution of altitude. Fig. 4a Notes: a) The correct local altitude could be found from a topographical map. b) Setting the altitude affects the sea level pressure displayed. c) The altitude can be calibrated by setting the sea level pressure. For details please refer to section HOW TO SET THE SEA LEVEL PRESSURE. HOW TO SET THE ALTITUDE ALARM RA201 is equipped with an altitude alarm. Either ascending or descending altitude alarm could be selected. the ascending altitude alarm will be turned on whenever the set altitude is reached during ascending from an ascending path. The descending alarm will be turned on whenever the set altitude is reached during descending from a descending path. Press and hold SET for two seconds in altitude-altitude alarm display to enter the altitude alarm setting mode. Press +/- to select either ascending or descending altitude alarm. Press SET to confirm the setting and toggle to set the altitude. Press +/- to set the altitude for the altitude alarm. Press SET to confirm the setting and then quit the setting mode. Press LAP/- to turn the altitude alarm on/off. Refer to Fig 4c to set the altitude alarm. Set acsending/descending alarm HOW TO SET THE WEATHER FORECAST ICON Apart from determining the altitude, barometer also forecasts the weather for the forthcoming 12 to 24 hours based on barometric pressure changes. To have a faster response of the weather forecast, it is suggested to set the weather forecast icon to match the current weather. [. . . ] Doing so will terminate the unit's warranty and may cause damage. The unit contains no user-serviceable parts. a) After key lock function is activated, only LIGHT key can function normally. 20 TROUBLE SHOOTING GUIDE TROUBLE Different altitude was found for same location in different days. POSSIBLE CAUSE This is caused by the pressure changes due to the activities instead of the actual sea level pressure change. The altitude exceeds the upper limit of the display range of the bar graph. (1) Battery has changed. REMEDY Recalibrate the altitude by setting the sea level pressure. After changing the unit of measurement, the historical readings of the sea level memories were shown constant. [. . . ]
