2. Press the MIN/ MAX button once. The "max" icon will be displayed.
3. Press the SET button; this will reset the outdoor maximum temperature and
humidity record to the current value.

915 MHz RECEPTION
The Weather Station should receive the temperature data within 15 minutes after set-
up. If the temperature data is not received 15 minutes after setting up (not successfully
continuously, the outdoor display shows “- - -” ), please check the following points:
1.
The distance of the weather station or sensor should be at least 1.5 to 2 meters
away from any interfering sources such as computer monitors or TV sets.
2. Avoid positioning the Weather Station onto or in the immediate proximity of
metal window frames.
3. Using other electrical products such as headphones or speakers operating on
the same signal frequency (915MHz) may prevent correct signal transmission
and reception.
4. Neighbors using electrical devices operating on the 915MHz signal frequency
can also cause interference.
Note:
When the 915MHz signal is received correctly, do not re-open the battery cover of
either the sensor or Weather Station, as the batteries may spring free from the contacts
and force a false reset. Should this happen accidentally then reset all units (see
Setting up above) otherwise transmission problems may occur.
The transmission range is about 330 feet (100 m) from the sensor to the Weather
Station (in open space). However, this depends on the surrounding environment and
interference levels. If no reception is possible despite the observation of these factors,
all system units have to be reset (see Setting up).
