3. Setup Guide
3.1 Battery Installation:
Note: To avoid operating problems, please take note of battery polarity be-
fore/when inserting any Alkaline Batteries (permanent damaged could be
introduced by inserting the battery in wrong direction). Use good quality Alkaline
Batteries and avoid rechargeable batteries.
1) Insert two AAA batteries into the remote sensor.
2) Insert three AA batteries into the weather station straight afterward.
3) Within 3 minutes (but probably sooner) the outdoor temperature
should be received by the weather station. Do not press any keys
before the outdoor sensor data is received.
4) Once the outdoor connection has been established, mount the units
ensuring that the receiver can still pick up the signal from the
transmitter. Position the remote sensor at the desired location
indoors/outdoors and it will transmit the temperature from its location.
Every time the remote sensor is powered up (for example after a change of
batteries) a random security code is transmitted that must be synchronized with
the base station to receive weather data. Therefore, if the batteries from the
remote sensor were changed, then the display console must also be powered
up again to re-learn the transmitter so it can receive data. The most effective
way to do this is to remove all batteries from both parts, wait one minute with
both units unpowered, then re-insert all batteries again within a 30-second time
period.
When the display console is powered up, a short beep will sound and all LCD
segments will light-up for 3 seconds before it enters learning-mode in order to
identify the remote sensors security code. Following this period, the base
station will then start the DCF radio controlled time reception. The console will
commence Radio-Controlled Clock reception period and no weather data
will be received during this period of time. If the RCC signal can’t be found
within 1 minute, the search process will be cancelled and will automatically
re-attempt every two hours until the signal is successfully received. The regular
radio-frequency link will be resumed once the RCC reception routine has been
completed.
05

CM9088 Wireless Desktop Weather Station
3.1 Battery Installation Continued:
Note: Please make sure not to press any keys during the initial learning-period
– if a key is pressed before the station receives the temperature signal, you will
need to follow the battery installation procedure again.
Please wait 10 seconds before re-inserting the batteries in order to ensure
both the transmitter and receiver have been allowed to completely reset.
Note for Radio Controlled Time:
The time and date display is based on the signal provided by the highly accurate
government operated atomic clock based in Frankfurt, Germany. The display
console will continue to scan for the radio controlled time signal each day, even
if the time has been set manually. If this reception has been unsuccessful, the
radio controlled time icon will not appear but reception will still be attempted
continually. If reception has been successful, the received time and date will
overwrite the manually-set time and date. If after setting the time manually
it appears to then ‘jump’ forward, it is possible that the unit has received
the radio-controlled time and overwritten the manual time setting. If this
happens, please check the Time Zone setting, as you may need to adjust this to
compensate for international time difference. To do this, press and hold the
SET key until the time changes to a flashing single digit (this will display ‘0’ by
default). Then, press either the ‘+’ or ‘MIN/MAX’ key to change the time zone
setting up and down accordingly.
Note: When batteries require replacement for the display console the low
battery indicator will light up on the LCD.
3.2 Sensor Installation:
1) Display Console
Using the foldable legs at the back of the unit, the
base station can be placed onto any flat surface.
It can also be wall mounted at the desired
position by using the hanging holes also found
at the back of the unit. It’s important to check
that the radio signal can be received successfully
before permanently mounting either of the
units.
06

CM9088 Wireless Desktop Weather Station
3.2 Sensor Installation Continued:
2) Remote sensor
Note: To achieve a true temperature reading, please try to avoid mounting
the remote sensor in direct sunlight. The outer casing of the sensor could
potentially heat up and then take time to cool again, resulting in false
temperature readings. We recommend that you install the remote sensor on
an outside North-facing wall. Remember that some obstacles such as thick
walls, concrete and large metal objects can reduce the transmission range.
To wall mount, use 3 screws to fix the wall bracket to the desired wall and then
simply plug the remote sensor into the bracket.

4.1 Weather Forecasting:
The four weather icons Sunny, Partly Cloudy, Cloudy and Rainy are used for
weather forecasting. There are also two weather tendency indicators to show
the air pressure tendency between the displayed weather icons. The weather
forecasting is calculated from the changing air pressure.
4.2 Weather Tendency Indicator:
The weather tendency indicator arrow is located between the weather icons to
show the air pressure tendency and to provide a forecast of the upcoming
weather. The rightward arrow means that the air pressure is increasing and
weather is expected to generally become better. The leftward arrow means that
the air pressure is decreasing and the weather is expected to become worse.
The weather forecast icon is in accordance with the calculation between the
current relative-pressure and the on-going pressure change over the last six
hours. If a change is occurring, the weather tendency indicator (animated
arrows) will be flashing for three hours indicating that a change in the weather
is underway. If weather conditions have then become stable and no new
weather change conditions are met, the arrows will be fixed.
4.3 Examples of Changing Weather Icons:
4.4 Storm Warning Indicator:
The storm threshold can be set to suit the user’s requirement for storm
forecasting, from a sensitivity of between 3-9hPa (default 2hPa). Areas that
experience frequent changes in air pressure generally require a higher setting
compared to an area where the air pressure is calmer. For example, if 4hPa is
selected there must be a fall or rise in air pressure of at least 4hPa before the
weather station will register this as a change in weather.

5.3 Setting Calibrated Humidity:
The display console allows you to calibrate both the indoor and outdoor
humidity. Humidity is a difficult parameter to measure accurately and drifts over
time - the calibration feature allows you to compensate for this. To calibrate
humidity, you will need an accurate source, such as a sling psychrometer or
whirling hygrometer.
To calibrate indoor humidity - In the Setup Mode with the indoor humidity
flashing, press the +key or the MIN/MAX key to increase or decrease the
humidity setting (in increments of 1%) to match the known humidity source. To
return the indoor humidity to the measured value, press and hold the SET key
for 3 seconds and the humidity will return to the uncalibrated value.
To calibrate outdoor humidity - In the Setup Mode with the outdoor humidity
flashing, press the +key or MIN/MAX key to increase or decrease the humidity
setting (in increments of 1%) to match the known humidity source. To return the
outdoor humidity to the measured value, press and hold the SET key for 3
seconds and the humidity will return to the uncalibrated value.
Note: The remote thermo-hygrometer will always display the measured
humidity level and not the calibrated humidity level. Only the console will show
this calibrated value.
Note: The dew point calculation is based on the calibrated humidity level.
14

CM9088 Wireless Desktop Weather Station
5.4 Setting Barometric Pressure:
The display console displays two different pressures: absolute (measured) and
relative (corrected to height above sea-level).
To compare pressure conditions from one location to another, meteorologists
correct pressure to sea-level conditions. Because the air pressure decreases as
you rise in altitude, the sea-level corrected pressure is generally higher than your
measured pressure.
Therefore your absolute pressure may read 28.62 inHg (969 mb) at an altitude
of 1000 feet (305 m), but the relative pressure is 30.00 inHg (1016 mb).
The standard sea-level pressure is 29.92 in Hg (1013 mb). This is the average
sea-level pressure around the world. Relative pressure measurements greater
than 29.92 inHg (1013 mb) are considered high pressure and relative pressure
measurements less than 29.92 inHg are considered low pressure.
To determine the relative pressure for your location, locate an official reporting
station near you (the internet is the best source for real time barometer
conditions, such as weather.com or wunderground.com), and set your weather
station to match the official reporting station.
To change this, while the relative pressure is flashing press the +key or
MIN/MAX key to increase or decrease the relative pressure setting to match the
official reporting station.
