Maintenance
Changing Batteries
The battery statuses of the sensors are checked every hour. If the low battery indicators light up,
replace the batteries for the corresponding unit immediately.
Changing Batteries for the Main Console Unit
1. To avoid losing data and records, connect the AC/DC adaptor to the main unit first.
2. Remove the latch at the back and replace all batteries. Do not mix old and new batteries.
3. Replace the cover.
Changing Batteries for the Remote Sensors
1. Replace the batteries following the setup instructions for the corresponding sensor.
2. When the batteries are properly installed, the sensor will resume sending signals to the main
console unit.
To enforce a search immediately for all remote signals, press and hold
DOWN
on the main
console unit.
Cleaning
The main console unit and outer casings for the remote sensors can be cleaned with a damp cloth.
Small parts can be cleaned with a cotton tip or pipe-cleaner.
Never use any abrasive cleaning agents and solvents. Do not immerse any units with electronic parts
in water or under running water.
Anemometer
- Check that the wind vane and wind cups can spin freely and are free from dirt, debris or spider
webs.
Troubleshooting
The display shows dashes “---” for weather parameter(s)”
The display will show “---” when the wireless link is lost with the remote sensor for the following
periods:
Thermo-hygro Sensor – 15 minutes
Anemometer (Wind Sensor) – 15 minutes
Check or replace the batteries for the corresponding sensor. Then press and hold
DOWN
to enforce
a search for all remote signals.
If the above does not solve the problem, check the wireless transmission path from the corre-
sponding sensor to the main console unit and change their locations if necessary.
Although wireless signals can pass through solid objects and walls, the sensor should ideally be
within the line of sight of the console unit.
The following may be the cause of reception problems:
- Distance between remote sensor and main console unit too long. (Maximum transmission distance
in open area conditions is 100m)
- Signal shielding materials such as metal surfaces, concrete walls or dense vegetation in the path of
transmission.
- Interferences from wireless devices (such as cordless phones, radio headsets, baby listening
devices) and electronic appliances.
The weather readings do not correlate with measurements from TV, radio or official weather reports.”
Weather data can vary considerably due to different environmental conditions and placement of
weather sensors.
Check the placement tips included in this manual to site your sensors in the best possible way.
“The weather forecast is inaccurate.”
The weather forecast is a prediction of weather after 12-24 hours, and may not reflect current
weather conditions.
PRECAUTIONS
This product is engineered to give you years of satisfactory service if you handle it carefully. Here
are a few precautions:
1. Do not immerse the unit in water.
2. Do not clean the unit with abrasive or corrosive materials. They may scratch the plastic parts and
corrode the electronic circuit.
3. Do not subject the unit to excessive force, shock, dust, temperature or humidity, which may result
in malfunction, shorter electronic life span, damaged battery and distorted parts.
4. Do not tamper with the unit's internal components. Doing so will invalidate the warranty on the
unit and may cause unnecessary damage. The unit contains no user-serviceable parts.
5. Only use fresh batteries as specified in the user's manual. Do not mix new and old batteries as the
old ones may leak.
6. Always read the user's manual thoroughly before operating the unit.
