General Tools and Instruments WS831DL - Manual (Page 6)

NOTE: Alarm will automatically “snooze” if no buttons are pressed after the alarm sounds for 2
minutes.
This will occur three times only.
DISABLE ALARM(S):
Press ALARM/CHART to disable the alarm (s).
NOTE: For weekday alarm, pressing ALARM/CHART will only disable the alarm for the current day. The
alarm will activate again on the next day, Monday through Friday.
ATOMIC TIME RECEPTION
The purpose of the atomic clock is to provide consistently accurate time and date automatically. The
radio controlled clock searches for, and periodically synchronizes to, the NIST (National Institute of
Standards and Technology) Atomic clock signal transmitted from Colorado, throughout the entire
continental United States.
• During night-time hours, atmospheric conditions improve radio signal reception. A single daily
reception is sufficient enough to keep the clock accuracy within milliseconds.
• Unit should be positioned 8 feet (2 meters) from interference sources such as a TV, computer,
microwave, etc.
• The signal reception is weakened within concrete walls found in basements or office buildings.
Place the unit near the window for best reception.
Once the atomic time signal is received, the date and time will be set automatically, and the icon
will appear. Your atomic clock is programmed to search for the atomic time signal daily each hour
between 1:00 am and 4:30 am. Once the time signal has been successfully received, the time and date
will be updated automatically.
To manually enable or disable the atomic time receiver:
• Press and hold UP - if atomic time reception is activated, a triangular tower icon will start flashing
next to the clock icon. If reception is disabled, the triangular tower icon will disappear.

(no circle) Reception failed for 24 hours
(one circle) Weak signal, but can be decoded

REMOTE SENSOR STATUS
The wave icon above the current channel display shows the connection status of the corresponding
remote sensor:
Icon Status
Searching for the signals from the remote sensor
Corresponding remote sensor signal received successfully
No signals received for over 15 minutes
ACTIVATE SEARCH FOR REMOTE SENSORS
Normally the main display will automatically find and display measurement results from the remote
sensors. However, occasionally other radio transmission sources (TV, Cordless or Cell Phones etc) can
interrupt the sensor signal. If this happens simply press and hold the DOWN button to activate a search.
MEMORY RESET PROCEDURE
These steps will completely reset all of the parameters stored in memory.
• On the main unit press and hold SNOOZE and UP buttons for 4 seconds until the backlight
will flash.
• Press SET button clearing the memory -the main unit will start beeping with 1 second delay.
• Wait until the beeping will cease.
• Disconnect Remove the batteries from the back of the main display unit and wait 10 seconds.
• Reinstall the batteries.
MAINTENANCE
CHANGING BATTERIES
The battery status of each weather sensor is checked every hour. If the low battery indicator lights up,
replace the batteries in the corresponding unit.
CHANGING BATTERIES IN THE MAIN UNIT
• First connect the AC/DC adaptor provided to the main unit to avoid losing any data.
• Remove the battery compartment door at the back and replace all batteries. Do not mix old
and new batteries.
• Replace the battery compartment door.
CHANGING REMOTE SENSOR BATTERIES
• Replace the batteries following the setup instructions for the corresponding sensor.
• When the batteries are properly installed, the remote sensor will resume sending signals
to the main unit.
• To enforce an immediate remote signals search, press and hold DOWN on the main unit.
CLEANING
The main unit and remote sensor casings can be cleaned with a damp cloth. Small parts can be
cleaned with a cotton tip or pipe-cleaner. Never use abrasive cleaning agents and solvents. Do not
immerse units with electronic parts under water.
ANEMOMETER
Assure that wind vane and wind cups spin freely and are free from dirt, debris and spider webs.
RAIN GAUGE
Checking and cleaning the rain sensor in a timely manner will maintain an accuracy of the precipitation
measurements.
• Remove the protective screen and lid.
• Clean with soapy water and a damp cloth, removing dirt, leaves or debris.
• Clean small holes and parts with Q-tips or pipe-cleaner.
• Clean the swinging mechanism with a damp cloth.
TROUBLESHOOTING
Q: “The display shows dashes “—-” for weather parameter(s)”
A: The display will show “- - -” when the wireless connection with the remote sensor is lost for the
following periods:
Thermo-Hygrometer 15 minutes
Anemometer (Wind Sensor): 15 minutes
Rain Gauge (Rain Sensor) 30 minutes
Check or replace the batteries for the corresponding sensor. Then press and hold DOWN button on the
main unit to search for remote signals. If this does not work, check the wireless transmission path from
the corresponding sensor to the main unit and change locations to improve reception. Wireless signals
pass through solid objects and walls, however, whenever possible the sensor should be within
line-of-sight with the main unit.
The following may cause reception problems:
• The remote weather sensor and a main unit are too far from each other.
• The signal shielding materials, such as metal surfaces, concrete walls or dense vegetation, are in
the path of transmission.
• Interference from wireless devices such as: cordless phones, radio headsets and baby listening
devices or electronic appliances.
Q: “My weather station readings are different from TV, radio or official weather reports.”
A: The weather data may vary considerably due to different environmental conditions and placement
of the remote sensors.
If readings are in question, check the sensor placement tips included in this manual.
Q: “The weather forecast is inaccurate.”
A: Weather forecast predicts the weather for the next 12 to 24 hours, and does not reflect current
weather conditions.
PRECAUTIONS
This product is engineered to give you years of satisfactory service if handled carefully. Here are a few
precautions:
• Do not immerse the units in water.
• Do not clean the units with abrasive or corrosive materials that might scratch plastic parts or
corrode electronic circuits.
• Do not subject the product to excessive force, shock, dust, temperature, or humidity, which may
result in malfunctions, shorter lifespan, damaged batteries, and damaged parts.
• Do not tamper with the product’s internal components. Doing so will invalidate the warranty and
may cause damage. The product contains no user-serviceable parts.
• Use only fresh batteries. Do not mix new and old batteries.
• Read the user’s manual thoroughly before operating the product.
