Troubleshooting - HoMedics EnviraStation DWS-320 Instruction Manual And Warranty Information

DWS-320-IB_ENG\SP 10/12/04 11:38 AM
• Once a channel is registered, it will not accept any new sensors. However,
registered channels can be erased by removing the batteries in the remote
sensor or the home unit.
• When replacing batteries for the remote sensor - Remember to clear the corre-
sponding channel of the home receiver by removing the batteries or selecting the
respective channel of the sensor by pressing the CHANNEL button on the home
receiver. Hold the CHANNEL button for 3 seconds to clear the registration.
• When replacing batteries for the home receiver - Please remove the batteries of
all remote sensors. Once you have replaced the home receiver batteries,
re-install the batteries to the sensors and re-log them in again. This will ensure
that the home receiver and the remote sensors are properly synchronized.
• Press the TX button on the back of remote sensor to verify the RF reception.
• It is recommended to test the home receiver and the remote sensor next to each
other to ensure that both are properly synchronized.
• Keep the remote sensor out of direct sunlight and rain. Do not mount on a metal
surface.
About the Atomic Clock
The National Institute of Standard and Technology (NIST) in Fort Collins, Colorado
broadcasts the time signal (WWVB at 60kHz AM radio signal) with an accuracy of 1
second per every 3,000 years. The signal will cover a distance up to 2,000 miles
from the source. Like a typical AM radio, your Atomic Clock will not able to receive
the WWVB signal in places surrounded by heavy concrete or metal panels. The
reception of the time signal can be affected by mobile phones, TV, electrical
appliances or other electronic interference. To get the best performance of the
Atomic clock, please install the home receiver near a window and away from large
metallic objects. If the unit is not working properly, change the unit position. There
may be some interference at this location.
TROUBLE SHOOTING
Indoor and Outdoor temperatures do not match when placed
next to each other -
Each sensor is manufactured to be +/- 2 degrees in accuracy under normal con-
ditions. So it is possible to have up to four degrees difference shown on the
separate temperature sensors (one could be "+2 degrees" and the other "-2
degrees". Additionally, the calibration curve is different between the two units
because of the greater temperature range of the outdoor sensor. Errors are usually
noted on the extreme ends of the temperature ranges.

Base unit is not accepting remote transmissions -
The units may not be properly synchronized or the batteries may need to be
replaced. See "GETTING STARTED" section beginning on page 2 of the
instructions for detailed instructions. With the two units next to each other,
attempt synchronization. Remember to always place the remote sensor
within the effective transmission range and away from large metal surfaces.
What is the recommended battery type?
We recommend using only alkaline batteries for replacements.
Where can I mount the remote sensor?
To get accurate readings and to prolong the life of your sensor, we rec-
ommend that you mount it out of direct sunlight and rain. Fog and mist will
not affect the sensor, but large volumes of soaking rain may. To guard
against this, we recommend that you mount it under the eve of your house,
your garage or any other suitable place that will keep it out of direct sun
and rain.
Outdoor Temperature Reading shows "- -"
This is usually an indication that the channel selector (located in the top left
corner of the home receiver) is set incorrectly to receive the signal from the
remote sensor. If you have only one remote sensor, ensure that the channel
selector is set to "1". To change the channel, press the "channel" button
located on the back of the home receiver.
The home receiver may also be "scrolling" - looking for sensor readings from
more than one remote sensor. This home receiver can support up to three
remote sensors (only one is included). If it is looking for more than one
remote sensor, a " " icon will appear below the channel designator. Again,
to select a reading from just one remote sensor, press the "channel" button
to remove the scroll icon and ensure that the channel selected now
reads "1".
