BATTERY INSTALLATION
REMOTE SENSOR
NOTE: Install the batteries; select temperature
unit C
°
or F
°
before mounting the remote sensor
1. Remove the screws from the battery compartment with a
small Phillips screwdriver.
2. Install 2 “AA” size alkaline batteries (not included) matching
the polarities shown in the battery compartment.
3. Replace the battery compartment door and secure the screws.
4. Secure remote sensor in the desired location.
MAIN UNIT
1. Open the battery compartment door.
2. Install 2 batteries (UM-3 or “AA” size 1.5V) matching
the polarity as shown in the battery compartment.
3. Replace the battery compartment door.
LOW BATTERY WARNING
A low-battery indicator [ ] will appear on the indoor or
remote temperature reading line of the main unit warning that
the corresponding unit batteries need replacement.
HOW TO USE THE TABLE STAND
The main unit has a removable table stand that supports it on
the flat surface. Attach table stand to the bottom of the main
unit in the slots provided. The unit can also be mounted on the
wall using the recessed screw hole. The table stand must be
removed prior to mounting. The remote sensor can be similarly
mounted or placed on a flat surface.
GETTING STARTED
After batteries are installed; remote sensor will transmit
temperature readings at 45 second intervals.
The main unit may take up to two minutes to receive the initial
readings. Upon successful reception, remote temperature will
appear on the top line of the main unit’s display. The main unit
will automatically update readings at 45-second intervals.
If no signals received from the remote sensor within two
minutes, dashes [ ] will be displayed. Press and hold
DOWN
( ) button on the main unit for two seconds to
initiate another signal search.
WWVB RADIO CONTROLLED TIME
The NIST (National Institute of Standards and Technology)
radio station (WWVB) is located in Ft. Collins, Colorado. It
transmits an exact time signal continuously throughout the
most of the continental United States at 60 KHz frequency.
The Wireless Thermometer can receive this WWVB signal
through the internal antenna from up to 2,000 miles away.
Due to the nature of the Earth’s ionosphere, reception can be
limited during the daylight hours. The radio controlled clock
will search for an alternate station that receives the atomic time
signal from the NIST Atomic clock in Boulder, Colorado.
The WWVB tower icon on the main unit’s display will flash
indicating a radio signal reception from the WWVB station.
If the tower icon is not fully lit, or if the time and date are not
set automatically, please consider the following:
• During night-time hours, atmospheric disturbances are
typically less severe and radio signal reception may improve.
A single daily reception is sufficient enough to keep the
clock accuracy within 1 second.
The indoor temperature with the icon
IN
is located below the
remote temperature information line.
NOTE: If the indoor or remote temperature goes above or
below operating range stated in specifications, the main unit’s
display will show dashes [ ].
The unit is in searching mode.
Temperature readings are
securely registered.
No signals detected.

CHECKING REMOTE AND INDOOR TEMPERATURES
The remote temperature information line is located on the top
of the main unit’s display.
The wave icon is located above the remote channel number
and indicates the reception status from the remote sensor.
There are three following types of the reception status that
may be displayed.
