FEATURES
• The unit is an easy-to-use, state-of-the-art thermometer. The basic pack-
age comes with a main unit, which is the temperature receiver, and a
remote unit with an internal sensor and external sensor.
• The main unit has extra-large readouts for indoor temperatures and
temperatures transmitted by the remote unit. The main unit can support
up to three remote units.
• The main unit is capable of monitoring temperature changes of remote
sites. Set upper and lower temperature limits and the alarm will go off
when limits are exceeded. The maximum and minimum temperature of
different sites can also be retrieved quickly.
• No wire installation is required between the main and remote units. The
units operate at 433 MHz and can be used in the U.S. and most places
in Continental Europe.
Compliance
This product complies with standards and specifications of BZT, FCC and
article number 334 of PTT.

BEFORE BEGINNING
1. Assign different channels to different remote units.
2. Insert batteries for remote units before doing so for the main unit.
3. Place the main unit as close as possible to the remote unit, reset the
main unit after installing batteries. This will ensure easier synchroniza-
tion between the transmission and reception of signals.
4. Position the remote unit and main unit within effective transmission
range, which, in usual circumstances is 50 to 100 feet (15 to 30 meters).
Note: The effective range is significantly affected by building materials and
where the main and remote units are positioned. Try various setups for best
results.
Important: Though the remote units are weatherproof, they should be
placed away from direct sunlight, rain, or snow.
BATTERY AND CHANNEL INSTALLATION: REMOTE UNIT
The remote unit uses two AAA batteries. To install them:
1. Remove the screws on the battery compartment.
2. Select the channel number on the CHANNEL slide switch.
3. Select the temperature display unit on the °C/°F slide switch.
4. Insert the batteries strictly according to the polarities shown.
5. Replace the battery compartment door and secure its screws.
Replace the batteries when the low-battery indicator of the particular
channel lights up on the main unit. (Repeat the steps described in section,
“Before Beginning”.)
Note: Once a channel is assigned to a remote unit, it can only be changed
by removing the batteries or resetting the unit.
BATTERY INSTALLATION: MAIN UNIT
The main unit uses two AA batteries. To install them:
1. Slide open the battery compartment door.
2. Insert the batteries strictly according to the polarities shown.
3. Replace the battery compartment door.

Replace the batteries when the low-battery indicator of the indoor tempera-
ture lights up. (Repeat the steps described in section, “Before Beginning”.)
TWO SENSORS
Each remote module has two sensors. The internal (ambient) sensor is
located inside the case toward the bottom of the remote module. It is ideal
for monitoring air temperatures. It is automatically in use and in the circuit
when the external sensor is not plugged in.
The second sensor is the external one. Use it to monitor liquids, gases, and
semisolids. The external sensor is automatically in use when it is plugged
into the remote module. Plugging in the external sensor removes the
internal sensor from the circuit. The waterproof external sensor and 10-foot
cable perform accurately even when both are under water.
GETTING STARTED
Once batteries are in place for the remote units, they will start transmitting
temperature readings at 30-second intervals.
The main unit will also start searching for signals for about 2 minutes once
batteries are installed. Upon successful reception, the individual channel
temperatures will be displayed on the top line and the indoor temperature
on the bottom line. The main unit will automatically update its readings at
about 30-second intervals.
10
If no signals are received, blanks “- - -” will be displayed and the kinetic
wave icon will show “ ”. Press CHANNEL and MEM simultaneously to
force another search for 30 seconds. This is useful in synchronizing the
transmission and reception of the remote and main unit.
Repeat this step whenever you find discrepancies between the reading
shown on the main unit and that on the respective remote unit.
HOW TO CHECK REMOTE AND INDOOR TEMPERATURES
The indoor temperature is shown on the lower line of the display.
The remote readings are on the upper display. For the remote sites or
channels, press CHANNEL to go from one channel to another. The kinetic
wave display on the channel number indicates the reception of that particu-
lar channel is in good order.
If no readings are received from one particular channel for more than 2
minutes, blanks, “- - -” will be displayed until further readings are success-
fully searched. Verify the remote unit is sound and secure. Wait for a little
while or press CHANNEL and MEM simultaneously to force an immedi-
ate search. No reading will be shown if no remote unit is assigned to that
channel.
The temperature trend indicator on the screen shows the trend of readings
collected at that particular remote site. Three trends, rising, steady, and
falling, will be shown.
If the temperature goes above or below the temperature measuring range
of the main unit or the remote unit (stated in “Specifications” section), the
display will show “HHH” or “LLL”.
