USER’SMANUAL
INTRODUCTION
Congratulations on your purchase of the JTR-
168LR
Deluxe In/
Out Remote Thermometer.
The basic package comes with a main unit (the temperature
station) and a remote unit (the
therm0
sensor). The main unit can
support up to three remote units.
The JTR-168LR is easy to use. The main unit has a large display
for the outdoor temperatures, temperature variance for the last 12
hours and the indoor temperatures.
Additional features include ice warning and maximum/ minimum
temperatures for indoors and outdoors.
No wire installation is required between the main unit and the
remote units. As the JTR-168LR operates at
433MHz,
it can be
used in the U.S. and most places in Continental Europe.

HINTS
FOR
BEST
OPERATION
Assign different channels to different remote units.
Insert batteries for remote units before doing so for the main
unit.
Set the main unit and the remote thermo-sensor unit within an
effective range of 100 meters.
The effective range is vastly affected by the building materials
and how the units are positioned. Try different set-ups for best
results.
Though the remote units are weather proof, they should be placed
away from direct sunlight, rain or snow.

GETTING
STARTED
Once batteries are in place for the remote units, they will start trans-
mitting samplings roughly at 30-second intervals.
The main unit will also start receiving once batteries are installed.
The temperature of the selected channel will be displayed on the
top line and the indoor temperature on the bottom line. The main
unit -will automatically update its readings at 30-second intervals.
The temperature variance for the last 12 hours is automatically
scanned on
t
he trend chart.
CHANNEL 1
If no signals are received, blanks will be displayed. Press
[CHANNEL] and [MEMORY] simultaneously to enforce another
search. This is useful in synchronizing the transmission and recep-
tion of the remote and main units.
Repeat this step whenever you find discrepancies between the read-
ing 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 bottom line of the display.
Temperature readings, received from a remote sensor, are displayed
on the top line of the unit.
Press
[CHANNEL]
to change from one channel to the next.

If more than one remote sensor is being used, the unit can auto-
matically scan all three of the outdoor channels.
To use the automatic outdoor channel scanner function:
Press and hold [CHANNEL] for about 2 seconds. The unit will
begin a cycle of continuously rotating through the three channels.
Temperature readings from each site will be displayed for approxi-
mately 5 seconds.
To stop the automatic scanning function, press
[CHANNEL]
again.
The scanning cycles will stop.
The kinetic wave display on the channel icon indicates the status
of reception.
The unit is in searching mode.

If no readings are received from one particular channel for more
than two minutes, blanks will be displayed until further readings
are successfully searched. Check the remote unit is sound and
secure. You can wait for a little while or press
[CHANNEL]
and
[MEMORY]
simultaneously to enforce an immediate search. Of
course no reading will be shown if no remote unit is assigned to
that channel.
The JTR-168LR is capable of measuring temperatures within the
-5OOC
(-58°F) and
+7O”C
(+158”F)
range. If the temperature goes
above or below that, the display will show “HHH” or
“LLL”.
MAXIMUM
AND
MINIMUM
TEMPERATURES
The maximum and minimum recorded indoor temperatures and
those of each channel will be automatically stored in memory. To
display them,
1. Press
[CHANNEL]
to locate the desired channel.
2. Press [MEMORY] to rotate through the maximum [MAX],
minimum
[MINI
and current temperatures. The readings of the
indoor temperatures will also be displayed.
To clear the memory of a particular channel
1. Press
[CHANNEL]
to locate the desired channel.
2.
Press
[CLEAR],
the
MAX
and
MIN
memory for that channel
will be erased. Note it will also erase the memory for the indoor
temperatures. If you press [MEMORY] now, the maximum
and minimum temperatures will have the same values as the
current ones until different readings are recorded.

DISCONNECTED
SIGNALS
If without obvious reasons the display for a particular channel goes
blank, press [CHANNEL] and [MEMORY] to enforce an im-
mediate search. If that fails, check if the remote unit. of that chan-
nel is still in place. Make sure the transmission is within range and
path is clear of obstacles and interference.
HOW
TO
READ
THE
TEMPERATURE
TREND
CHART
The temperature variance for
CHANNEL 1
for the past 12 hours
is automatically scanned on the screen in six equal columns.
The variance is represented in rows of degrees C above or below
the current temperature at 0 Hr (current time) and 0°C (no
vari-
ante).

falls to between -2°C (28.4”F)
to
+3”C
(37.4”F)
a beeping alarm will sound; the ice warning icon
[
e
]
and current outdoor temperature will flash. The alarm will
sound every minute so long as the recorded temperature is within
alarm range. To stop the alarm, press any key or change the chan-
nel. Display features will continue to flash as a reminder that the
temperature remains within the ice warning range.
To deactivate the ice warning function, slide the
ICE WARNING
