Thermometer.
The basic package comes with a main unit and a remote sensor.
The main unit can support up to three remote sensors.
The MTR101 is very easy to use. No wire installation is
required between the main unit and the remote units. As the
MTR101 operates at 433MHz, it can be used in the U.S. and
most places in Continental Europe.

• Try different set-ups for best transmission and reception.
• Position the remote units away from direct sunlight, rain
or snow.
BATTERYAND CHANNEL
INSTALLATION: REMOTE UNIT
1. Remove the screws on the battery compartment.
2. Select the channel number on the CHANNEL slide switch.
3. Install 2 alkaline batteries (UM-4 or “AAA” size 1.5V)
strictly according to the polarities shown.
4. Replace the battery compartment door and secure its
screws.
Note that once a channel is assigned to a remote unit, you can
only change it by removing the batteries or resetting the unit.
BATTERY INSTALLATION: MAIN UNIT
1. Slide open the battery compartment door.

To start an automatic scan on all channels, press and hold
CHANNEL for two seconds. The main unit will scan from
one channel to another and back. The reading for individual
channel will be displayed for five seconds. Press any key to
end the automatic scan.
The MTR101 is capable of measuring temperatures within the
-50°C (-58°F) and +70°C (+158°F) range. If the temperature
goes above or below that, the display will show "HHH" or
"LLL".
MAXIMUM AND MINIMUM
TEMPERATURES
Themaximumandminimumrecordedindoortemperaturesand
those of each channel will be automatically stored in memory.
To display them,
1. Press [CHANNEL] to locate the desired channel.
2. Press[MEM] repeatedly to display the current, maximum
(MAX) and minimum (MIN) temperatures. The readings
of the indoor temperatures will also be displayed.
GETTING STARTED
Once batteries are in place for the remote units, they will start
transmitting 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 main display and the indoor temperature on
the secondary display.The main unit will automatically update
its readings at 30-second intervals.
If no signals are received, blanks will be displayed. Press
CHANNELandMEMsimultaneouslytoenforceanimmediate
search. This is useful in synchronizing the transmission and
reception of the remote and main units.
INDOOR AND OUTDOOR
TEMPERATURES
The indoor temperature is shown on the secondary display.
As for the remote sites or channels, press CHANNEL
repeatedly to go from one channel to another. The kinetic wave
display on the channel number indicates the reception of that
particular channel is in good order.

To clear the memory of a particular channel,
1. Press [CHANNEL] to locate the desired channel.
2. Press [CLEAR]. Note it will also erase the memory for
the indoor temperatures. If you press MEM 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 [MEM] to enforce an
immediate search. If that fails, check if the remote unit of that
channel is still in place. Make sure the transmission is within
rangeandpathisclearofobstaclesandinterference.Noreading
will be shown if no remote unit is assigned to that channel.
LOW BATTERY WARNING
When it is time to replace batteries, the respective low-battery
indicator will show up when the respective channel is selected.
The battery level of the main unit will be shown on the indoor
temperature when it is running low.
HOW TO USE THE TABLE STAND
OR WALL MOUNTING
Turn the table stand knob out to place the main unit on a flat
surface. Or you can hide the stand and mount the unit on a
wall using the recessed hole.
As for the remote unit, use the providedVelcro ® tape to secure
it in place.
