Insert batteries before first use, matching the polarity as
shown in the battery compartment. For best results,
install batteries in the remote sensor before the main
unit. Press RESET after each battery change.
NOTE
Do not use rechargeable batteries.

REMOTE SENSOR (THGR122NX)
This product is shipped with a THGR122NX Thermo/
Hygro Sensor that collects Temperature and Humidity
data. Data can be collected from up to 3 sensors.
Additional sensors sold separately.
SETUP SENSOR
Open the remote sensor battery compartment with a
small Phillips screwdriver.
1. Insert the batteries, matching the polarity as shown
in the battery compartment.
2. Set the channel. The switch is located in the
battery compartment.

3. Place the sensor near the main unit. Press RESET
on the sensor to initiate signal sending between the
sensor and the main unit. The reception icon on
the main unit will blink for approximately 3 minutes
while it is searching for the sensor. (Refer to the
Sensor Data Transmission section for more
information.)
4. Close the remote sensor battery compartment.
5. Secure the sensor in the desired location using the
wall mount or table stand.

OPTION
Channel 1 - 3. If you are using
more than one sensor, select a
different channel for each sensor.
RMR612HGA lab test R2 1/17/04, 4:58 PM6
Page 8
For best results:
• Insert the batteries and select the channel and
temperature unit before you mount the sensor.
• Place the sensor out of direct sunlight and
moisture.
• Do not place the sensor more than 30 meters
(98 feet) from the main (indoor) unit.
• Position the sensor so that it faces the main
(indoor) unit, minimizing obstructions such as
doors, walls, and furniture.
• Place the sensor in a location with a clear view
to the sky, away from metallic or electronic
objects.
• Position the sensor close to the main unit
during cold winter months as below-freezing
temperatures may affect battery performance
and signal transmission.
You may need to experiment with various locations to
get the best results.
DATA TRANSMISSION
Data is sent from the sensor(s) every 40 seconds.
The reception icon shown in the Temperature and
Humidity Areas shows the status.

DESCRIPTION
Main unit is searching for
sensors.
At least 1 channel has
been found.
Channel 1 is selected (the
number will change
depending on the sensor
you select).
--- shows in Temp/
Humidity Areas
The selected sensor cannot
be found. Search for the
sensor or check batteries.
SEARCH FOR SENSOR
To search for a sensor, press and hold MEM and
CHANNEL for 2 seconds.
If the sensor is still not found, check the
NOTE
batteries, obstructions, and remote unit location.
NOTE
Signals from household devices such as
doorbells, electronic garage doors, and home security
systems may cause temporary reception failure. This is
normal and does not affect general product performance.
The reception will resume once the interference ends.

CLOCK
This product shows the current time, time zone, and day
of week in English, Spanish, or French. The time is
automatically updated by the US Atomic Clock in
Boulder, Colorado unless you disable this feature.
Signals are collected by the main unit when it is within
1500 km (932 miles) of a signal.
Initial reception takes 2 - 10 minutes, and is initiated
when you first setup the unit, and whenever you press
RESET. Once complete, the reception icon will stop
blinking. The icon is shown in the Clock Area.
To force a manual search for Atomic Clock signals, press
and hold UP for 2 seconds. If no signal is found, check
the batteries.
TURN ATOMIC CLOCK ON/OFF
Perform this step if you cannot receive Atomic Clock
signals. Press and hold ZONE (located in the battery
compartment) for 2 seconds. Then, manually set the
clock following the “Set Clock” instructions (below).
The signal icon indicates that the Atomic Clock
feature is ON. No icon means that it is OFF.
SET CLOCK
You only need to do this if you have disabled the Atomic
Clock feature (for example, if you are too far from or
cannot receive a signal).
1. Open the battery compartment.
2. Press ZONE repeatedly to display the desired Time
Zone: (P) Pacific, (M) Mountain, (C) Central, or
(E) Eastern.
3. Close the battery compartment.
4. Press and hold MODE for 2 seconds. The Clock
Area will blink.
5. Select the hour, minute, year, month, day, and
language. Press UP or DOWN to change the
setting. Press MODE to confirm.
NOTE
The language options are (E) English,
(F) French, and (S) Spanish.
