GETTING STARTED

BATTERIES

Batteries are not supplied with this product. You will need
to purchase 2 x UM-3 (AA) 1.5V alkaline batteries for
the main unit, and 2 x UM-4 (AAA) 1.5V alkaline batteries
for the remote sensor.

Insert the 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.

Do not use rechargeable batteries.

NOTE

shows when batteries are low.

CHANGE SETTINGS

1. Press and hold MODE for 2 seconds to enter setting
mode.

2. Press UP or DOWN to change settings.

3. Press MODE to confirm.

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.

RMR613HGA lab test R3 2/18/04, 2:22 PM6

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.

SWITCH

Channel

OPTION

Channel 1 - 3. If you are using
more than one sensor, select a
different channel for each sensor.

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
Search for Sensor 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.

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 show the status.

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.

Signals from household devices such as

NOTE

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.

DESCRIPTION

Main unit is searching for
sensors.

At least 1 channel has
been found.

Channel 1 is selected
(number will change
depending on the sensor
you select)

The selected sensor cannot
be found. Search for the
sensor or check batteries.

CLOCK

This product can track the date and time for up to
2 locations (Clock with Offset Hour). The US Atomic
Clock in Boulder, Colorado automatically updates this
information unless you disable the feature. The 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.

NOTE

If the Atomic Clock signal is received and the
hour is incorrect, use the "hour offset" feature to adjust
it to to the right value. Please see "SET CLOCK" on
pg. 9 for instructions.

TURN ATOMIC CLOCK ON/OFF

Perform this step if you cannot receive Atomic Clock
signals. Press and hold DOWN for 2 seconds. Then,
manually set the clock following the “Set Clock”
instructions (below).

SWITCH CLOCK DISPLAY

Press MODE to toggle between Clock with Seconds,
Clock with Weekday and Calendar, and Clock with Offset
Hour display.

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. Press and hold MODE for 2 seconds. The Clock
Area will blink.

2. Select the offset hour, 12 / 24 hour format, hour,
minute, year, month, day, and language. Press UP
or DOWN to change the setting. Press MODE to
confirm.

The language options are (E) English,
