GETTING STARTED

BATTERIES

Insert batteries before ﬁ rst use, matching the polarity (+

and -). Press

RESET

after each battery change.

indicates main unit batteries are low.

NOTE

Do not use rechargeable batteries. We

recommend that you use alkaline batteries with this

product for longer usage and lithium batteries in

temperatures below freezing.

REMOTE SENSOR

The sensor collects temperature readings approx. every

40 seconds and sends them to the main unit. The main

unit can collect data from up to 3 sensors.

RMR683HG_M_EN_RC3.indd 5 2006.5.26 11:11:08 AM

To set up the sensor:

1. Slide open the battery door.

2. Insert the batteries, matching the polarity (+ / -).

Press RESET after each battery change

3. Select a channel. Make sure you use a different

channel for each sensor.

4. Close the battery compartment.

5. Secure the sensor in the desired location using the

wall mount or table stand.

For best results:

• Place the sensor out of direct sunlight and

moisture.

• Do not place the sensor more than 30 m (100 ft) 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.

The transmission range may vary depending on many

factors. You may need to experiment with various

locations to get the best results.

Standard Alkaline batteries contain signiﬁ cant amounts of

water. Because of this they will freeze in low temperatures

of approximately -12°C (10°F). Disposable Lithium batteries

have a much lower threshold for temperature with an

estimated freezing range of below -30°C (-22°F).

Wireless ranges can be impacted by a variety of factors

such as extremely cold temperatures. Extreme cold

may temporarily reduce the effective range between the

sensor and the base station. If the unit’s performance

fails due to low temperature, the unit will resume proper

functioning as the temperature rises to within the normal

temperature range (i.e. no permanent damage will occur

to the unit due to low temperatures).

CLOCK RECEPTION

This product is designed to synchronize its date and time

automatically once it is within range of :

• DCF77 generated from Frankfurt, Germany for

Central Europe.

• MSF60

generated from Rugby, England.

The clock collects the radio signals whenever it is within

1500 km (932 miles) of a signal.

NOTE

Slide the

EU / UK

switch to appropriate position

for your location. Repeat each time you reset the unit.

NOTE

Initial reception takes 2-10 minutes for ﬁ rst set

up or when

RESET

is pressed. Once complete, the

reception icon will stop blinking. If the signal is weak, it

can take up to 24 hours to get a valid signal.

NOTE

The time zone offset can be used to set the

clock up to + / - 9 hours from the received clock signal

time. If you have disabled the clock signal reception (i.e.

manually setting the clock), do not set a value for time

zone offset.

NOTE

The language options are English (E), German
