GETTING STARTED

BATTERIES

Insert batteries before ﬁrst 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.

To set up the sensor:

1. Remove the screws from the battery door.

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

P/N:086L004344-058 REV 1

5/94

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.

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

channel for each sensor.

4. Place the sensor near the main unit. Press RESET

on the sensor.

5. Simultaneously press CHANNEL and MEM on the

main unit to initiate signal sending between the

sensor and main unit.

6. Close the battery door and secure the screws.

7. Place the sensor in the desired location using the

table stand or wall mount.

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 signiﬁcant 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).

The sensor cannot be found.

Search for the sensor or

check batteries

A channel has been found

and sensor signal is being

received

Main unit is searching

for the sensor(s)

To search for a sensor:

Simultaneously, press and hold MEM and CHANNEL

for 2 seconds.

NOTE If the sensor is still not found, check the batteries,

obstructions, and remote unit location.

CLOCK

CLOCK RECEPTION

This product is designed to synchronize its date and time

automatically once it is within range of :

• DCF-77 generated from Frankfurt, Germany for

Central Europe.

• MSF-60 generated from Anthorn, England.

RECEPTION SIGNAL

To enable and force a signal search:

Press and hold for 2 seconds.

To disable the signal reception:

Press and hold for 2 seconds.

STRONG SIGNAL WEAK SIGNAL NO SIGNAL

SET CLOCK

If the clock signal reception is enabled and a signal is

being received the clock does not need to be manually

set.

1. Press and hold MODE for 2 seconds.

2. Press or to change the settings.

Clock signal reception indicator:

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 ﬁrst 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.

• Press any key except SNOOZE to turn the alarm off

and activate it again after 24 hours.

BAROMETER

Barometer readings from the past 24 hours are stored by

the main unit and used to provide weather forecast.

To select barometer measurement unit:

Press PRESSURE to toggle between mb and inHg.

3. Press MODE to conﬁrm.

4. The settings order is: time zone offset, hour, minute,

year, month, day and language.

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

(D), French (F), Italian (I), and Spanish (S).

Press MODE to choose between the clock with seconds

and clock with weekday display modes.

WEATHER FORECAST
