GETTING STARTED

POWER

Insert batteries before ﬁrst use, matching the polarity

(+ and -).

NOTE Install batteries in the remote sensor before the

main unit. Press RESET after each battery change. 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. Slide open the battery door.

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

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 meters (100

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.

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

• MSF-60 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 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.

a few precautions:

• Do not immerse the unit in water. If you spill liquid

over it, dry it immediately with a soft, lint-free cloth.

• Do not clean the unit with abrasive or corrosive

materials.

• Do not subject the unit to excessive force, shock,

dust, temperature or humidity, which may result in

malfunction, shorter electronic life span, damaged

battery and distorted parts.

If the channel 1 sensor falls between 3°C to -2°C (37°F

to 28°F), ﬂashes to warn you that the temperature is

approaching freezing.

NOTE The warning will automatically stop if the

temperature goes outside the ice-warning range.
