Before You Begin

4.0 Set up procedure:

1. Insert batteries into the monitor ﬁrst and then press the RESET button once.

2. Place the monitor as close as possible next to the remote sensor and insert the

batteries into the remote sensor and press the RESET button.

3. Position the monitor and remote sensor within effective transmission range, which

in usual circumstances is 30 to 45 meters. The range is affected by the building

materials and where the monitor and remote sensor are positioned; try various

locations for the best results.

Note: The remote sensor should be placed in a shaded area for accurate readings.

4.1 Getting Started

Once the remote sensor has been powered up (or the RESET button has been

pressed), the transmission signal is immediately sent to the monitor. The monitor will

attempt to search for the signal for 5 minutes.

Once the signal is received, the dashes (--.-°F) on the monitor will change to the

current outdoor temperature. If after 5 minutes the screen does not change to show

the outdoor temperature, press the RE-SYNC button on the monitor. The monitor will

now attempt to search for the signal for another 6 minutes.

5.0 Troubleshooting

Press the RESET button at any time your display shows dashes (--.-°F) and/or to

ensure that the remote sensor is in direct line to the monitor.

If the outdoor temperature cannot be received, check:

1. The distance between the monitor or remote sensor should be at least 0.9 to 1.2

meters away from any interfering sources such as computer monitors or TV sets.

2. Avoid placing the monitor onto or in the immediate proximity of metal window

frames.

3. Using other electrical products such as headphones or speakers operating on

the same signal frequency (433MHz) may prevent correct signal transmission and

reception.

4. Neighbors using electrical devices operating on the 433MHz signal frequency can

also cause interference.

5. Signals from other household devices, such as door bells and home security

systems, may temporarily interfere with the units and cause reception failure. The

transmission and reception of temperature reading will resume once the

interference has stopped.

The maximum transmission range is 45 meters from the remote sensor to the

monitor (in open space). However, this depends on the surrounding environment and

interference levels. The temperature signal travels in a straight line from the remote

sensor to the monitor. The signal will not curve around an object. If no reception is

possible, despite the observation of these factors, all units will have to be reset.

Note: To reset unit please see Set up Procedure. (See section 1.0).
