Optimum Viewing Angle; Installing The Remote Sensor - BIOS WEATHER 339BC Manual

3. Using other electrical products such as headphones or speakers operating on the same
frequency (433MHz) may prevent correct signal transmission and reception.
4. Neighbours 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 50 metres (164 feet) 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.
3.0 Mounting
CAUTION: Great care must be taken when mounting the components. The manufacturer/
supplier cannot be held liable for personal or property damage when setting up the
components. Please use caution when choosing a mounting point.
Prior to drilling mounting holes and permanently affixing any of the units, please ensure the
following points are considered:
1. Signal from the remote sensor can be received by the monitor at mounting point.
2. Make sure the remote sensor is easily accessible. You will have to periodically replace batteries.
3.1 Monitor
The monitor can be placed on any flat surface.

3.2 Optimum Viewing Angle

You must always keep in mind that the LCD screen is constructed with an "optimum viewing
angle". Your eye should be at a 45° angle to view the LCD screen clearly.

3.3 Installing the Remote Sensor

To prevent temperature interference, place the remote sensor away from direct sunlight, air
conditioning, and heater vents. The remote sensor is designed to be splash proof; never immerse
into water or expose to heavy rain.
NOTE: The temperature signal travels in a straight line from the remote sensor to the monitor.
The signal will not curve around an object. Please take this into consideration when mounting the
remote sensor.
