Manual for wireless thermometer
Overview
This thermometer allows you to view temperatures at a base receiver sent
by up to three external transmitters (at the frequency 433,92 MHz). This
unit ships with a single transmitter, but additional transmitters may be
purchased at local retailers. The transmission range is up to 30 metres
(assuming optimal conditions), and the base receiver features additional
functions like a clock and a selector for °C or °F. You may view maximum
and minimum temperatures including the ability to set alerts for high
and low temperatures.
Contents of packaging
Your box should have the following contents:
- a receiving unit (Thermometer)
- a sensor (transmitter) with external temperature probe for fluids
- a plastic foot for tabletop use
Batteries
We strongly suggest the use of alkali batteries.
Receiving Unit: 2 x AAA Batteries (Micro)
Sensor (each): 2 x AAA Batteries (Micro)
Suggestions for optimal placement of the sensors
1. Like every thermometer you should not place the sensor in direct sun
light.
2. Never immerse the sensor and the receiving unit into water or expose
it to heavy rain. For measuring the temperature of fluids you need the
special temperature probe added in the box.
3. Bright backgrounds reflect temperatures while dark backgrounds absorb
them. The placement of the sensor in front of a dark background may
adversely affect temperature readings.
4. Do not place the sensor near the floor. Best results are achieved at
a height of about 1.5 metres.
5. You will achieve the best communications between the receiving unit
and sensor if you reduce the number of obstacles between them.
6. Please avoid using the sensor or the base station near computers, microwaves, wireless phones, net
adaptors or other units. They might disturb the transmission.
