2.2 Indoor / Outdoor Thermo-Hygrometer Setup
Note: To avoid permanent damage, please take note of the battery polarity before inserting the
batteries.
1. Remove the battery door on the back of the sensor (Figure 1a).
2. Insert 2 x AA batteries
3. After inserting the batteries, the remote sensor will display temperature and humidity on the
display, as shown in Figure 1b.
4. Close the battery door.
Note: We recommend lithium batteries for cold weather climates, but alkaline batteries are sufficient
for most climates. We do not recommend rechargeable batteries. They have lower voltages, do not
operate well at wide temperature ranges, and do not last as long, resulting in poorer reception.
Note: The outdoor humidity is displayed on the remote sensor, on the Internet (AmbientWeather.net
and Wunderground.com) but not displayed on the receiver to reduce the cost of the console.

Figure 1
2.3 Sensor Placement
It is recommended you mount the remote sensor outside on a north facing wall, in a shaded area, at a
height at or above the receiver. If a north facing wall is not possible, choose a shaded area, under an
eve.
Direct sunlight and radiant heat sources will result in inaccurate temperature readings. Although the
sensor is weatherproof, it is best to mount in a well-protected area, such as an eve.
1. Use a screw or nail to affix the remote sensor to the wall, as shown in Figure 2.
2. Hang the remote sensor up on string or zip tie, as shown in Figure 3.
Note: Make sure the sensor is mounted vertically and not lying down on a flat surface. This will
insure optimum reception. Wireless signals are impacted by distance, interference (other weather
stations, wireless phones, wireless routers, TVs and computer monitors), and transmission barriers,
such as walls. In general, wireless signals will not penetrate solid metal and earth (down a hill, for
example).

2.4 Best Practices for Wireless Communication
Wireless communication is susceptible to interference, distance, walls and metal barriers. We
recommend the following best practices for trouble free wireless communication.
1. Electro-Magnetic Interference (EMI). Keep the console several feet away from computer
monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 915 MHz devices and
communication is intermittent, try turning off these other devices for troubleshooting
purposes. You may need to relocate the transmitters or receivers to avoid intermittent
communication.
3. Line of Sight Rating. This device is rated at 300 feet line of sight (no interference, barriers or
walls) but typically you will get 100 feet maximum under most real-world installations,
which include passing through barriers or walls.
4. Metal Barriers. Radio frequency will not pass through metal barriers such as aluminum
siding. If you have metal siding, align the remote and console through a window to get a clear
line of sight.
The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction
decreases the transmission range by the factor shown below.
Medium
RF Signal Strength Reduction
Glass (untreated)
5-15%
Plastics
10-15%
Wood
10-40%
Brick
10-40%
Concrete

Metal

2.5 Display Console
(1) Connect the display console power jack to AC power adapter with the included power adapter,
as shown in Figure 4a.
(2) Remove the battery door on the back of the console, and insert 2xAAA batteries per Figure
4b.
(3) Wait several minutes for the remote sensor to synchronize with the display console. Make
sure the remote sensor is powered up and about 5 to 10 feet away while waiting for
synchronization. The remote search icon will be present while searching.
Do not touch any buttons until the remote sensor reports in, otherwise the remote sensor
search mode will be terminated and the search icon will turn off. When the remote sensor has
been received, the console will automatically switch to the normal mode, and all further
settings can be performed.

2.6 Display Console Probe
The display console includes a 90 cm (about 3 feet) dry probe to accurately measure air temperature,
since the console generates heat. The probe should not be touching any surface to accurately measure
air temperature.
