The Levenhuk Wezzer Teo TH40 is a thermohygrometer designed to provide accurate temperature and humidity readings both indoors and outdoors, along with a weather forecast. It consists of a base station and a wireless remote sensor.

Function Description

The base station displays the current indoor temperature and humidity, as well as the outdoor temperature and humidity received from the remote sensor. It also features a weather forecast, time display, calendar, and week display. The device can track temperature and humidity trends over 12 hours. An alarm function with a snooze option is included.

Usage Features

Getting Started:

Base Station: Power the base station by connecting the USB cable to a DC adapter (not included) and an AC power supply, or by inserting 3 AA batteries into the battery compartment (18). After power-up, the base station will search for outdoor units for 5 minutes. To manually set reception or switch channels (1, 2, or 3), press the CH button.

Sensor Connection:

Place the base station and remote sensor within effective transmission range. Ensure channels are assigned correctly.
Successful reception will display temperature and humidity; "—" indicates no signal. Check batteries and interference sources if no signal.
When changing batteries, replace them in the base unit first, then in all sensors, to re-establish connection. If using an adapter, briefly disconnect power during battery replacement.
The effective range may vary due to unit position and interference from other devices. Moving the units slightly can improve signal reception.
The sensor is weather-resistant but should not be placed in direct sunlight, rain, or snow.
