Getting started
Base station
- Open the battery compartment cover (10) and insert 2 batteries according to the correct polarity. Close the cover.
- Wait until the indoor temperature is displayed on the base station.
Sensor
- Open the battery compartment cover (8). The sensor should be operated on channel 1.
- Insert 2 batteries according to the correct polarity. Close the cover.
- To re-establish the sensor connection manually, press RESET using a pin.
Sensor connection
-
Place the base station and the remote sensor within the effective transmission range.
Ensure that the channels are assigned after you set up the power supply for the base station and all the sensors. -
If the reception is successful, the display will show the temperature of the respective outdoor sensor. If the values are not received from a channel, “—” appears on the display. Check the batteries and try it again. Check if there is any source of interference.
-
When changing batteries, replace the batteries first in the base unit, and then in all the sensors, to re-establish the connection. If an adapter supplies power to any of the devices, briefly disconnect the power to that device when replacing the batteries. If you change the batteries only in one of the devices (for example, in the sensor), the signal may not be received correctly.
-
The effective range may differ depending on the unit’s position. Due to interference (various remote control devices, etc.), the maximum distance between the base unit and the sensor may be significantly reduced. In such cases, we suggest moving the base unit and sensor a little. Sometimes it is enough to move one of these units a few inches!
NOTE! Although the sensor is weather-resistant, never place it in direct sunlight or in the rain or snow.
Time setting
Press SET and hold it for 3 seconds. The digits that are to be set are
flashing. Press MEM to change the value, and then press SET to continue.
The setting order: 12/24h > Hours > Minutes.
Temperature units
Press SET to switch between ℃ and ℉.
History record
Press MEM to display the MAX. and MIN. temperature values.
Hold MEM to clear the MAX. and MIN. IN/OUT temperature record.
