NOTICE
Avoid connectivity disruptions!
To avoid connectivity disruptions between the devices, consider the following points before starting
operation.
1. Place base station (receiver) and remote sensor (sender) together as close as possible.
2. Set up power supply for the base station and wait until the indoor temperature is displayed.
3. Set up power supply for the remote sensor.
4. Position the base station and the remote sensor within the effective transmission range.
5. Ensure that the base station and remote sensor are assigned to the same channel.
When changing batteries always change batteries in the main unit as well as all remote units and re-
place them in the correct order, so the remote connection can be re-established. If either of the
devices is mains-powered, the power supply must be disconnected for a short moment also for this
device when exchanging the batteries. If batteries are exchanged in only one of the devices (i.e. the
remote sensor) the signal can’t be received or can’t be received correctly.
Note, that the effective range is vastly affected by building materials and position of the main and re-
mote units. Due to external influences (various RC devices and other sources of interference), the
maximum distance can be greatly reduced. In such cases we suggest to position the main unit and the
remote sensor at other places. Sometimes all it takes is a relocation of one of these components of a
few inches!
8 Setting up power supply
Base unit
1. Remove the battery compartment cover.
2. Insert the batteries into the battery compartment. Ensure that the battery polarity (+/-) is correct.
3. Replace the battery compartment cover.
4. Wait until the indoor temperature is displayed on the base station.
Remote sensor
5. Remove the battery compartment cover.
6. Insert the batteries into the battery compartment. Ensure that the battery polarity (+/-) is correct.
7. Move the CH slide control to the position for the desired transmission channel (setting CH1, CH2
or CH3 with screen display).
8. Replace the battery compartment cover.
NOTICE! When operating one outdoor sensor, channel 1 is recommended as the default setting.
9 Manual time setting
1. Press the SET button for approx. 4 seconds to enter the time setting mode.
2. Digits to be set are flashing.
3. Press UP or DOWN button to change the value.
4. Press the SET button to confirm and switch to the next setting.
5. Sequence of the settings: Year > Month > Day > Language > 12-/24-hour mode > Hours > Minutes
