1. The remote unit of that channel is still in place.
2. The batteries of both the remote unit and main unit. Replace as
necessary.
Note that hen the temperature falls belo freezing point, the
batteries of outdoor units ill freeze, lo ering their voltage supply
and the effective range.
3. The transmission is ithin range and path is clear of obstacles
and interference. Shorten the distance hen necessary.
TRANSMISSION COLLISION
Signals from other household devices, such as door bells, home
security systems and entry controls, may interfere ith those of this
product and cause temporarily reception failure. This is normal and
does not affect the general performance of the product. The
transmission and reception of temperature and humidity readings
ill resume once the interference recedes.

ABOUT RADIO RECEPTION
The BAR182HG is designed to automatically synchronize its
calendar clock once it is brought ithin range of the Frankfurt
DCF77 radio signal.
When the BAR182HG is ithin range, its radio-control mechanism
ill override all manual settings.
When the unit is receiving radio signal, the RADIO RECEPTION
signal ill start to blink. A complete reception generally takes
about 2 to 10 minutes, depending on the strength of the radio signal.
When the reception is complete, the RADIO RECEPTION signal
ill stop blinking. The strength of the reception ill remain until
the next scanning cycle backs place.
For better reception, place the clock a ay from metal objects and
electrical appliances to minimize interference.
