GETTING STARTED
Once batteries are placed in a given remote sensor unit, it will start
transmitting information at 40-second intervals.
Also, for approximately a 3-minute duration, the main unit will
automatically search for signals once batteries are installed. Upon
successful reception, the individual channel temperature reading
will be displayed on the top line and the respective humidity reading
on the bottom line. The main unit will automatically update its
readings at about 40-second intervals.
If no signals are received, blanks “ --- ” will be displayed and the
kinetic wave icon will not show.
To force a signal search:
• Press and hold IN/REMOTE for 2-seconds to enforce a
3-minute search.
This is useful in synchronizing the transmission and reception of the

2. The batteries of both the remote unit and main unit. Replace as
necessary.
Note that when the temperature falls below freezing point, the
batteries of outdoor units will freeze, lowering their voltage
supply and the effective range.
Note: If a second limit is passed while an alarm is active, the
first alarm will complete its 1-minute cycle and the alarm will
continue to activate for a second minute to indicate that a
second limit has been surpassed.
3. The transmission is within range and path is clear of obstacles and
interference. Shorten the distance when necessary.
