INTRODUCTION
Congratulations on your purchase of the RMR132HG
Multi-Channel In-Out Thermo-Hygrometer with 433MHz cable
free sensor and radio-controlled calendar clock.
The basic package comes with a main unit, which is the
temperature and calendar clock station, and a remote unit, the
Thermo-Hygrometer sensor.
The main unit has large read-outs for indoors temperature and
humidity, calendar clock, temperatures and relative humidity
collected and transmitted by the remote unit. The main unit can
support up to 3remote units.
The main unit is capable of keeping track of the maximum and
minimum recordings of different sites. And no wire installation is
required and the RMR132HG operates at 433MHz.
As for the calendar clock, it is radio-controlled. It automatically
synchronizes its current time and date when it is brought within an
approximate 1500km radius of the radio signal generated from
Frankfurt, Germany (DCF77).
You can also set the calendar clock manually when it is off range.

THE RESET BUTTON
This button is only used when the unit is operating in an unfavorable
way or malfunctioning. Use a blunt stylus to hold down the button.
All settings will return to their default values.
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/CHANNEL &[MEMORY] for 2-seconds
to enforce a 3-minute search.
This is useful in synchronizing the transmission and reception of
the remote and main units.
Repeat this step whenever you find discrepancies between the
reading shown on the main unit and that on the respective remote
unit.
