USER'S MANUAL

INTRODUCTION

Congratulations on your purchase of the RMR183/RMR183U Long-Range (60 meters) Multi-Channel In-Out Thermometer 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 sensor.

The main unit has a large display for indoor temperature, calendar clock and temperatures collected and transmitted by the remote unit. The main unit can support up to three remote units.

The main unit is capable of keeping track of the maximum and minimum temperature of different sites. No wire installation is required as the RMR183/RMR183U 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) (or Radio signal MSF-60 from Rugby, England for UK version).

You can also set the calendar clock manually when it is off range. Other features include five-language display, crescendo daily alarm and interchangeable display modes.

BEFORE YOU BEGIN

For best operation,

1. Assign different channels to different remote units.

2. Insert batteries for remote units before doing so for the main unit.

3. Place the main unit as close as possible next to the remote unit and reset the main unit after installing batteries. This will ensure easier synchronization between the transmission and reception of signals.

4. Position the remote unit and main unit within effective transmission range, which is 60 meters in open area.

Note that the effective range is vastly affected by the building materials and where the main and remote units are positioned. Try various set-ups for best result.

Though the remote units are weather proof, they should be placed away from direct sunlight, rain or snow.

Note:

1. Replace batteries when the low-battery indicator of a particular channel activates on the main unit.

2. Once a channel is assigned to a remote unit, it can only be changed by removing the batteries or resetting the unit.
