INTRODUCTION

Congratulations on your purchase of the Multi-Channel In-Out
Thermometer / Hygrometer (BHGR618) with a 433MHz cable­free thermo-hygro sensor.

Enclosed with this package is one (1) main display unit and
one (1) cable-free remote thermo-hygro sensor unit.

The main unit has an LCD that shows recordings for indoor
and outdoor temperatures, humidity, maximum and minimum
recordings. The unit supports up to three 433MHz remote
thermo-sensors or thermo-hygro sensors.

No wire installation is required between the main and remote

“AAA” size alkaline batteries.

Follow these steps to install / replace batteries:

1. Loosen the screw on the battery door.

2. Select the channel number on the CHANNEL slide switch.

3. Select the temperature display unit on the °C/°F slide switch.

4. Insert the batteries strictly according to the polarities shown
therein.

5. Replace the battery door and secure its screws.

Note that once a channel is assigned to a remote unit, you
can only change it by removing the batteries or resetting
the unit.

BEFORE YOU BEGIN

To ensure proper functioning of the BHGR618 follow this setup
procedure.

For best operation:

1. Assign different channels to different remote units.

2. Insert batteries in remote units before doing so for the main
unit (see instructions for battery installation).

3. Place the main unit as close as possible to the remote unit,
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, in usual circumstances, is 65 to
100 feet.

BATTERY INSTALLATION: MAIN UNIT

The main unit uses two (2) UM-3 or “AA” size alkaline batteries.

Follow these steps to install / replace batteries:

1. Remove the screw to open the battery door.

2. Insert the batteries strictly according to the polarities shown
therein.

3. Select the temperature display unit on the °C / °F slide switch.

4. Replace the battery door and fasten the screw. Replace the
batteries when the low-battery indicator of the indoor
temperature lights up (Repeat the steps described in section
"BEFORE YOU BEGIN")
