TO INSTALL AND REPLACE BATTERIES IN THE

WIRELESS THERMO-HYGROMETER

The wireless thermo-hygrometer uses 2 x AAA, IEC LR3, 1.5V

batteries. To install and replace the batteries, please follow the

steps below:

1. Insert finger or other solid object

in the space at the bottom

center of the battery

compartment and lift up to

remove the cover.

2. Insert batteries observing the

correct polarity (see marking).

3. Replace compartment cover.

Battery replacement

•

Replace the batteries when the battery symbol of the

Wireless thermo-hygrometer appears above the indoor

humidity display.

•

When the batteries of the transmitter are used up, the low

battery icon appears above the outdoor humidity display.

Note:

In the event of changing batteries in any of the units, all units

need to be reset by following the setting up procedures. This is

due to a random security code assigned by the transmitter at

start-up. This code must be received and stored by the

Wireless thermo-hygrometer in the first 3 minutes of power

being supplied to the transmitter.

SETTING UP

1. First, insert the batteries in the transmitter (see “To

install and replace batteries in the thermo-hygro

transmitter” above).

2. Within 2 minutes of powering up the transmitter, insert

the batteries in the wireless thermo-hygrometer (see “To

install and replace batteries in the wireless thermo-

hygrometer” above). Once the batteries are in place, all

segments of the LCD will light up briefly. Following the

indoor temperature/humidity will be displayed. If this

information is not displayed on the LCD after 60 seconds,
