4. Insert the batteries strictly according to the polarities shown therein.
5. Replace the battery compartment door and secure its screws.
Replace the batteries when the low-battery indicator of the particular
channel lights up on the main unit. (Repeat the steps described in
section “BEFORE YOU BEGIN”)
Note that once a channel is assigned to a remote unit, you can only
change it by removing the batteries or resetting the unit.
BATTERY INSTALLATION: MAIN UNIT
The main unit uses two UM3 or "AA" size alkaline batteries.
To install them,
1. Slide open the battery compartment door.
2. Insert the batteries strictly according to the polarities shown therein.
3. Replace the battery compartment door.
LOW BATTERY WARNING
Replace the batteries when the low-battery indicator of the indoor
temperature display lights up. (Repeat the steps described in
section "BEFORE YOU BEGIN")
Respectively, for a remote sensor unit, the low-battery icon will
show when the channel is selected.
GETTING STARTED
Once batteries are in place for the remote units, they will start
transmitting temperature readings at 30-second intervals.
The main unit will also start searching for signals for about a
minute once batteries are installed. Upon successful reception, the
individual channel temperatures will be displayed on the top line
and the indoors temperature on the bottom line. The main unit will
automatically update its readings at about 30-second intervals.
