BATTERY AND CHANNEL INSTALLATION:
REMOTE UNIT
The remote thermo-hygro sensor unit uses two (2) UM-3 or
“AA” size batteries.
Follow these steps to install / replace batteries:
1. Remove the screws on the battery compartment.
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 compartment door and secure its screws.
Replace the batteries when the low-battery indicator of the par-
ticular channel lights up on the main unit.
Note: Once a channel is assigned to a remote unit, you can only
change it by removing the batteries or resetting the unit.
Standard Alkaline batteries contain signifcant amounts of water.
Because of this they will freeze in low temperatures of
approximately 10°F (-12°C). Disposable Lithium batteries have
a much lower threshold for temperature with an estimated freezing
range of below -40°F (-40°C). The Liquid Crystal Display in
outdoor thermometers will remain operational to -20°F (-28°C)
with adequate power.
Wireless ranges can be impacted by a variety of factors such as
extremely cold temperatures. Extreme cold may temporarily reduce
the effective range between the sensor and the base station. If the
unit's performance fails due to low temperature, the unit will
resume proper functioning as the temperature rises to within the
normal temperature range (i.e no permanent damage will occur
to the unit due to low temperatures).
LCD AND KEY-PANEL BACKLIGHT
For easy viewing in the dark this unit is featured with backlight
function on the LCD display as well as on the front key-panel.
The unit is designed such that you can conveniently use the
backlight feature irrespective of whether the unit is wall-mounted
or free standing on the table.
