Operating Range of Batteries Severe cold (below -4º F/-20º C) can cause alkaline
batteries to freeze and function improperly. Use lithium
batteries in extremely low temperature conditions to
ensure continued operation for wireless sensors placed
outdoors.
NOTE: The main unit is intended for indoor use only. Choose a dry location away from dust,
dirt, mold, smoke and avoid temperature extremes. Do not drop the clock. It is a sensitive
electronic device and not designed to withstand high impact blows of any kind.
Install 2 “AA” batteries into the main unit FIRST. The clock immediately displays the correct
time for the eastern (U.S.) time zone. Next, Install 2 “AA” batteries (lithium is recommended
for areas where the temperature may fall below -4ºF) into the wireless sensor.
To set the time zone, press and hold the “CH./SET” button for 4 seconds. The currently
selected time zone will flash below the time display. Press the “+” button to cycle through
the time zone options (see below for more information on timezones). When you have
selected the desired timezone, press the “CH./SET” button to confirm and move on to
selecting your Daylight Saving Time (DST) setting. Press the “+” button to cycle through
the DST setting options (see below for more information on DST options).

Internal Batteries: (2 x L1142)
We suggest replacement of the internal batteries every five years if the clock has been in
continuous use over that time. However, if the clock has not been plugged in and powered
for long periods of time, we recommend replacing the internal batteries more frequently –
once a year.
NOTE: the internal batteries provide power for the internal calendar. The internal batteries
will NOT power the alarm functions in the event of a power outage.
