Optional Battery Operation
1. Remove battery cover: Slide tab to the right and pull out to remove battery cover.

Do Not Mix Old and New Batteries
Do Not Mix Alkaline, Lithium, Standard, or Rechargeable Batteries
If the Projection Alarm does not display indoor temperature after 60 seconds, remove adapter and
batteries, and wait for at least 60 seconds before repeating the setup process.
IMPORTANT: When operating on A/C power, the backlight, projection and USB charging port will turn off
while the Projection Alarm searches for the WWVB signal, to avoid interference. The backlight and
projection will return after the 2-10 minute search. Then the USB charging port will resume working.

Install Batteries in the Outdoor Transmitter

1. Slide the battery cover down, then lift off the front of the transmitter.
Note: Be careful not to break the tabs on the battery cover.
2. Insert two fresh AA batteries into the transmitter. Observe the correct polarity (see markings
inside battery compartment).
3. Keep transmitter 5-10 ft. from the Projection Alarm during setup.
4. After 15 minutes, if the outdoor temperature shows on the display, you can move the
outdoor transmitter outside to a shaded location within range of the Projection Alarm.
Troubleshooting
If the Projection Alarm does not display the outdoor temperature after 3 minutes, remove the A/C
power adapter and all batteries from both units and start the setup process again.
If the outdoor temperature does not show up after a second attempt, please slide open the battery
cover of the outdoor transmitter to reveal the TX button. Press the TX button for 3 seconds to send a
wireless signal to the Projection Alarm.
Hold the +/TEMP button for 5 seconds so the clock will search for the sensor.
For optimal 433 MHz signal reception, the outdoor transmitter should be placed within 200 feet (60
meters) from the Projection Alarm.
