3.3 Powering Up
Note: The power up sequence must be performed in the order shown in this section (remote
transmitter FIRST, Display Clock SECOND) to avoid the Clock synchronization time out.
The Transmitter:
1. Remove the battery door on the back of the transmitter and insert 2 new AA batteries,
according to the polarity information marked on the battery compartment, and replace the
battery door, as shown in Figure 2. Place the transmitter about 5 feet from the clock.
The Clock:

Version 1.3 ©Copyright 2016, Ambient LLC. All Rights Reserved. Page 6
1. Plug the AC adaptor into the DC jack of the clock.
2. Remove the battery door on the bottom of the clock and insert 3 new AA batteries, according
to the polarity information marked on the battery compartment, and replace the battery door.
3. Once the batteries are inserted, all of the LCD segments will light up briefly before entering
the sensor search mode.
4. Once the wireless transmitter has synced up to the clock, you can place the sensor outside.
Note: If no display is present after powering up the clock, press the reset button on the back of the
clock with an open ended paper clip or sharp tool.
3.4 Siting the Wireless Transmitter Outside
It is recommended you place the remote sensor in a shaded area.
Direct sunlight and radiant heat sources will result in inaccurate temperature readings. Although the
sensor is weatherproof, it is best to mount in a well-protected area, such as an eve. Do not place in
standing water or snow.
Wireless signals are impacted by distance, interference (other wireless devices, wireless phones,
wireless routers, TVs and computer monitors), and transmission barriers, such as walls. In general,
wireless signals will not penetrate solid metal and earth (down a hill, for example).
The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction
decreases the transmission range by the factor shown below.

press the SNOOZE/LIGHT button on the top of the clock. The alarm bell icon will keep flashing.
If the snooze function is turned on, the 4-step crescendo alarm will sound every five minutes. Press the
ALARM button to silence the alarm.
5.3 Projector and Backlight
5.3.1 Using the Projector and Backlight
Note: The projector and backlight are temporary when operating on batteries only, to save
battery life.
1. When the clock is powered by the battery:
Press the SNOOZE/LIGHT button to turn on the projector and backlight for 5 seconds
or press and hold the SNOOZE/LIGHT button for 4 seconds to turn on the projection for 30
minutes. Press the SNOOZE/LIGHT button again to turn off the projection.
2. When the clock is powered by theAC adapter:
Slide the PROJECTION ON/OFF switch to ON position, and the projection will be on all
of the time.
Slide the PROJECTION ON/OFF switch to OFF position, and the projection will be off all
of the time, unless you press the SNOOZE/LIGHT button as described in the previous
section.
Slide the LIGHT ON/OFF switch to ON position, and the backlight will be on all the time.
Slide the LIGHT ON/OFF switch to OFF position, and the backlight will be off all of the
time, unless you press the SNOOZE/LIGHT button as described in the previous section.

5.3.3 Adjusting Projector Focus
Adjust the focus of the projected data by rotating the focus knob on the projector.
5.3.4 Projector Temperature Display
The projector will scroll between the indoor and outdoor temperature. Each time you add an additional
channel sensor, the projector will add this sensor to the scroll feature. The scroll feature cannot be
disabled.
5.4 Barometric Pressure Display and Settings
5.4.1 Barometric Pressure Units of Measure
In normal time mode, press the BARO button to change barometric units of measure (hPa / inHg /
mmHg).
5.4.2 Absolute Pressure vs. Relative Pressure
Press and hold the BARO button for 2 seconds to enter barometric mode, and press the +/CHANNEL
button to switch between the relative and absolute pressure reading.
5.4.3 Relative Pressure Calibration
Please Reference Section 5.4.3.1 for details on the purpose of calibrating relative pressure, and how
to calibrate relative pressure in your area.
1. Press and hold the BARO button for 2 seconds to enter barometric mode. The icon BARO
will flash.
Make sure the REL Pressure is showing on the display. If ABS Pressure is showing, switch to
REL pressure per Section 5.4.2.
2. Press (do not hold) the BARO button again. The relative pressure will flash.
3. Press the +/CHANNEL to increase the relative pressure and -/MEM to decrease the relative
pressure.
4. Press (do not hold) the BARO button again to exit the relative pressure calibration mode, or
wait 60 seconds to time out.
Note: After calibration, the barograph will reset to 0 change (flat line across the graph).
5.4.3.1 Relative vs. Absolute Pressure and Calibration
The clock displays two different pressures: absolute (measured) and relative (corrected to sea-level).
To compare pressure conditions from one location to another, meteorologists correct pressure to
sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level corrected
relative pressure (the pressure your location would be at if located at sea-level) is generally higher
than your measured absolute pressure.
Thus, your absolute pressure may read 28.62 inHg (969 mb) at an altitude of 1000 feet (305 m), but
the relative pressure is 30.00 inHg (1016 mb).
