D. EL BACKLIGHT
1. The projection alarm has an EL backlight designed for night-viewing. This will light up
for 4 seconds whenever the snooze button is pressed.
2. The EL backlight cannot be turned on constantly; this would drain the batteries.
E. INDOOR TEMPERATURE
1. The projection alarm measures indoor temperature with an internal sensor.
2. This temperature is displayed in °F.
3. The indoor temperature will take time to adjust to the surrounding temperature as the
sensor is inside the case.
4. If the remote temperature is placed next to the projection alarm, more often than not
the temperature will not be exact with one another. This is not a defect, but simply
reflects the difference in measuring methods. The remote temperature is designed for
changing temperature at a wide range.
F. INDOOR HUMIDITY
1. The projection alarm measures indoor humidity with an internal sensor.
2. This humidity is displayed as a percentage (%).
3. The indoor humidity will take time to adjust to the surrounding humidity as the sensor
is inside the case.
G. REMOTE TEMPERATURE
1. The projection alarm comes with a remote temperature sensor. When set up properly,
the projection alarm will receive and display the remote temperature.
2. It is important to power up the sensor first, then the projection alarm. If batteries are
removed in the remote, the projection alarm MUST be re-set by removing power
sources and re-starting.
3. The remote temperature is measured within the remote temperature and transmitted
to the projection alarm. If outdoor temperature is desired, simply mount the remote
sensor outside. It is recommended to mount the sensor on the North side of the house
away from sources of heat or cold (away from direct sunlight, windows, vents, etc.).
4. The range of the sensor is 80 feet in open space. While the signal is able to penetrate
walls, it will decrease the range. Concrete and metal structures offer the most
resistance.
5. The sensor should not be mounted on a metal surface.
6. The sensor and projection alarm should be kept away from other sources of possible
interference including cordless appliances (telephones, baby monitors), microwave
ovens, and other strong electrical appliances.
7. The remote temperature is displayed in °F.
