D. EL BACKLIGHT
1. The projection alarm has an EL backlight designed for night viewing.
This will light up for 2 seconds whenever a button is pressed.
2. The EL backlight cannot be turned on constantly; this would drain the
batteries and burn out the EL.
E. INDOOR TEMPERATURE
1. The Projection Alarm measures indoor temperature with an internal
sensor.
2. This temperature is displayed in
°F or °C, depending on the time
format (12 or 24 hour mode). When in 12-hour format, the
temperature will be in
°F. When in 24-hour mode, the temperature
will be in
°C.
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. 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 sensor 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 or °C, depending on the
time format (12 or 24-hour mode). When in 12-hour format, the
temperature will be in
°F. When in 24-hour mode, the temperature
