Recalling the most recent signal
The »lisa RF time flash« stores each
signal it receives for a period of 3
minutes.
During this time, you can call up the
signal again by pressing the Light/
Snooze lisa signal cancel switch button. The signal is then displayed on
the indicator LEDs. A flash signal is
not triggered.
Radio range
The lisa transmitters are designed to
have a radio signal range of 80 meters under optimum conditions.
The following conditions may result in
a reduced range:
-
Signal transmission through building
structures or vegetation
- Interference from TVs, computer
monitors and mobile phones. Under
certain circumstances, this may
prevent the receiver from functio ning at all.
- Positioning of the transmitter at an
unfavorable distance from surfaces
which reflect radio waves, for ex ample floors and walls. This may
lead to the signal wave being wea kened or even cancelled out by the
reflected wave.
- Metallic objects reduce the range
due to the shielding effect of the
metal.
- Particularly in towns and cities, there
maybe many other sources of radio
waves which can disrupt the original
signal.
- Having units operating at similar fre quencies located close to one an other may also result in mutual inter ference.
Special aspects

•Thequartzmechanismofthealarm
clock has a backup power supply.
The clock will continue to operate
for about 2 hours if there is a power
failure. The alarm function and the
illumination are deactivated during
this period.
• The clock face illumination is also
activated when the alarm is trig gered.
•Inadditiontothe greenmarking of
the Alarm ON/OFF switch, the
snooze button is also illuminated
when the alarm is triggered.
•The »lisa RF time flash« uses a
chase light for signalling an alarm.
During an alarm the 6 LEDs at the
frontside will be switched alternate ly, creating the chase light.
•The »lisa RF time flash« converts
the various transmission signals
(Telephone, Doorbell I+II, Baby monitor, Pager, Alarm, Water alarm,
Fire alarm) into varying sequences
of flash and signal displays.
