- Positioning of the transmitter at an
unfavourable distance from surfa-
ces which reflect radio waves, for
example floors and walls.
This may lead to the signal wave
being weakened 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 may be many other sources
of radio waves which can disrupt
the original signal.
- Having units operating at similar
frequencies located close to one
another may also result in mutual
interference.
Power failure backup
The battery can provide backup
power for a mains power outage of
up to 72 hours. All functions are avai-
lable during this period.
Battery empty
If the pager LED lights up without a
lisa signal the battery voltage is too
low.
Symptom: Flat battery indicator
(Pager LED) lights up permanently.
Cause: Power supply unit isn't
connected to the lisa RF time.
Battery is faulty - replace battery with
a new one.
Attention: Use only a NiMH battery.
After the unit has been disconnected
12 English
from the mains supply for several
months it must be plugged into the
mains supply for several hours befo-
re the unit will function reliably on
batteries again.
