4.11 Range information
The range of the handset is ca. 50 metres in closed rooms and ca. 300 metres outdoors. When there is a
good contact with the base station, the aerial symbol will come on in the display. If you are too far away from
the base station, the aerial symbol will flash. In this case, move nearer to the base station once more, as
otherwise the call will be interrupted.
4.12 Paging from the base station to the handset
If you cannot remember where you have left the handset, press the button on the base station. You will
hear the handset audible signals for 30 seconds and thus be able to find it again easily. You can cancel the
audible signal prematurely by pressing the STOP display button.
4.13 R signal button
If you have connected your telephone to a private exchange, you can use all the facilities such as call transfer,
automatic recall, etc. The "R" signal button gives you access to these facilities. The FLASH time "100ms"
(factory setting) or "300ms" will be required on a private exchange. You can find out from the dealer from
whom the equipment was purchased whether your telephone will work on your private exchange without any
problems.
You can find out how to change the FLASH time in Chapter 8.2.4.
