Transmitting And Receiving Control - Ortovox F1 classic Mode D'emploi

TRANSMITTING AND RECEIVING CONTROL

E
If the light doesn't begin to flash even though new batteries
1
have been inserted, the 457kHz transmitter must be
defective. Please send your device directly to an ORTOVOX
service center.
Once turned on, a short transmitting signal can be heard
2
after switching the beam into receiving mode. Then the typi-
cal receiver rustle follows. Its volume is controlled by the
volume control switch. Turning the switch clockwise decrea-
ses it, i.e. from a higher to a lower search zone. In this
manner, the function of the amplifier and the loudspeaker is
tested as well. No signal will be heard, however, if the
switch is already in the receiving mode when it is turned on.
The function of the earphone can be tested in the same way.

Earphones are sensitive to high temperatures. At temperatures of more than
+ 45° C, its crystal may be damaged (loss in function or total failure). Do not expose
your earphone to the sun!
The maximum transmitting and receiving range can be checked as follows:
Please put the transmitting F1 classic horizontally on the snow surface
• Go away from the transmitter for about 100 m
• Turn your F1 classic on receive mode and approach the transmitting transceiver.
• The antennae of both avalanche transceivers are coaxial
(the antennae have the same axis)
