Acoustic Emergency Reception - Ortovox S1 Mode D'emploi

ACOUSTIC EMERGENCY RECEPTION (SAFETY SETTING)
Receiver Transmitter
Increase Volume Deacrease
The ORTOVOX safety emergency reception allows an acoustic search even
when the batteries have almost completely run out. When a battery change
has been delayed (remaining capacity less than 10 %), sensors and display
are automatically switched off, as the minimum current supply is no longer
reached. Now only an acoustic reception is available.
Switching "acoustic emergency reception" on and off
The acoustic emergency reception can (also for training purposes) be switched
on at any time by simultaneously pressing the buttons "OK" (2) and "menu" (3)
for at least 5 seconds or using the menu heading "Acoustic location".
Switching off the acoustic emergency reception:
Close the S1 and open it again or hold down both the "OK" (2) and "menu" (3)
buttons again at the same time for at least 5 seconds. If the battery capaci-
ty is very low the S1 is automatically switched to the highest possible recepti-
on level for emergency acoustic reception. The 'OK' button is used to reduce
the signal. The 'menu' button is used to increase the volume level. After initi-
al reception the loudspeaker will sound the transmission signal. TURN
the S1 in order to determine the direction with the strongest recep-
tion. Now the searcher will move in this direction for 5 m, redu-
cing the volume if necessary. Then the searcher once again
turns the S1 to the direction with the highest volume and
again moves 5 m in this direction. The volume increases
as the searcher moves closer to the avalanche vic-
tim. During the fine search (= lowest reception
level) do not turn or tip the S1. Now mark
–
the point in the longitudinal direction with
the loudest signal. A search is also made
+
for the loudest signal to the right and left of
this point. The avalanche victim is located at
the point with the loudest signal.
