EMERGENCY RECEPTION - SAFETY CIRCUIT

If battery replacement
has been delayed
(residual capacity less
than 10 %) then micro-
processor and display
will be switched off
automatically to con-
serve battery power.
Instead of the digital
search, now analog

emergency reception

is available until the bat-
teries are completely
dead.
To determine the stron-
gest receive direction
the searcher moves in
this direction. Volume
increases as the sear-
cher gets closer to the
victim.

IMPORTANT INFORMATION!
Remove the batteries from the avalanche trans-
ceiver during the summer months. The ORTOVOX
factory guarantee is invalid by damage due to bat-
tery leakage. Never use rechargeable batteries
(rechargeable batteries such as Ni-Cd cells).
Rechargeable batteries have significantly lower
operating voltage, and thus lower range and limi-
ted service life. In addition defective rechargeable
batteries cannot be detected immediately. Once
they have been recharged they show full battery
voltage, however they can drop off to 0 after
extremely short service (life threatening hazard!).
If you delay changing batteries (capacity <10%),
the micro-processor, the distance display, and
direction display will switch off. In such case,
approximately only twenty hours of emergency
analog transmit operation and one hour of emer-
gency receive operation are possible.
