with a screwdriver or coin. The 4 batteries must always be the same brand and replaced at the same
time. Fit the batteries in carefully in the direction indicated inside the compartment.

n Reception/transmission test to be conducted before each excursion. The tester sets his avalanche
transceiver for transmission and each member of the group verifies that his transceiver in reception mode
detects him correctly. The operation to be conducted in reverse so that ALL transceivers in the group are
checked in both transmission and reception modes.
Possible anomalies...
The ARVA Evo3 conducts a self-test every five minutes to check the status of the batteries, the locking onto the
frequency, transmission power, etc.
If the device detects an anomaly, a long 5-second beep will be heard, 3 times separated by 5 minutes.
Two cases are possible:
• The capacity of the batteries has dropped to 20% (the device can still transmit for 48 hours or search for 1⁄2
hour). After the long 5-second beeps, 20% will remain lit on the LCD display to remind you to change the
batteries as quickly as possible.
• Technical transmission or program problems, after the long 5-second beeps, the LCD screen displays
Er (= Error). Do not leave with the device in this last case.
Exclusive features of the ARVA Evo3:
• A powerful 457 kHz ±20 Hz transmitter transmission level does not depend on battery
status.
• The search band width is 40 m.
• A multi-victim indicator and an automatic locking on the closest victim.
• Function: blocking of the victim which allows the isolation of the victim found to its vicinity in order
to locate further victims (in the case of multiple burials).
• A self-test of the locking onto the transmission frequency and power every 5 minutes.
• 16-bit processor with extremely rapid analysis speed
