2.3 RESIDUAL RISKS | WARNINGS
Even though the PIEPS beacon has been designed with maximum care and all safety-related facts have been
taken into consideration, residual risks may exist and must be evaluated by means of a risk assessment. All
residual risks and warnings from the risk assessment are listed in this chapter.
INTERFERENCE WARNINGS
All beacons are very sensitive to electronic, magnetic and metallic sources of interference.
PIEPS beacons are designed to minimize interference (Auto-Antenna Switch in SEND mode, Signal Verification in
SEARCH mode), but it is the user’s responsibility to follow some basic best practices:
•Avoid carrying unnecessary electronics.
•Maximize distance between the beacon and any sources of electronic, magnetic, and metallic
interference (such as mobile phones, smart watches, radios, keys, heated garments, electronic airbags
and magnetic closures).
•A minimum distance of 20 cm for a beacon in SEND mode, and 50 cm in SEARCH mode is recommended.
•When in SEND mode, carry the beacon on the front side of your body.
•When in SEARCH mode, maximize distance by holding the beacon in a partially outstretched arm in front
of your body.
•Advanced planning should be considered to ensure that smart watches, heated gloves, and similar items
that are likely to remain very close to a searching beacon are kept at least 50cm away.
NOTICE! The user is responsible for keeping their beacon firmware up to date.
PIEPS recommends checking for updates at the beginning of every season, and
checking monthly when equipment is in regular use.
2.3.1 PIEPS interference protection
•PIEPS Auto-Antenna-Switch | protection in send mode
If the transmitting antenna is impacted by external interference, the other antenna would take over the
transmit function. The PIEPS PRO BT/POWDER BT always transmits with the strongest possible signal!
•PIEPS Signal Verification | protection in search mode
Only a verified 457kHz signal is indicated. The PIEPS PRO BT/POWDER BT doesn´t confuse with ghost
signal indication!

4.5 HELPFUL PIEPS BACKGROUND FEATURES
4.5.1 PIEPS iPROBE-Support
Beacons with iPROBE-support* get automatically deactivated when probing with the electronic probe PIEPS
iPROBE. This prevents signal overlaps and the next-strongest signal is automatically shown on the display of the
receiving beacon. Maximum support in multiple burials!
•At beacons with software version 1.1 or lower the PIEPS iPROBE support is activated automatically.
•At beacons with software version 2.0 or higher the PIEPS iPROBE support is disabled by default and can
be enabled in the PIEPS APP device manager.
* Beacons with iPROBE-Support: PRO BT/POWDER BT, PIEPS MICRO BT sensor/button/RACE, PIEPS DSP SPORT,
PIEPS DSP PRO/PRO ICE, PIEPS DSP STANDARD/TOUR ≥ v5.0, PIEPS FREERIDE, BLACK DIAMOND
GUIDE/RECON.
External interference and distance recommendations
All beacons are very sensitive to electrical and magnetic sources of interference. Due to this, all manufacturers
recommend keeping a minimum distance from electronic, magnetic and metallic sources of interference (mobile
phone, radio, keys, magnetic closures, smart watches, heated gloves, electronic airbags, etc.):
Minimum distance in send mode: 20 cm | Minimum distance in search mode: 50 cm
4.5.2 Secondary avalanche | Auto-Search-to-Send
Auto-search-to-send, or `Auto-revert’ mode, provides an additional layer of protection
against secondary avalanche scenarios. By default, it is disabled and can be enabled in
the PIEPS APP device manager. Once enabled, the device switches from search mode to
send mode automatically after a certain time without movement (burial).
An activated AR function is shown
clearly on the display: the
transmitting symbol alternates with
AR.
The AR-function provides the following characteristics:
•Motion-controlled initialization
•Short switching timeout
•Long warning phase with alert and countdown prior to switching
•Continued alert, also after switching
With auto revert enabled, while in search mode and after the predetermined time without motion, the
transceiver will begin the auto revert process. As shown below, a countdown with an associated sound will
begin. If at any time during the countdown the mark button is pressed, the clock will be reset and the

4.6.1 In case of emergency
A buried person has the greatest chance of being rescued by an efficient companion rescue. In the event of an
accident, the following applies: KEEP CALM, OBSERVE, ALERT, ACT WITH COORDINATION!
(1) Keep calm & get an overview
•Are there any other risks?
•How many victims?
•Determine the primary search area!
(2) Make a brief emergency call
•EU 112, AT 140, CH 1414, IT 118, FR 15, NA 911
(3) Burial search
•Signal search (eyes + ears, beacon)
•Coarse search (starting with initial signal)
•Fine search (closer than 5 m on the surface)
•Pinpointing (systematic probing)

4.6.2 Signal search
Start searching in the primary search area for the initial signal detection as well as for visual/acoustic signals. All
participants, observers included, must switch their devices to search mode (or to standby mode)! Make sure to
follow the external interference distance recommendations and hold the beacon a minimum of 50cm (20") from
all electronic, magnetic, and metallic sources of interference. The PIEPS beacon has a circular receiving range
that allows a correct indication of direction and distance from the point of initial signal detection –a specific
method such as turning/rotating is not necessary. All signals of the burials that are within the maximum
receiving range are received simultaneously.
Walk the search strip width in the search
area quickly. The recommended search strip
width for the PIEPS beacon is 60 m. The
display shows “no signal”.

Vibra on initial signal detection
The PIEPS PRO BT provides additional haptic support by vibration on initial signal
detection. This lets rescuers focus on the visual surface search during the signal
search.

4.6.3 Coarse search
Follow the directional arrow quickly and check for a decreasing distance reading. Change the search direction by
180° in case of an increasing distance reading.
Turn left
Move straight ahead
Turn right
NOTICE Work calmly and with concentration in search
mode. Avoid hasty movements!
4.6.4 Fine search
From a distance of 5 m, the search speed should be notably reduced (50 cm/s). At the same time, start working
close to the surface of the snow. To prevent confusion during the fine search, the direction indication disappears
below a distance of 2 m. Reduce the search speed again and find, by cross-like movements, the position of the
lowest distance reading. A dynamic acoustic signal output supports the fine search: the closer the faster.
Do an accurate direction adjustment before the direction arrow
disappears! You are then moving to the transmitting beacon in best
coupling position and save time during the cross-like movements.
Move your beacon at a slow, steady
speed of about 10 cm/s, keep it leveled
close to the surface and do not rotate
your device. Search along the Y axis,
determine the lowest distance value,
then follow along the X axis. Always
move past the point of the lowest
distance to verify the distance
tendency. Mark the point of the lowest
distance reading and start pinpointing.

4.6.5 Pinpointing
Begin at the point of the lowest distance indicated. Always probe
perpendicular to the surface. Use your lower hand as a “probe
guide” to ensure the probe follows a steady path. Follow a proven
system until you have a hit. Communicate a hit clearly to
companions. Leave the probe stuck for shoveling guidance.
NOTICE
The PIEPS iPROBE supports perfectly through an optical and acoustic hit indication within
50cm to the burial.
4.6.6 Multiple burials | MARK function
A multiple burial is indicated clearly on the display by the number of small human figures (2G, 2H).
Marking is possible from a distance reading of 5 m and is indicated by the MARK symbol (2E). Press the button
MARK (1D) briefly to “hide” the localized transmitter. A successful flagging is confirmed by a frame around the
human figure (2J). The display then indicates the direction/distance to the next strongest signal inside the
receiving range. If there are no further signals within the receiving range the display indicates “no signal”.
prior to marking
after marking
De-mark a single signal: press the button MARK
(1D) for 3 seconds.
De-mark all: switch to send mode and then back
to search mode. With the PIEPS PRO BT you can
also use the SCAN function for a full reset.
Continuous wave indication | old-device-indication
Old analog transceivers are transmitting a continuous wave in addition to the pulse signal. To keep an impact at
a minimum, it is recommended to step a few meters away after marking such a transmitter.
Signal without continuous wave
Signal with continuous wave
The PIEPS beacon identifies a continuous wave and supports
visually by flashing human figures.
