4.2 CARRYING SYSTEM
We recommend using the carrying system supplied or an approved clothing pocket. To
protect the display, wear the avalanche beacon with the display facing inward. The
transmission control LED remains visible even when the avalanche beacon is stowed
in the carrying system.
The design ensures that the avalanche beacon is secured after insertion in the carrying
system and is also held in place by the yellow strap. The carrying system must always
be worn under at least one layer of clothing. This prevents loss or damage in the event
of a fall or avalanche.
If you carry the avalanche beacon in an approved clothing pocket, make sure that there are no other sharp, metallic
or electronic objects (e.g. keys, coins, cell phone) in the pocket that could damage or interfere with the avalanche
beacon.
Place the avalanche beacon in the carrying system with the display facing inward and gently press down until it
"clicks" into place. Secure it with the yellow tab.
To remove the device, open the yellow tab. Take the avalanche beacon in your hand and place your thumb in the
center of the top of the device. Turn the top of the beacon outward, away from the carrying system.
CAUTION
Risk of device loss if worn incorrectly.
Store your PIEPS PRO IPS in the carrying system provided!
Fasten the device by means of the fastening loop!
GOOD TO
KNOW
Wearing a pacemaker
For Medtronic and Boston Scientific pacemakers, we recommend a distance of at least 20 cm.
For other manufacturers, we recommend an increased distance of 50 cm (secured in a pants
pocket) due to a lack of data.
When things have to go fast
The PIEPS PRO IPS can also be inserted into the carrying system with the antenna folded out,
i.e. in search mode. This can be helpful in multiple burial scenarios when the first buried person
has been successfully located and others are searching for additional buried victims. In case
of secondary avalanche, the PRO IPS has the auto-revert function, see chapter 4.6.2.
4.3 SWITCH ON | SELF-CHECK
Unfold the antenna to the middle position, press the ON/OFF button and fold the antenna again until it touches
the housing. After switching on, the following information is displayed: Firmware version (e.g. 1.0)(A), progress of
the self-check (arrows from left to right), result of the self-check: OK(B), W for warning, ER for error(E), battery
capacity and battery type: AL for alkaline, Li for lithium. At this point the countdown of the group test (C) is running.
After this countdown, your PIEPS PRO IPS switches to
SEND mode (D): the transmission control LED starts to flash green and the device vibrates three times in succession.

4.4 GROUP-CHECK
Despite the extensive self-check,
PIEPS recommends carrying out an
avalanche beacon check before every
tour as a standard measure! The
PIEPS PRO IPS offers a group-check
function with two modes. These are
useful features with larger groups. In
both regular and Group-check PRO
mode, the reception range is limited to
1 m.
The "Simple Group-check" is sufficient
for checking modern, digital 3-antenna devices.
The "Extended Group-check" is recommended for checking old devices (analog 1-antenna devices).
Group-check REGULAR MODE
In regular group-check mode, you can test whether the avalanche beacons in your group are transmitting correctly.
To enter the regular group-check mode, fold the antenna into the
SEARCH position (I) and press the ON/OFF button. After the self-check, press
the FUNCTION button while the countdown for the group-check is active (K).
During group-check, the distance between the individual members
of the group must be at least 5 m. The group-check mode is active for 60 seconds and
ends automatically after the countdown has been completed. To
remain in group-check mode, press the FUNCTION button
during the countdown. You can exit this mode at any time by pressing the FUNCTION button,
or folding in the antenna again.

4.5 SEARCH MODE | SEARCH STRATEGY
4.5.1 Avalanche emergency
A buried person has the best chance of a rapid rescue if as many group members as possible have not been buried
and if they are able to rescue their companions efficiently as a team! If the worst comes to the worst, the most
important thing is: KEEP CALM, OBSERVE, ALERT, ACT IN A COORDINATED MANNER!
(1) Keep calm & get an overview
•Are there any other dangers?
•Number of people buried?
•Define primary search area!
(2) Make a short emergency call
•max. 2 min
•EU 112, AT 140, CH 1414, IT 118, FR 15
(3) Search for buried persons
•Signal search (eye + ear, avalanche beacon)
•Coarse search (from first reception)
•Fine search (from 5 m on the surface)
•Point search (systematic probing)

4.5.2 Signal search
Start searching (signal search) in the primary search area. With its optimized technical platform for avalanche
beacons, your PIEPS PRO IPS has the ideal reception range and thus enables correct direction and distance
indication from the first reception - a special mode of operation such as turning/pivoting is not necessary. All
beacons in SEND mode that are within the maximum reception range are received simultaneously.
Walk swiftly along the defined search area in the specified search strip
width. The recommended search strip width for your PIEPS PRO IPS is 80
m. The display shows this search strip width and a "no reception" symbol
until a signal is received (A).
no reception
GOOD TO
KNOW
Search strip width
The search strip width of your PIEPS PRO IPS is 80 m, as indicated on the upper left corner on
the display. In case of interfering signals, the PRO IPS shows a reduced search strip width: 60 m,
40 m or 20 m.

CAUTION
Behavior during signal search
All participants, including the observers, switch their avalanche beacons to receive mode (or to
backup mode, see chapter 4.6.7). Please also observe the distance recommendations for
external sources of interference!
4.5.3 Coarse search
As soon as the avalanche beacon receives a signal, it begins to vibrate and beep, with an arrow indicating the
direction to the
buried victim (B). Quickly follow the indicated direction and check whether the distance value decreases. If the
distance value increases, you are moving in the wrong direction. In this case, the displayed arrow points at you
and prompts you to turn around (C). When the distance to the buried person is less than 10 m, the direction arrow
changes to an outline to remind you to reduce the search speed (D).
Reverse arrow

Operating Instructions PIEPS PRO IPS | Firmware v1.0 | 10/2023 17 / 31
GOOD TO
KNOW
An estimation algorithm for the distance values ensures that the reversing arrow is only
shown when the display is reliable.

GOOD TO
KNOW
Behavior during coarse search
Work quietly and with concentration in SEARCH mode. Avoid hasty movements!
GOOD TO
KNOW
Vibration on first reception
Your PIEPS PRO IPS additionally indicates first reception by means of a vibration signal (E)!
This allows the focus to be placed on the visual surface search when searching
for signals!
4.5.4 Fine search
From an approach of 5 m, the search speed should be significantly reduced (50 cm/s). At the same time, work as
close to the snow surface as possible.
To prevent confusion during the fine search, the direction arrows are hidden below 2 m distance. Reduce the
search speed again, move the avalanche beacon slowly and as close as possible over the snow surface, and search
for the point with the shortest distance indication by using a grid pattern. The dynamic sound output supports the
fine search: the closer, the faster the sounds are emitted.
GOOD TO
KNOW
Every second counts.
In an emergency, every second counts. For your companions under the avalanche, every second
feels much slower than for you on the snow surface. This could lead to a panic attack. With the

Operating Instructions PIEPS PRO IPS | Firmware v1.0 | 10/2023 18 / 31
PIEPS iPROBE you are up to 3x faster during fine and point searches.
The PIEPS iPROBE is compatible with all avalanche beacons.
Perform the last direction correction exactly before the direction
arrow disappears. You then move towards the transmitting
avalanche beacon in the best coupling position and save time when
searching in a grid pattern.
Do not make any fast movements
during the fine search, reduce the
search speed to 10 cm/s when searching
in a grid pattern and avoid
turning/swiveling! Search along the Y-
axis to the point with the shortest
distance indication, then search along
the X-axis. Always search beyond the
point with the shortest distance
indication to verify the distance
indication. Mark the point with the
shortest distance indication and start
probing systematically.
4.5.5 Point search
Start at the point with the shortest distance indication. Always probe
at right angles to the snow surface. Use the lower hand as a "probe
guide" to ensure that the probe follows a consistent path. Follow the
proven system until you get a hit. Communicate a hit and leave the
probe stuck.

KNOW
PIEPS iPROBE.
The PIEPS iPROBE provides optimum support in this phase by means of an visual and acoustic
hit indication in the vicinity of the buried victim. At a distance < 50 cm from the buried victim, a
continuous tone is emitted.
4.5.6 Multiple burial | MARK function
A multiple burial is clearly indicated to you by the number of "figures" on the display (F).

Operating Instructions PIEPS PRO IPS | Firmware v1.0 | 10/2023 19 / 31
MARK
Marking is possible from a distance of 5 m and is indicated by the MARK symbol. To mark ("hide") a localized
beacon, briefly press the MARK button. Successful hiding is confirmed with a frame around the "figure” (G).
The PIEPS PRO IPS automatically displays the next strongest signal within the
reception range on the display. If there is no other signal within the reception range,
the display shows "signal search".

GOOD TO
KNOW
Continuous carrier display | old unit display
Older analog devices send a weak continuous signal in addition to the pulse signal. It is
recommended to move a few meters away after marking such an avalanche beacon to
minimize any influences.
Signal without continuous carrier
Signal with continuous carrier
If your PIEPS PRO IPS detects such a continuous signal, the "figures"
start to blink.
4.6 PIEPS IPS TECHNOLOGY AND OTHER HELPFUL FUNCTIONS
Maximum background support in SEND and SEARCH mode!
4.6.1 PIEPS IPS technology
IPS - INTERFERENCE PROTECTION SYSTEM IN SEND MODE
PIEPS IPS is a unique technology that continuously monitors the effects of electronic interference on the beacon
by processing the interfering signals and adapting to them IMMEDIATELY . In this way, your PIEPS PRO IPS will
provide optimum transmission performance despite any interference that may occur.
IPS - INTERFERENCE PROTECTION SYSTEM IN SEARCH MODE
The PIEPS IPS technology provides the optimal electronic hardware platform for avalanche beacons. This
technology allows the signal to be received and processed SIMULTANEOUSLY on the X and Y antennas. This
unique Dual Antenna Signal Processing (DASP) feature enables an optimal and reliable detection. In addition,
compared to other beacons that have a typical design with a fixed arrangement of X and Y antennas, PIEPS PRO IPS
achieves the MAXIMUM DISTANCE to a user's wearable electronic devices, such as a smartwatch, GPS wristwatch,
etc., due to the design of the X antenna.
PIEPS Advanced Signal Verification | Support in SEARCH mode
Only a verified signal is displayed. Your PIEPS PRO IPS will not confuse you by displaying "ghost signals"! This
function has been optimally implemented with PIEPS IPS technology.
External interferences and distance recommendations
All avalanche beacons are inherently sensitive to sources of electrical and magnetic interference. Therefore, we
recommend to keep the minimum distance in SEND mode: 20 cm, and in SEARCH mode:50 cm to electronic,
magnetic as well as metallic influential factors (cell phone, radio, key ring, magnetic lock, action cams, avalanche
backpacks, etc.).
