4. GENERAL DESCRIPTION
4.1 SENSOR INFORMATION
The proximity-sensor (1F) is used for automatic switching from Send to Search mode. The sensor detects whether
it is covered or not. This feature also works in darkness.
To prevent accidental switching back to Send mode during the search, Search mode is blocked (SEARCH-LOCK, 2G)
as soon as you take the MICRO out of its carrying system. The MICRO remains in the locked Search mode even if
you return it to the carrying system during probing or digging. To return to send mode, release the SEARCH-LOCK
(1C) and place the device in the carrying system. See also chapter 4.7 & 4.8.

4.3 QUICK START IN 3 STEPS
Your PIEPS MICRO is ready for use directly out of the box.
Step 1: Place the carrying system by laying the strap over your head and
shoulders. Pass the body belt around your back, connect the quick release and
adjust to the required length.
Step 2: Switch the MICRO on (main switch 1J ON) and wait for it to complete the
self-check.
Step 3: Place the MICRO in the carrying system, check the Transmit control LED
(1B) and enjoy your tour.
PIEPS recommends using the MICRO carrying system (A) or using the MICRO Bag
with hand-loop (B), if the MICRO is carried in a securely closeable clothing
pocket.
4.4 SWITCHING ON | SELF-CHECK
Switch the MICRO on by turning the main switch (1H) to the ON position.
The display shows the current firmware-version and the selected battery type. At the same time, an extensive
self-check is performed and all relevant system components are tested.
A minimum distance of 5 m from other devices and all electronic, magnetic and metallic
sources of interference should be kept during the self-check. Ensure that the sensor is not
covered during the self-check.
If the self-check is successful, “OK” is indicated on the display. In the event of a device warning, an alert signal
sounds and the display indicates “E” in combination with a warning-code.
A covered sensor during the self-check leads to a warning: the MICRO beeps and vibrates and “ST” for “Sensor
test error” is shown in the additional display (2B). (see also chapter 6.1)

Manual PIEPS MICRO | Firmware v2 | 07/2017 11 / 23
4.5 GROUP CHECK
Despite the extensive self-check, PIEPS recommends that all users perform a beacon check before each tour. The
MICRO is equipped with a group check function. This simply and efficiently checks whether the partner avalanche
beacon is sending (send check) and whether the send parameters meet the standard.
Activating the group check function:
Switch the MICRO on
Wait until “Group check” appears on the display.
Press and continue to hold the MARK button
3-second-countdown
The group check function is active as long as the MARK button is pressed. Release the MARK button to end the
group check function. After a countdown of 3 seconds, the MICRO automatically switches to Send or Search
mode:
Sensor covered => Send mode
Sensor not covered => Search mode
The group check function can be activated again during the 3-second countdown.
The maximum range in group check mode is 1 m.
Fast and Extended group check
The MICRO has two group check modes:
Fast group check: checks transmitting signal and frequency
Extended group check: checks transmitting signal, frequency, signal duration and period duration
Fast group check
CF = Check Fast
Extended group check
CE = Check Extended
The “Fast group check” mode is set by default. The required mode can be selected in the PIEPS APP (see also
chapter 5).
The “Fast group check” is sufficient for checking modern, digital devices with 3 antennas.
The “Extended group check” is recommended for checking old devices (analog single-antenna devices).

4.6 SEND MODE
After the self-check or the group check, place the MICRO into the carrying system. The MICRO transmits and an
LED indicator light (1D) flashes.
To see the display in send mode, cover the sensor (1F)
after unlocking the SEARCH-LOCK beforehand as
necessary.
If the sensor remains uncovered after the start
sequence, the MICRO switches immediately to Search
mode.
Send mode display
4.6.1 Send-Vibra
The Send-Vibra is an additional, tactile send confirmation. When
the MICRO sends, it vibrates 5 times.
The Send-Vibra is activated by default. The feature can be
deactivated in the PIEPS APP (see also chapter 5).

Manual PIEPS MICRO | Firmware v2 | 07/2017 14 / 23
4.6.2 The Intelligent Transmitter –maximum support in send mode
The Intelligent Transmitter is working in the background and helps to find a buried person faster and more
efficiently in case of an emergency.
PIEPS Auto-Antenna-Switch
If the transmitting antenna is negatively influenced through external interference (e.g. mobile phone), the other
antenna will take over the transmitting function. The MICRO always transmits with the strongest antenna for the
maximum range to the receiving beacon!
PIEPS iPROBE-Support
Beacons with iPROBE-support* are 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. The PIEPS iPROBE-supports maximal in the case of multiple burials!
* Beacons with iPROBE-Support: PIEPS MICRO, PIEPS DSP PRO, PIEPS DSP PRO ICE, PIEPS DSP SPORT, PIEPS DSP
STANDARD ≥ v5.0, PIEPS DSP TOUR, PIEPS FREERIDE
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, etc.):
Minimum distance in Send mode: 20 cm | Minimum distance in Search mode: 50 cm
4.7 SWITCHING SEND SEARCH
The MICRO automatically switches to Search mode when you remove it from the carrying system.
The MICRO automatically switches to Search mode when you remove it from the carrying system. Search
mode is blocked in this case (SEARCH-LOCK).
The MICRO automatically switches to Search mode if you do not place it in the carrying system after the
start sequence (switch-on). Search mode is not blocked in this case.
4.7.1 SEARCH-LOCK
To prevent accidental switching back to Send mode during the search, Search mode
is blocked as soon as you take the MICRO out of its carrying system. The MICRO
remains in Search mode even if you return it to the carrying system during probing
or digging.
SEARCH-LOCK display
The SEARCH-LOCK is only activated when the device was previously in Send mode.

Manual PIEPS MICRO | Firmware v2 | 07/2017 15 / 23
4.8 SWITCHING SEARCH SEND
If necessary, you can release the SEARCH-LOCK, by pressing the MARK button (1A) for 3 seconds and placing the
MICRO in the carrying system or covering the sensor.
The MICRO emits an acoustic and tactile (Vibra) warning for 4 seconds that the device will switch over from
Search to send mode. A tactile send confirmation is performed after the switchover (see also chapter 4.6.1).
IMPORTANT! When you start the tour again, take care that the SEARCH-LOCK is not blocked, when you put the
MICRO in the carrying system. Only if the SEARCH-LOCK is not blocked, the MICRO switches to send-mode
automatically.
4.8.1 Secondary avalanche | Auto-Revert Search-to-Send (AR)
The MICRO has the Auto-Revert Search-to-Send (AR) function by default. The device switches from Search to send
mode automatically if the device has not been in motion for 1 minute (buried). You can change the timeout for
the switchover in the PIEPS APP (see also chapter 5).
The AR function has the following features:
Motion-controlled initialization
Short switching time
Long warning phase with signal tone and countdown before switching over
Permanent warning tone, also after switching over

4.9 SEARCH MODE | SEARCH STRATEGY
4.9.1 In case of emergency
A buried person has the greatest chance of being rescued quickly if as many of the companions in the group were
not buried and these people are able to work efficiently as a team. In the event of an accident, the following
applies: REMAIN CALM, OBSERVE, ALERT, ACT WITH COORDINATION!
(1) Stay calm & get an overview of the situation
Are there any other risks?
How many victims?
Determine the primary search area!
(2) Make a brief emergency call
Max. 2 minutes
EU 112, AT 140, CH 1414, IT 118, FR 15
(3) Burial search
Signal search (eyes + ears, beacon)
Coarse search (starting with first signal)
Fine search (closer than 5 m on the surface)
Pinpointing (systematic probing)
(4) Systematic digging

4.9.2 Signal search
Start searching in the primary search area for initial detection (signal search). The MICRO has a circular receiving
range and enables the correct indication of direction and distance indication from the first signal –a specific
method such as turning/pivoting is not necessary. All signals of the burials that are within the maximum receiving
range are received simultaneously.
Walk along the defined search area in the stated search strip
width quickly. The recommended search strip width for the
MICRO is 50 m. The display shows “no signal” until a signal is
received.
No signal
One rescuer with skis
for signal search
One rescuer by foot

d = search strip width
IMPORTANT! All participants, including the observers, must switch their devices to receiving mode (or to standby
mode). Always make sure there are no electronic devices (e.g. mobiles, radios) or solid metal items in the direct
vicinity of the search.
4.9.3 Coarse search
As soon as the MICRO receives signals, the distance and direction to the strongest signal are shown on the
display. The number of victims located within the receiving range is indicated by the number of matchstick men.
Using the arrow and distance reading, follow the strongest of the received signals along the field lines.
Vibra at initial detection
The MICRO provides additional support during initial detection by vibrating. This
lets rescuers focus on the visual surface search during the signal search.

As soon as a signal is received, follow the directional arrow quickly and see if the distance figures reduce. If the
distance figures increase, change the search direction by 180°.
Turn left
Move straight
ahead
Turn right
IMPORTANT! Work calmly and with concentration in Search
mode. Avoid hasty movements!
4.9.4 Fine search
From a distance of 5 m, the search speed should be notably reduced (50 cm/s). At the same time, work with the
MICRO as close to the surface of the snow as possible in this phase of the search to keep the distance to the
transmitting beacon to a minimum.
To prevent confusion during the fine search, the direction indication is hidden below a distance of 2 m. Reduce
the search speed again and search by pinpointing the position of the smallest distance indicated. Work slowly and
on the surface of the snow.
The dynamic acoustic signal output supports the fine search: the close the higher/faster.
TIP! Before the direction arrows are suppressed, the
last distance correction has to be done exactly. You are
then moving to the transmitting beacon in best
coupling position and save time during the cross-like
movements. In the case of a deep burial it could
happen that the minimum direction indication is higher
than 2 m.
IMPORTANT! It’s strongly recommended to avoid hasty
movements (move approx. 10 cm/sec) and avoid
turning and rotating.

Manual PIEPS MICRO | Firmware v2 | 07/2017 19 / 23
4.9.5 Pinpointing
Check the search result by systematic probing. Begin at the point of the lowest distance indicated. If you
encounter something, insert the probe and start with systematic digging.
4.9.6 Multiple burials | MARK function
If there are multiple burials, this will be indicated clearly on the display by the number of matchstick men.
To mark (“hide”) a localized sender, press the MARK (1A) button briefly. Once it is hidden, this will be confirmed
by a frame around the matchstick men (2N). The MICRO automatically shows the next strongest signal on the
display.
Now continue searching as described earlier and repeat the process until all transmitters are located. If there are
no further signals within the receiving range the display indicates “no signal”.
Indicator before
marking
Indicator after marking
Marking is possible
within a range of 5 m
and is indicated by the
MARK (2J) symbol.
Continuous carrier indication
Older analog transceivers are transmitting a weak continuous signal additional to the digital pulse signal that can
have an impact on the digital signal separation. It is recommended to quickly step a few meters away after
marking such a transmitter.
Signal without continuous carrier
Signal with continuous carrier
The MICRO identifies such a continuous signal and supports it
with an indicator: the “number of burials” start flashing.
