BATTERY CHARGING
Always make sure the system has a full charge before heading out into ava-
lanche terrain.
A
WARNING! Charge Lithium batteries only under supervision!
A
WARNING! The airbag may deploy if the Deployment Handle is pulled
anytime the lights are illuminated, even during charging .
1. Locate the Charging Power Supply (1o) and install the correct international
plug.
2. Locate the charging connector inside the Deployment Handle Pocket (1b).
3. Unzip and expose the Charging Plug (1h).
4. Plug the Charging Power Supply (1o) cable into the Charging Plug (1h).
5. Plug the Charging Power Supply (1o) into an electrical outlet.
6. The Deployment Handle (1c) will illuminate a solid green light within the
System Status Lights (1e). The charge level is shown by the solid blue Charge
Status Lights (1f) with one blue light blinking to indicate charging state.
7. Charge until the Deployment Handle (1c) shows full charge with 4 solid blue lights.
a. First time charging can be as long as 12 hours.
b. Typical charging time is less than 6 hours.
8. Charge the Lithium-Ion Battery (1g) at room temperature. Do not charge
at temperatures outside of range (5°C - 40°C / 41°F - 104°F). At these
extremes, the system will indicate a charge temperature warning (refer to
Troubleshooting section of this manual) until the battery temperature is
inside charge range again – then charging starts automatically. It can take up
to one hour until the battery temperature reaches the required level.
9. Discontinue charging and refer to the Troubleshooting section of this manual
when you see a solid red System Status Light (1e).
CHECKING THE BATTERY STATUS AND WHEN TO RECHARGE
1. Tap the red Power Button (1d) briefly at any time to illuminate the Charge
Status Lights (1f and Figure 6).
a. 4 blue lights: full charge (maximum number of deployments available).
b. 3 or 2 blue lights: partial charge (multiple deployments available).
c. 1 blue light: at least 1 deployment remaining at -30°C (-22°F).
A
WARNING! After checking the battery status, wait until the Charge Status
Lights (1f) have turned off before arming the system .
2. A blinking red System Status Light (1d) with a single blinking blue light indi-
cates the battery is not sufficiently charged for a deployment. Do not enter
avalanche terrain.
3. Check the battery status the night before you intend to use your JetForce BT
backpack, and charge the battery if there is less than a full charge. Best prac-
tice is for the battery to be fully charged before heading out.
WEARING THE PACK (FIGURE 3)
Proper fit and secure attachment to your body is critical.
1. Put the backpack on your back with both arms through the shoulder straps.
2. Insert the Left Side Buckle (3a) through the Right-Side Buckle (3b), then
tighten the straps for a secure fit.
3. Locate the Leg Strap (3c) stored inside the Leg Strap Storage Pocket (3d).
Wrap the Leg Strap back around the back of your right leg, then between
your legs. Clip the Leg Strap Clip (3e) through the Leg Strap Loop (3f).
4. If the leg strap is too tight or too loose adjust it at the metal adjustment
buckle at the base of the right shoulder strap. Ensure the strap is doubled
back through the buckle.
5. Buckle and tighten the Sternum Strap (3g).
6. Adjust the shoulder straps to distribute the load between the shoulders and
waist.
ARMING THE SYSTEM (FIGURE 4)
A
WARNING! It is critical that the system be armed before entering ava-
lanche terrain .
1. Unzip the Deployment Handle Pocket (1b) in the shoulder strap and expose
the Deployment Handle (1c).
2. To arm the system, press and hold (~3 seconds) the red Power Button (1d) on
the bottom of the Deployment Handle (1c) until the fan briefly runs. Release
the button upon hearing the fan run.
3. Be sure to disarm the JetForce BT system when not in use.
SYSTEM STATUS LIGHTS
1. After arming, the system should show a pulsing green System Status Light
(1e) indicating the system is armed and ready for deployment. Also see
Figure 7.
2. In any system state (armed, charging, calibration), the JetForce BT system
provides comprehensive self-diagnosis. Warnings or errors are indicated
with the red System Status Light (1e). For error indications, refer to the
Troubleshooting section of this manual.
DEPLOYING THE AIRBAG (FIGURE 4)
With the backpack on and all straps securely fastened and the system success-
fully armed and showing a pulsing green light, the airbag can now be deployed.
1. Grasp the Deployment Handle (1c) and firmly pull downward to turn the
fan on.
2. The airbag will begin to deploy immediately. The fan will run at full power for
9 seconds, followed by lower speed operation and short refilling bursts for 3
minutes.
3. The airbag will deflate after 3 minutes and then automatically switch back to
armed mode.
4. To interrupt the inflation/deflation process after the initial 9 second deploy-
ment period and return to armed mode, press and hold the red Power Button
(1d) for ~3 seconds.
REPACKING (FIGURE 5)
1. Prior to repacking, the airbag must be fully deflated.
2. To manually deflate the airbag:
a. Locate the Deflate Access Port (5c) near the Fan Housing (5a) near the
mesh on the lower right side of the pack.
b. Locate the round finger-sized Air Release Button (5b) on the end of the
Fan Housing (5a).
c. Press the Air Release Button (5b) to open the valve, then compress the
airbag to squeeze out the remaining air.
3. Locate the Airbag Pocket - Zipper Pull (5d) underneath the Release Flap (1l)
and move it to the opposite side of the pack.
4. Connect the zipper ends together and zip closed while pressing the airbag
into the Airbag Pocket. Distribute the balloon evenly by pressing directly
into the balloon bay and zipping over it. Do not roll or fold the airbag while
stuffing it.
5. Close the zipper all the way to the bottom of the left side of the pack.
A
WARNING! It is imperative that the zipper pull (5d) go past the end of the
short side of the zipper, otherwise the airbag will not deploy . The zipper pull
must be disengaged from the short side of the zipper (see label 5e) .
6. Snap the Release Clip (1k) located on the Release Flap (1l) onto the Airbag
Release Post (1j) and tuck the perimeter of the Release Flap under the sur-
rounding weather shield.
DISARMING THE SYSTEM
There are two stages of manual disarmament:
• Short Term Storage (Sleep) – Less than 7 days without use
• Long Term Storage (Storage) – More than 7 days without use
1. To disarm the system (short term storage) hold the red Power Button (1d)
until the red light begins blinking (~3 seconds), then release the button. No
light indication after the button has been released indicates that the system
has properly powered down.
2. To put the pack in Storage (long term storage), arm the pack per the "ARMING
THE SYSTEM" section of this manual. With system armed, hold the red
Power Button (1d) until you see a red blinking light and then a red solid light
(~10 seconds), then release the button. No light indication indicates that the
system has been properly powered down.
NOTE! There will be a 4-second wake-up delay after the system has been in
storage mode.
3. Store the Deployment Handle (1c) inside the shoulder strap Deployment
Handle Pocket (1b) and zip the pocket closed.
The JetForce BT system also provides automatic disarmament for battery pro-
tection reasons:
• Auto-Sleep: Automatic switch from armed state to sleep mode after 12
hours without movement. The 12 hours timeout can be changed or disabled
(-> Pieps app -> settings).
• Auto-Storage: Automatic switch from sleep mode to storage mode after 7
days or if the battery reaches a critical charge level.
INTERFERENCE WARNINGS
All avalanche beacons are very sensitive to electrical and magnetic influence.
This JetForce avalanche airbag backpack is designed to minimize interference,
but it is the user's responsibility to follow some basic best practices:
A
Avoid carrying unnecessary electronics.
Maximize distance between the beacon and any other sources of electronic,
A
magnetic, and metallic interference (such as phones, smart watches, radios,
heated garments, and electronic airbags).
A
A minimum distance of 20 cm for a beacon in SEND mode and 50 cm in
SEARCH mode is recommended.
A
When in SEND mode, carry the beacon on the front side of your body to
maximize the distance between the beacon and the Jetforce pack inflation
unit.
A
When searching, maximize distance from the Jetforce pack by holding the
beacon in a partially outstretched arm in front of your body.
A
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 50 cm away.
A
All device firmware should be kept current.
A
Refer to your specific beacon manual for interference best practices.
SPECIFIC WARNINGS
A
Disarm the system and stow the Deployment Handle (1c) before riding a ski
lift, tram, airplane, helicopter, snowcat or vehicle and before entering small,
confined spaces.
A
Do not strap anything across the airbag pocket zipper.
A
When the JetForce BT's fan is running, the system may interfere with ava-
lanche beacons.
