INSTRUCTIONS FOR USE – KEEP INSTRUCTIONS FOR FUTURE REFERENCE
JETFORCE BT BACKPACK INTRODUCTION
The JetForce BT Backpack is designed for use in and around areas with the chance
of snow avalanches. This backpack incorporates the JetForce Avalanche Airbag
System, which is designed to improve the chances of surviving an avalanche. By
increasing the total volume of the person caught in the slide the airbag helps keep
the victim on the surface, decreasing the chances of a complete burial and allowing
for a faster rescue.

SYSTEM FUNCTION
When the airbag is deployed by pulling the Deployment Handle (1c), the Release Clip
(1k) is forced open, allowing the Release Flap (1l) to open, and then the inflating air-
bag opens the airbag zipper. The airbag can then fully inflate (Figure 2).
SELF-DIAGNOSIS
To ensure that your JetForce BT Avalanche Airbag will function properly, the
JetForce BT electronic system performs a comprehensive self-diagnosis on every
system startup. The system checks the battery charge level, motor and fan opera-
tion and all critical electronics such as status lights,
trigger electronics and the battery electronics. The system also performs frequent
diagnosis while armed. A properly working system indicates a pulsing green System
Status Light (1e), located on the Deployment Handle (1c). Warnings/malfunctions are
indicated with a red System Status Light (1e), in conjunction with the blue Charge
Status Lights (1f). Refer to Troubleshooting section of this manual for details.

WARNING
BATTERY CHARGING
Always make sure the system has a full charge before heading out into avalanche
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 (0°C to 45°C / 32°F to 113°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

• 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 protec-
tion 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.
