Lift up the locking tab and open the battery compartment cover. Insert the AAA
battery oriented according to the marking on the HUD. Close the cover and install
the screw. Gently tighten for even gasket pressure ensuring a good seal. Do not over
tighten the screw. Repeat for the second battery on the other side.
When closing the battery compartment the HUD will ash all LEDs two times.
2.4 HARNESS ADJUSTMENT
The harness should be adjusted to ensure that the majority of the weight is carried
on the hip, not on the shoulder. To accommodate for different body sizes the height
of the harness can be adjusted by altering the distance between the hip belt and the
shoulder harness.
To adjust the harness push the two red buttons located beneath the hip belt together.
Slide the hip belt up or down until it clicks into the correct position.
There are four different positions, S, M, L and XL. The selected position is indicated
with red squares next to the letters “S”, “M”, “L” and “XL” engraved in the backplate.
The size indication is visible from both sides of the harness.
The height adjustment can be made with cylinder mounted and also with SCBA
installed in a re truck.
2.5 MOUNTING THE CYLINDER
1. Make sure the hoses are routed correctly according the picture. In the correct
position the raised area showing “INTERSPIRO” on the hose connector is visible
in the cut out of the locking plate. Secure the locking plate by tightening the
screw.
