STEP 08

Confirm flow

Hold the pen with the needle pointing up. Press and hold the dose button until the counter returns to 0.
A small droplet should appear at the needle tip. If nothing appears, repeat up to 6 times.
If still no droplet, change the needle and try once more. Do not use the pen if flow cannot be confirmed.
