USING THE NEWBORN INSERT CUSHION
The Newborn Insert Cushion converts the seat unit into an approved
safe surface suitable for newborn babies.
This accessory can be purchased from Edwards & Co or your nearest
retailer.
The Newborn Insert Cushion should only be used with the seat unit
in fully reclined position. NEVER use the liner in a semi-reclined or
upright position.
To install:
1. Remove the seat unit's shoulder pads and crotch pads.
2. Adjust the shoulder strap height to the lowest position.
3. Thread the shoulder belts through the liner, through the loop on
the back of the head hugger, through the shoulder pads and finally
connect them to the buckle.
4. Pull the lumbar and crotch belts through the liner and connect
them to the buckle.
5. The final installation is pictured below.
