Always insert the UP-F04RB/UP-P02MB with its upper side directed
upwards (The upper side of UP-F04RB/UP-P02MB is the same side
as the notch of the connector part).

Install and remove the UP-F04RB/UP-P02MB as follows:
Handling the UP-F04RB/UP-P02MB forcibly may break the connector
lever.

1) Insert the terminal side of UP-F04RB/UP-P02MB into the connec-

tor with the parts face upwards.

Push the center part of UP-F04RB/UP-P02MB’s PWB onto the
upper slot at an angle of 30 to 40 degrees or onto the lower slot at
an angle of 45 degrees against the main PWB to insert until it hits
the back of the connector.

2) Grab the UP-F04RB/UP-P02MB’s PWB on the center part to push

down by sliding on the arms of the connector’s both sides using
the PWB’s terminal side as an axis until the arms click.

If the arms are too hard to push the UP-F04RB/UP-P02MB down
smoothly, push the UP-F04RB/UP-P02MB down from above with
opening the arms of the both sides of the connector right and left
using your fingers.

1) Open the arms of connector’s both sides using your fingers.

2) Check that the arms of the both sides are off and the UP-

F04RB/UP-P02MB stands at an angle of 30 to 40 degrees on the
upper slot against the main PWB or at an angle of 45 degrees on
the lower slot against the main PWB.

For the lower slot, the UP-F04RB/UP-P02MB may be caught in
the arms of the upper slot and stopped on the way to stand up.
Check that the UP-F04RB/UP-P02MB stands up to about an
angle of 45 degrees by further opening the both arms of the upper
slot right and left.

3) Pull the UP-F04RB/UP-P02MB out of the connector along the

inclination with which the UP-F04RB/UP-P02MB stood up.
