7. Exchanging frontplates
Apply gentle pressure to the transparent cover as shown in
Fig. 3 until pops out on the opposite side. The label in the
cover can be replaced and used for notes.
After replacing the label in the transparent cover, the trans-
parent cover can be snapped into the front of the device
again. This is done by inserting it behind the edge at the
bottom and pressing it gently down and to the rear with the
finger until it snaps into place (right side of Fig. 3).
8. Withdrawing and inserting the device
Fig. 4
Insert the withdrawing handles (2) into the openings (10) until
they snap into place. Withdraw the front part together with
the main PCB out of the housing.
To reassemble the unit, insert the front part together with the
main PCB into the housing until the swallow-tailed sections
engage in each other.
