This is the bottom side of the shielded version. The shields are on the
right and cover the RF portions. Many..... most maybe.... do not have these
shields. If yours does not, do not fret. They make no significant
difference in practical use.
The space on the lower left is where the battery goes, secured by a piece
of double sided tape or a dab of contact cement. Battery solder tabs are in
the upper left corner.
