F.  Using Holster

Three different ways to use holster:
1.   Set holster parallel on the table, do not open
      the tilt stand (see diagram 1)
2.   Set holster in a small angle on the table, tilt
      it up by the first part of tilt stand (see diagram 2)
3.   Set holster in a large angle on the table, tilt it
      up by all two parts of tilt stand (see diagram 3).

G.  Using Strap

1.   Put the front end of the strap through the round
      metal of the Meter, see part 1 of the below
      diagram.
2.   Put the bottom end of the strap through the
      front part and tide it up, see part 2 of the below
      diagram.
