Whenever you suspect that it is unsafe to use
the instrument, you must make it inoperative
by doing the following:
—Disconnect the line cord
—Clearly mark the instrument to prevent its
further operation
Fig. 1-1 Do not overlook the safety instructions!
— Inform your Pendulum representative.
For example, the instrument is likely to be un-

Disposal of Hazardous
Materials
If your instrument was ordered with a built-in
battery supply (Option 23/90), it contains 12
Li-Ion cells arranged as a fixed battery pack
with internal protection circuitry.
Even though this type of cell does not cause
environmental damage in the same way as
NiCd, for instance, you should dispose of a
worn-out battery pack at an authorized recy-
cling station or return it to Pendulum.
Note: Individual cells cannot be replaced.
