OPERATING INSTRUCTIONS
6.1.
PREPARING THE INSTRUMENT FOR USE
For safety reasons, the instruments purchased with the battery leave our warehouse with the
connector-terminated lead of the battery disconnected.
It is therefore necessary that the buyer, before using the instrument, reconnects it. This operation
may be carried out by simply removing the instrument from its bag, and unscrewing the four
fixing screws to take off its cover (see Figure 2). Connect the female connector of the battery to
the male connector which is bolted on the printed circuit board of the generator, secure the cover
back in place using the four screws, then put the generator back into its bag.
