2.1.2 SC-30 power supply
Before you turn the SC-30 on, the first thing you must do is connect it to a battery or other
power supply. Note: The components referred to in the text are indicated on the outline on
page 7 and listed in parenthesis, e.g. [
13]
The SC-30 sound level meter is fed by a 6LF22-type alkaline or lithium battery or by direct
current [
14]. For DC supply use the A-200 model mains feeder. If both systems
are used at the same time, the SC-30 selects the one offering the higher voltage. The
maximum permitted input voltage is 12.0 volts. This means a “12 V” car battery should only
be connected to the SC-30 through the A-101 converter
as such a battery can be up to 14 V.
To fit the battery, raise the battery compartment lid [ 11]
at the rear of the SC-30. Put the battery inside and press
it down until it clicks into place (see figure).
When the battery is insufficiently charged to allow the
SC-30 to work properly, a battery icon appears in the
bottom right-hand corner of the sound level meter screen
(see figure).
