XTERNAL ATTERY ACK
The KA018 kit may be powered from either the supplied Castle 12V DC Power
Supply or from an optional external Castle Battery Pack.
To use any external power source simply plug it into the 'Mains / Ext Batt'
Connector on the KA018 case and remove when finished. This procedure will
not interrupt your instruments operation if your batteries are charged and
connected correctly.
The position of the battery isolation switch will not hinder operation with either
the external 12V DC Power Supply or the optional External Batteries, however
the isolation switch will need to be ON for un-interruptible operation between
Internal Batteries and External Supply.
For safety reasons only use the supplied Castle DC Power Supply and optional
Castle Battery Pack.

RINTING
The power switch on the printer can be left on at all times and the printer's
internal battery can be removed when used in a KA018.
With the GA505 printer plugged into the KA018, power is automatically
provided to the printer when data is sent from the instrument. This means that if
the batteries are not installed in the printer or if they are flat, printing will still be
possilbe.
The supplied GA505 printer will operate using the power supplied from your
KA018 kit as with your Pro DX Sound Level Meter. The printer is only powered
when print information is sent to the printer. When the print job is finished the
printer will power down again.
To ensure printing runs smoothly ensure that the power supply and 9 pin D
connector are plugged into the printer.
Printing is achieved via your Pro DX Sound Level Meter, refer to your operating
manual if required.
