external equipment instruction manual).

Power requirements

An external 12V to 24 DC or 24V AC supply with 100mA capacity (not supplied) is required / available
from most high street electrical retail outlets. Some DC adaptors are supplied with a plug already
attached these will need to be removed. Important that you careful check to ensure correct +/- polarity
