Setting the Voltage Range of the PSU
The Power supply fitted to every PSU board used in the system (part number
667/7/22631/000, manufactured by Daren Electronics PLC type PP40-30). An
internal link in this power supply needs to be set for the nominal mains voltage.
See Figure 9 for link setting; set to 110 V position for 98 V to 132 V mains voltage
range, set to 240 V for 198 V to 264 V mains voltage range.

Ensure that the correct variant has been supplied e.g.
666/1/02243/000 for the UK.
666/1/02243/000 or 666/1/02243/001 for non-UK (the /001 variant includes extra
components; metal oxide varistors and gas discharge tubes, for surge protection).
The switches on the Modem PCB should be set as follows:
Note: The tables referred to below contain 0's to indicate open switches and 1's
to indicate closed switches. For all the switches push the switch down to
the left for a 0 and down to the right for a 1. The 0 and 1 position is shown
on the silkscreen underneath switch SW7.
