Important notes on MX8000-3EX
The MX8000-3EX Receiver is only intended to operate on 220-240VAC, 50/60 Hz
The clock synchronization may be needed to be set to match the power line frequency. It may be set to 50 Hz, 60 Hz, or
Internal. Internal may need to be used if the power line frequency in the installation site is not stable. Frequency instability
will cause drifting of the time and date.
See Section 5.3.4.1 and Table 5-9 for information on setting the synchronization method.
Depending on the country of installation, the phone line characteristics of the MX8000 may need to be adjusted. This may be
done by setting the Country Code, as shown in Section 5.4.2.3. The choices available are:
Brazil
Australia
CTR21
USA
South Korea
South Africa
Poland
Philippines
Bulgaria
