light. LCD brightness or
contrast is improperly

for more than 10 seconds as
power is applied. The LCD
brightness and contrast are set to
their default values.
Check Network Wiring
Use the Right Wire In order to ensure optimum performance over the full range of your installation
topology, Crestron Certified Wire, and only Crestron Certified Wire, may be used.
Failure to do so may incur additional charges if support is required to identify
performance deficiencies because of using improper wire.
Calculate Power
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do
so could cause equipment damage or void the Crestron warranty.
CAUTION: Provide sufficient power to the system. Insufficient power can lead to
unpredictable results or damage to the equipment. Please use the Crestron Power
Calculator to help calculate how much power is needed for the system
(
http://www.crestron.com/calculators ).
When calculating the length of wire for a particular Cresnet run, the wire gauge and
the Cresnet power usage of each network unit to be connected must be taken into
consideration. Use Crestron Certified Wire only. If Cresnet units are to be daisy-
chained on the run, the Cresnet power usage of each network unit to be daisy-chained
must be added together to determine the Cresnet power usage of the entire chain. If
the unit is a home-run from a Crestron system power supply network port, the Cresnet
