x
Ensure that for amplifier models with multiple line-input connectors, all connectors
are connected to the line supply.
x
Ensure that for models with more than one power supply, that all the rear panel
circuit breakers are set to the ON position.

Note:
If the supply fault indicator is due to a high-temperature condition,
cool the
power-supply by
leaving the amplifier in, “
STANDBY
”
mode. The power-supply
cooling fan (internal to the power-supply) can then reduce the power-supply
temperature. If the supply fault indicator remains illuminated when the power-supply
has cooled down, return the amplifier to TESEQ for repair.
Thermal Fault
A thermal fault is indicated on the display in the amplifier fault section when the
temperature of the modules has risen above operational limits.
x
Ensure that both rear panel fans are operating and not obstructed.
x
Ensure that the air-filter inserts are not clogged or obstructed. Clean or replace if
necessary.
x
Ensure that the amplifier is not operating in direct sunlight.
x
Ensure that the ambient temperature is within the amplifier specification.
x
Ensure that there is at least the recommended clearance around the front and rear
panel air vents.

Note:
To cool the RF modules down, leave the amplifier in the RF STANDBY
condition so the cooling fans can reduce the RF module temperature. If the fans are
not operating, or this indicator remains illuminated when the RF modules have cooled
down, return the amplifier to TESEQ for repair.
If, after fault-finding, problems persist, contact TESEQ by telephone, fax or E-mail. It
may be necessary to return the equipment to TESEQ for repair. See the Appendix 2
for details on how to do this.
