1.2 Equipment Safety

1.2.1 Installation and Servicing Personnel

The equipment should be installed and serviced only by qualified

personnel.

1.2.2 Preventing Damage to the PA

The repeater has been designed to operate safely under a wide range of

antenna loading conditions. Transmitting into a low VSWR will maximize

the power delivered to the antenna.

Notice Do not remove the load from the TB7304 while it is transmit-

ting.

Load transients (switching or removing the load) can damage the PA output

stage. See MBD-00001-xx TB7300 Installation and Operation Manual,

especially section 5.4, for recommendations.

1.3 Environmental Conditions

1.3.1 Operating Temperature Range

The operating temperature range of the equipment is –22°F to +140°F

(–30°C to +60°C) ambient temperature with external DC, battery isolated,

or –22°F to +122°F (–30°C to +50°C) ambient temperature with internal

battery and AC input.

Note Ambient temperature is defined as the temperature of the air at the

intake to the cooling fans.

1.3.2 Humidity

The humidity should not exceed 95% relative humidity through the

specified operating temperature range.

1.3.3 Dust and Dirt

For uncontrolled environments, the level of airborne particulates must not

exceed 100µg/m
