Torque Settings: 
The manufacturer recommends torque setting all power supply terminal screws to a minimum of:
•  1.5 Nm (or 13.28 In/lb or to 1.107 ft/lb)
Note: Dataradio uses a Sturtuvan Richmond 29-pieces adjustable torque screwdriver model
CAL36/4K.
After tightening, pull on the cable to check the cable is secured tightly into the screw terminal.

2.6  Power Amplifier
Although the T809-10 is a high efficiency switched mode power supply, a considerable amount
of heat is generated during normal operation. While in use, ensure that an adequate flow of
cooling air is able to circulate around the power supply, and that the air intake vents on the rear
and sides of the unit are not inadvertently covered.
Caution:
Do not operate this unit in a completely enclosed cabinet.
Connect the T881 Tx module output to the power amplifier’s input using the Dataradio (p/n 727
03468-001) RG223 provided cable.
For the power amplifier output, Dataradio recommends a 50-ohm, low-loss, double-shielded
grade RF cable such as RG214 or 1/4" Heliax. 
Power adjustments can be made using the front panel trim potentiometer. Dataradio does not
recommend setting an output lower than 35 watts.
