4-5. GENERAL

This section contains a check procedure which you will use to determine if the radio channel control equipment is

operational. This procedure is to be used under the following conditions:

You have received a new radio channel control from a supply facility.

You have received a radio channel control from administrative storage and must check it out.

You wish to periodically check the performance of the radio channel control.

4-6. VOLTAGE MEASUREMENTS

With input power applied, dc voltage measurements can be made as shown in the following tables: 4-1, 2, 3, 4. These

voltages should be present when the power is turned on at S101 of the audio unit assembly and where applicable, under

the specified operating conditions. Illustrations are referred to in the tables to aid in locating the voltage test points. The

measurements can be made using the multimeter.

4-7. RESISTANCE MEASUREMENTS

Certain resistance measurements can be made, as shown in table 4-6, as check on proper operation of the corresponding

circuits. These apply under the conditions given in the table. Use the multimeter. See figure FO-12 to help find the

specified locations.
