Carefully remove the FRG-7 receiver from the carton and examine it for any physical damage.
Should any be apparent immediately notify the carrier stating the damage in detail. Save the carton and packing materials for future use.
The FRG-7 is supplied with a multi-voltage power transformer (export model only) and can be operated in many areas of the world where supply voltage may differ from your local supply voltage. Therefore before connecting the AC cord to the power outlet, be sure that the voltage marked on the rear of the receiver agrees with the local AC supply voltage.
PERMANENT DAMAGE WILL RESULT IF IMPROPER AC SUPPLY VOLTAGE IS APPLIED TO THE RECEIVER.
The FRG-7 will operate satisfactorily from any 1 2 volt, negative ground battery source by connecting the DC power cord (plug is supplied) to the rear panel receptacle. When making connections to the battery, be certain that the inner conductor is connected to the positive (+) and the outer conductor is connected to the negative (-) terminals of the battery. Reversed connection could permanently damage the receiver circuit
The FRG-7 will also operate from eight dry cells in the built-in dry cell pack. (Cells are not supplied ) If the AC supply fails, the dry cell supply is automatically connected to the circuit.
The following Table I shows the power supply combination of FRG-7.
ANTENNA AND GROUND
The antenna is the most important part of the communication receiver installation. The FRG-7 is designed for use with a long wire antenna for 0.5 ~ 1.6 MHz and with a resonant antenna at the operating frequency having an impedance of 50 to 75 ohms for higher frequency than 1.6 MHz. This requirement is easily met by using a center fed dipole antenna resonated to the receiving frequency and fed with coaxial cable.
The FRG-7 should be connected to a good ground. The ground lead should be connected to the terminal marked E located on the rear panel of the receiver.
