Operating Instructions
(1) If the ac POWER MODULE is installed, disconnect the ac power cord from
the module, remove the power module from the receiver, and select the desired ac
operating voltage (i.e., 115 or 230 Vac, nominal) by means of the voltage-selector
switch on the circuit board in the ac POWER MODULE.
Check the value for the installed fuse and change if necessary. Install the ac
POWER MODULE in the receiver and secure by means of the captive fastener
screw provided. Connect the ac power cord to the ac POWER MODULE. Plug
the power cord into a wall ac power outlet.
(2) If the BATTERY POWER MODULE is installed, remove the power module
from the receiver and verify that four fresh “D” cells have been installed into the
BATTERY POWER MODULE. Install the module into the receiver and secure
with the captive fastener screw provided.
WARNING: If the BATTERY POWER MODULE is installed, do not apply
external dc, damage to the module may result. No damage will be done to the ac
module if dc is applied.
Note: If external dc is used, it must be in the 13.0 to 20.0 Vdc range. Below 13.0
Vdc, performance may suffer due to loss of regulation; above 20.0 Vdc, the
internal regulator may overheat and shut down.
(3) Connect the antennas. If whip antennas will be used, they should be connected
directly to the recessed BNC antenna connectors on the rear panel.
(4) If Vega cable-connected antennas are used, connect each of the two cables to
the antenna connectors. Mount/attach the two antennas to the structure to be used
to support them. Do not mount antennas so that the “active” part of the antenna is
located near metal surfaces. (See section on antennas below.) A vertical
orientation is recommended; however, there will be no great difference in
performance if horizontal mounting is necessary. Antenna-to-antenna distance is
not critical; however, at least 6 inches (0.15 m) is recommended. For further
information on proper antenna placement, see the following paragraphs.
(5) Plug the audio cable into the rear-panel audio output connector on the receiver
and connect the opposite end to your audio equipment (mixer console, PA
amplifier, etc.).
The receiver output is a standard, transformer-isolated, balanced configuration.
(6) Select the desired audio-output range for the receiver on the rear-panel
“MIC/LINE” switch. The “LINE” position corresponds to the usual line level, and
“MIC” corresponds to typical microphone levels. Be sure that the receiver output
level is not higher than that which can be accepted by the audio equipment
connected to the R-662A output jack. If you have not already done so, verify that
the transmitter frequency matches that of the receiver.
