d. Plug the adaptor into a standard AC outlet and plug
the power connector into the DC input jack of the
transmitter. Turn the display switch on the front of the
transmitter "ON" to allow monitoring of the transmitter
frequency. Turn the main power switch on the front of the
base station to the "ON" position. The front display should
now be illuminated.
e. Mount the telescoping whip antenna in the hole on
top of the base station rotating it clockwise until it is firmly
seated. Extend the antenna completely (12 1/2 inches).
During normal operation the antenna indicator should not
flash. Turn on the transmitter and verify that the antenna
indicator is not flashing. If the antenna indicator is
flashing, it is an indication that the antenna is not fully

length, antenna elements in too close proximity to metallic
objects, or for a damaged coaxial cable to remote
antenna. Also, DO NOT install screw-in whip antenna if
remote antenna is used.
