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. 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, shorten the
telescoping whip antenna by 2 inches and again check the
indicator. Continue this procedure until the indicator
remains off. If you experience trouble, please contact
COMTEK's application engineering department for
assistance. If you are using an external type antenna, DO
NOT install the telescoping antenna. Instead, connect the
coaxial feed line for the external antenna to the external
antenna port on the back of the BST-25.
Note:
For optimum performance when using the telescoping
whip antenna, the transmitter should be placed on a large
metallic surface. Adjustment of antenna length for a “No
Flash” condition on antenna indicator will ensure maximum
radiation.
