SECTION II - OPERATING INSTRUCTIONS
1.
Turn the power on by turning the VOLUME control clockwise.
2.
Check the metre indicator for battery condition (See Section III-C),
3.
Connect the antenna system to the SBX-11A ANT and GND terminals per drawings in
antenna section.
4.
When using a fixed tuned type of antenna, the CHANNEL and antenna frequency must
correspond.
5. To
receive, adjust the VOLUME and CLARIFIER controls for the desired volume
and
maximum speech clarity.
6. To
transmit, press the microphone button and talk from a distance of about two inches into
the microphone. Do not shout. Power output will be indicated by the metre needle
swinging to the right.
7.
If the antenna is of the tuneable type it must be tuned to the channel frequency selected.
Each time a different channel is selected by the CHANNEL switch the antenna must be
retuned to the new frequency.
8.
To tune the antenna use the following procedure:
a) Select the desired channel.
b) Press the TUNE button while quickly tuning the antenna for
maximum POWER OUTPUT indication on the metre.
IMPORTANT
When tuning the antenna the SBX-11A is delivering a continuous high
level of power and during this period the consequent battery drain is several times higher
than in ordinary SSB operation. To avoid unnecessary battery drain keep the transmitter
‘ON’ only as long as is absolutely necessary for antenna tuning.
9. CAUTION
Always turn the power off at the volume control before replacing the cover of the SBX-11A
for transportation. Failure to do so will discharge the batteries.
