4) BASIC OPERATIONS TO BE CARRIED OUT BEFORE USING
YOUR SET FOR THE FIRST TIME (without transmitting and
without using the «push-to-talk» switch on the microphone):
a) Connect the microphone
b) Check the antenna connections
c) Turn the set on by turning the knob (1) clockwise.
d) Turn the squelch knob to minimum (anti-clockwise). Adjust the volume to a
comfortable level.
5) HOW TO ADJUST SWR (Standing Wave Ratio):
With the integrated SWR meter:
Put the unit into AM or FM. Using 12) VFO position the unit in the middle of the
band (you are advised to check the values obtained on the extreme
frequencies, in all cases it is necessary to calibrate). Check that 3) RF POWER
is at maximum.
Calibration:
Press 14) INDIC until a small triangle and CAL appear in the display. Keep the
PPT switch depressed and, using 2) SWR CAL, bring the bar graph to the same
level as the triangle.When you have done this, you are ready to take an SWR
reading as described below.
Reading:
Once theSWR Meter has been calibrated (as above), press 14) INDIC until SWR
appears in the display. Press the PTT switch on the microphone, the bar graph
will show the SWR value. It should be taken from the bottom figures and should
be as close to 1 as possible, a value of above 2 may damage your set
(destruction of the power amplifier).
B) HOW TO USE YOUR RADIO :
1) MODE Switch:
This control is used to select the desired mode: AM, FM, LSB, USB or CW.
The mode chosen must correspond to that of the person with whom you
communicate.
Amplitude modulation/AM: For communicating in areas where there are
obstacles and over medium distances.
Frequency modulation/FM: is used for nearby communications in flat open
areas, and gives better quality communications, but squelch is harder to
adjust.
Lower Side Band/LSB and Upper Side Band/USB: are used for prompt
communications over long distances (depending on atmospheric conditions).
CW : coded in Morse. In order to use this mode, an external key is necessary.
For your comfort, the LINCOLN has an integrated one tone oscillator.
2) SWR CAL:
This control is used to calibrate the integrated SWR meter.
See section 14) INDIC.
3) RF POWER:
This control enables you to adjust RF power continuously aver a range of about
1 Watt to 10 Watt in AM, FM and CW.
When you turn thisknob fully clockwise RF power is at maximum. You should
reduce output power when communicating with someone close by and who
is not equipped with an RF Gain function.
4) RIT:
This knob is used in modes USB, LSB or CW to fine tune the reception signal in
order to obtain maximum clarity. This knob can tune the received frequency
about +/- 2.3 kHz. This control will not effect the transmitting frequency, or the
frequency display, but changes only the reception frequency.
5) ON/OFF - VOLUME CONTROL:
Use this control to turn the unit on or off and to adjust the volume.
6) SQUELCH:
This control is used to suppress undesirable background noise when there is no
communication. Turn the squelch knob clockwise to the exact point where all
background noise disappears. This adjustment should be done with precision
as, if set to maximum, only the strongest of signals can be received. Squelch
does not effect either sound nor transmission power, but allows for considerable
improvement in listening comfort. To use the automatic squelch, turn the
control to the position AUTO (anti clockwise until it clicks).
