Switch the transceiver on by turning the Volume control clockwise
until the indicator lamp lights.
Select the required Channel and USB or LSB mode.
If using a broadband or dipole antenna go to step 5.
After selecting the required channel:
(i) Where a multi-frequency tapped whip is used, select the correct
tap position for the frequency in use.
(ii) Where an automatic antenna tuner is used, select Tune for
approximately one second and ensure the "tune complete",
double high beep is heard.
(iii) Where a manual antenna tuner is being used, set the tuner
controls to the logging scale positions. Before transmitting
operate the Tune switch and adjust the Tune control on the
front panel for maximum meter reading.
With the Mute switch in the Off position, set the Volume control to a
comfortable listening level. The mute function removes background
noise when no signals are present and should be switched Off to
prevent occasional loss of syllables when communicating in the
presence of weak signals.
Adjust the Clarifier to obtain a better speech quality if necessary.
Listen before transmitting to ensure that the selected Channel is free
of traffic.
Hold the Microphone side-on, close to the mouth. Press the
Transmit button and speak clearly.
When transmitting, the Indicator light will flicker. Tune will cause the
Indicator to light continuously.
Audible tones are provided to inform the operator of equipment status
or provide an operating error warning as shown in Table 3.1.
