13) Output Adjustment Volume : Adjustment Volume for output voltage. It is
factory-present at the optimum
level. When the modulation level is not acceptable to you, please adjust this
volume to have optimum level.
(Please adjust under the
“
HIGH
”
position of Compressor Level Selector
Switch.) The Output is increased by rotating the volume⑬ clockwise. Please
adjust with 2mm wide screw driver carefully and slowly under monitoring by
local station. (It is relatable 90゜ for both left and right from center position.)
The Figure No. 3 shows the center position.
14) The Leadwire releasing for the Non-Modulation Prevention Circuit.
15) Battery Cover
: When operating with battery, remove the 2 set screws of rear side(bottom
plate) and set the batteries (2 × UM3) correctly. The batteries are not
provided with this microphone.
(Optional Accessories
: External Power Supply Adaptor model PS3 will
enable you to use with DC13.8V external power
supply unit. Please note.)
NON-M:ODULATION PREVENTION CIRCUIT:
When the transmitting condition continues for 2-3 minutes, the alarm circuits will be activated with sounding the
alarm for 30 seconds. Then, the condition will return to the receiving condition automatically.
(Timer Reset Function)
When using the microphone with
“
LOCK
”
(continuous transmitting), press the
“
LOCK
”
switch again and the
timer for alarm will be reset and the timer again starts for counting. When sounding the alarm, the alarm will stop
by pressing
“
LOCK
”
switch.
CANCELLING OF NON-MODLTLATION PREVENTION CIRCUlT:
Remove the battery cover ⑮ and cut off the leadwire ⑭ yellow which is the wire for canceling the
Non-Modulation Prevention Circuit. After cutting, please be sure to cover the wires (tip of wire) with insulation
tape.
COMPRESSOR AMPLIFIER FUNCTION:
Compressor Amplifier serves constant distortionless
output level regardless of the audio input level
conditions. In other words, depending on the audio input
level, electrical volume control is automatically made.
Please refer to the sketch below. The input levels from
‘
a
’
to
‘
b
’
are linearly amplified and from
‘
b
’
to
‘
c
’
are compressed. The compressor level means the
voltage ratio of input levels at
‘
b
’
and
‘
c
’
. For
example, at compressor
“
HIGH
”
, compressor area
Includes from 1mV and it has 45dB compressor Level
minimum. So, you can send out the constant output level regardless voice, whispering, small or loud. By the
constant output level, you can extend the communication distance by using rated output power of transceiver
without any loss. So, now it becomes common to use compressor amplifier between transceiver and microphone.
CAUTIONS :
Please be sure to use
“
ADONIS
”
Interconnecting Cables separately available.
Please refer to the list of Microphone Cables.
When supplying the power from transceiver with
“
D
”
type mic. cables, the batteries set to the microphone
do not send the power to microphone, but, after switching the power
of transceiver
“
OFF
”
, the
batteries in the microphone will be activated automatically. Please be careful about it. Please
be sure to turn the power switch
“
OFF
”
after QSO.
When using external adaptor for power supply from DC13.8V, please be sure to use PS-3 optionally available.
Please be careful about high SWR of antenna and incomplete earthing, since it may cause the trouble of RF
Feedback noise depending on coaxial cable layout.
Do not place the microphone near high temperature area or under direct sunlight.
