Operating Procedure; Preparation; Call - JRC JHS-7 Instruction Manual

(10) Tx lamp
Lights red during press-to-talk operation.
It monitors the transmission output. If the Tx
lamp does not light even when the PTT button
is depressed, the transmission circuit may be
faulty.
(11) PWR/VOL (power switch/volume) control
Works as power switch and volume control.
Turning the PWR/VOL control fully
counterclockwise turns off the power. Turning it
clockwise turns on the power. Sound volume
increases as it is turned clockwise.
(12) BUSY lamp
Lights green while the squelch is open. It also
monitors the battery condition. When the
battery is almost consumed, the BUSY lamp
blinks for warning.
(13) 16(CH16 indicator)
Lights orange when CH16 is selected. This
lamp also monitors the condition of the internal
frequency synthesizer. The 16 indicator blinks
if the frequency synthesizer has any trouble
(unlocking).
(14) CH16 switch
A toggle switch for CH16. Setting it to the 16
position selects CH16. Setting it to the CH
position selects the channel number specified in
the following subparagraph (16).
(15) Background illumination for a channel
number
Illuminates to enable easy reading of the
channel number selected the following
subparagraph (16).
(16) Channel setting switch
Use this switch to select other CHs when the
CH16 switch is set to the CH position. The
speaker makes alarm buzz when no
preprogrammed channel is selected.
(17) SQ(squelch) control
Turning it fully counterclockwise opens the
squelch. As it is turned clockwise, higher input
level is reguired to open the squelch.

3.2 Operating Procedure

3.2.1 Preparation

(1) Set a desired channel number.
(2) Turn the squelch control fully
counterclockwise.
(3) Turn the PWR/VOL control clockwise.
Just after the power is turned on, noise is
heard from the speaker. Adjust sound
volume properly by turning the PWR/VOL
control.
(4) Turn the SQ control until noise from the
speaker is suppressed. Turn the SQ control
a little clockwise from that position. Do not
turn it too much, because the squelch will
not open when a weak signal is received.
Thus, radiotelephone is in stand –by mode,
and ready for reception.

3.2.2 Call

(1) While holding down the PTT button on the
left side of the radiotelephone, call up the
partner station (called Station A for now).
(Depressing the PTT button lights up the
Tx lamp.)
Calling is performed as described below.
Example:
"Station A, Station A, this Station B.
How do you read please."
Release the PTT button to set the
equipment ready for reception as soon
as this call is over, and wait for an
answer from Station A.
Station A may reply in such a manner
as shown below;
"Station B, Station B, this is Station A,
I've gotten you, please."
Since this radiotelephone employs the
press-to-talk communication system,
only one-way message is available.
Therefore, with the aim of smooth
conversation, it is preferable to insert a
word "please" or "over" at the end of
each speech as shown in the above
examples before releasing the PTT
button.
