Ritron jbx-151 Betriebsanweisung

The speaker allows you to hear calls on

your channel.  Note that the speaker can

be muted using the squelch control.

The microphone allows your voice to be

heard in other radios.  Hold the radio

about two inches away while talking into

the front grille.  Shouting does not

improve listener reception.

The squelch control knob can mute noise

in the absence of an incoming radio

signal. To silence noise, rotate the

squelch control knob clockwise until noise

first occurs. Then rotate the knob counter-

clockwise to the point that noise stops.

If the JBX unit is equipped with an

RTS-5PA module, you can turn on QC

squelch by rotating the squelch control

fully counterclockwise until the switch

clicks. The radio will then stay quiet until

it receives a call from a unit that transmits

your QC code.

Wait until the channel is free before

transmitting, to avoid interfering with

other users.  Listen for others talking on

the channel by rotating the squelch

control clockwise out of the Quiet Call

click position.

When the PTT button is pressed, the QC

code is automatically transmitted with

your broadcast, independent of the

squelch control setting.

The audio jack can be used to connect

optional accessories, such as a remote

speaker/microphone or an earphone.

NOTE: The remote speaker/ microphone

(RSM-3X) has a two-plug

connector.  Insert the smaller

plug into the charge jack.

This door covers the battery compart-

ment, holding the battery pack in place.

Refer to FIG-2 (page 6) as you continue

reading.

To remove the battery door, unlock the

door latch at the bottom of the radio using

your thumbnail or a coin.  When the latch

is unlocked, the color "red" shows.  Slide

the door away.

To install the door, align it with the battery

compartment (the door’s top edge faces

the antenna).  Place the door against the

compartment and slide the door up, into

the slots shown in FIG-2.  Then lock the

door latch.

See FIG-1, left. Three charger contacts,

visible through the bottom of the radio

case, allow the battery pack to be

charged with an optional RITRON drop-in

charger.  You may charge the battery

pack inside or out of the radio case.

Plug the drop-in charger into an 110 VAC

outlet.  Set the portable or battery into the

charger, three contacts facing down, with

each battery contact resting on a charger

contact pin.

An optional "fast rate" drop-in charger unit

charges the standard battery in less than

two hours.  For a list of optional battery

chargers, refer to the "Accessories"

section (page 9).

Make sure the battery is installed correctly, as shown in

FIG-2 (pages 6).

Recharge or replace the battery.  (See note 1 on the

Move to a different location. (Note 2.)

Rotate the squelch control fully CW, then CCW to

the point that noise disappears.  (Note 3.)

Adjust the squelch control as stated above. (Note 3.)

Confirm that your portable is equipped with a Quiet Call

module.  (Note 7.)

Program your Quiet Call module with the same code as

the calling radio(s) use.  (Note 7.)

Verify that your portable is equipped with a Quiet Call

module.  (Note 7.)
