To activate 2-tone paging - simultaneously press both of

the  volume  buttons  and  hold  briefly  before  releasing.

When 2-tone paging is turned on, the handheld sounds a

"triple  beep".  You  will  only  hear  broadcasts  that  first

send your two unique paging tone.

Note:

It is possible that the beginning of a call might be

missed  while  the  radio  is  in  battery  saver  mode.  If  this

happens, ask the caller to repeat the message.

OPERATION

the channel prior to transmitting.
To  transmit  -  hold  down  the  Push-To-Talk  button  and

with  the  radio  four  inches  away  talk  into  the

microphone.  Speak  in  a  normal  tone,  since  talking

louder will not improve the listener’s reception.
Keep talk times as short and infrequent as possible to

conserve  battery,  minimize  radio  frequency  exposure,

and allow others to use the channel.

RADIO ALERT TONES

The  handheld  responds  to  certain  instructions  by

sounding  a  beep  or  series  of  tones.  These  tones  can

tell you that the radio is working as you expect.

Power  On/Self  Check  “OK”

When  it  is  first  turned  on,  the  radio  runs  a  quick

“self  test”  to  confirm  basic  functions.  When

complete  the  radio  will  emit  the  channel  beep  and

the  Channel  Display  will  show  the  operating

channel.  The radio is then ready to use.

Channel  Scan  Tone

When the Scan channel is selected by pressing the

Channel button,  the radio will emit the Scan beep

and begin scanning.

Squelch  Mode  Tones

When  you  press  and  hold  both  Volume  buttons  at

the  same  time,  a  single  beep  will  sound  to  indicate

that tone squelch is on. A “double beep” means that

carrier  squelch  is  on.  If  the  channel  is  programmed

for  2-tone  paging,  a  "triple  beep"  indicate  that  the

pager has been reset.

Transmitter  Time  Out  Tone

A  low  tone  followed  by  a  higher-pitched  tone

sounds  and  the  transmitter  automatically  shuts  off  if

you  hold  down  the  PTT  button  longer  than  60  sec-

onds.  The  radio  automatically  switches  to  receive

mode.

Recharge  Battery  Alert  Tone

As  the  battery  voltage  approaches  the  minimum

required  “operating  voltage”  the  radio  will  emit  a

series  of  low  battery  tones  to  alert  the  user  that  the

battery  will  soon  need  recharging.  Once  the  battery

charge  drops  below  the  required  “operating

voltage,”  the  radio  emits  a  long,  low  tone  and  turns

itself  off.    If  you  turn  the  radio  back  on,  it  will  beep

again and shut itself off. Recharge the battery.

Error  Tones

If  the  “self  test”  detects  a  diagnostic  error,  an  error

tone  sounds.  The  error  tone  indicates  the  radio

frequency  synthesizer  is  malfunctioning.  Turn  off

the  radio  and  try  again.The  error  tone  will  also

sound  if  a  channel  has  been  programmed  for  an

invalid  frequency.  A  long,  low-pitched  tone  means

the  battery  voltage  is  too  low  to  operate  the  radio.

In  this  case,  recharge  the  battery.  If  you  cannot

correct  a  problem,  consult  an  authorized  Ritron

service  facility  or  Ritron.
