INITIATING A CALL
(Default is Automatic Turn-Off)
•
Press and HOLD the PTT button to talk.
A unique Call Tone will be sent to radio-equipped personnel when the
PTT button is pressed. The Call Tone is also heard on the speaker at
the RDC-1.
•
Begin speaking after the beep.
The caller should be 3 feet or less from the microphone.
•
Release PTT button to listen.
RECEIVING A CALL
•
Any return call from a radio will then be heard on the RDC-1 speaker.
NOTES:
•
If a return call is not received within 10 seconds of releasing the PTT
button AND, there is no additional radio activity on the channel
(the
Inactivity Rest Time Default is 10 seconds),
t
he speaker on the RDC-
1 will sound a hi/low double-tone and then the speaker will turn off
automatically.
•
If ENABLED (DoorCom
™
Time-Out Tone), the same distinct tones will
be transmitted to radio-equipped personnel to signal that the speaker
has turned off and internal communications can continue.
•
No calls from radio-equipped personnel will be heard on the RDC-1
speaker. Pressing the PTT button on the RDC-1 again will turn the
speaker on and will resend the Call Tone.
The Automatic Turn-Off feature is designed to prevent eavesdropping at
the RDC-1 speaker.
System Range and Coverage
The typical range of the DoorCom
™
system is defined as: 1 floor,
350,000sq. ft.. Coverage depends on building structure and/or
surrounding typography. Concrete walls, steel, metal shelving, racks, etc.
can further reduce your coverage.
Site Survey:
Before permanently installing the DoorCom
™
system, we
recommend that you conduct a site survey to determine the actual radio
coverage in your facility.
1. You will need two people to conduct the site survey: One person to
operate the DoorCom
™
system, the other person to walk the facility
with a compatible portable 2-way radio.
2. Temporarily position the DoorCom
™
system in or near the location it
will be mounted. Note: Locating the radio transceiver with antenna as
close as possible to the desired mounting location is critical to an
accurate site survey.
3. Apply power to the DoorCom
™
system and initiate a call to the other
2-way radio. Continue the conversation while the person with the
portable radio moves to a variety of locations in the facility.
4. If you are unable to achieve the desired coverage:
A. Try mounting the radio with the included antenna slightly higher.
Keep in mind the included connecting cable that connects the
radio to the external speaker intercom box is only 20ft in length.
B. If this is not successful, we offer the optional RAM-1545
magnetic mount antenna with a 25ft cable. This will allow you to
locate the antenna separately from the radio.
RADIO ALERT TONES
The radio 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 power is applied to the radio, the radio will run a
quick “self test” to confirm basic functions. When
complete the radio will sound the Channel Beep and the
Channel Display will show the operating channel. The
radio is now ready for use.
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 with an invalid frequency.
A long, low pitched tone means the supply voltage is too
low to operate the radio. If you cannot correct the
problem, consult an authorized Ritron
service center or
Ritron directly.
Transmit Time-Out Timer –
(Default is 60 seconds)
If the PTT is pressed longer than the programmed
Transmit Time Out Timer time period, a low-tone
followed by a higher-pitched tone sounds and the
transmitter automatically shuts off.
OPTIONAL PROGRAMMABLE RADIO ALERT TONES
DoorCom
™
Time-Out Tone –
Default is Enabled (FP)
If ENABLED, a distinct hi/low double-tone will be heard
on the speaker of the receiving portable radios. This
tone alerts radio-equipped staff that the DoorCom
™
speaker has turned OFF and internal communication
can now continue.
Courtesy Beep –
Default is Not Enabled – Requires PC
At the end of each received transmission, a short tone
will sound only on the RDC-1 speaker. This indicates
that the channel is clear and you may now transmit.
Busy Channel TX Inhibit –
Default is Not Enabled –
Requires PC
When the PTT is pressed and another radio is
simultaneously transmitting on your radio frequency
without your tone, the radio will beep a series of long,
low tones (like a telephone busy signal) and you will not
be allowed to transmit.
Transmit Clear To Talk Beep –
Default is Not Enabled -
- Requires PC
After the PTT has been pressed a short tone sounds on
the RDC-1 speaker. This indicates that the radio is ready
for you to begin talking.
