DigiWave 300 Series Digital Transceiver and Receiver
System Overview
The Digi-wave™ system is a patented, digital spread-spectrum (DSS), simultaneous two-way wireless listening system
operating in the 2.4 GHz band. Due to it’s frequency-hopping algorithm, it avoids interference and is a very secure method of
communication. For a more detailed explanation of how Digi-wave technology works, please visit our website and download the
“Digi-wave™ Technology White Paper” (under “Support – Downloads - Tech Bulletins”).
A Digi-Wave communication system consists of at least one transceiver (DLT 300 ) and various combinations of transceivers and
receivers (DLR 360 ) depending on the venue.
The DLT 300 is a 2-way transceiver, meaning that it can transmit and receive audio simultaneously. It can operate in one of 3
dierent modes:
1. In Two-way Mode, a speaker (with a DLT 300) can hear another speaker’s voice (from a second DLT 300) and, at
the same time, can also transmit their own voice. In this way, two-way communication is established (similar to a phone
conversation). Two-way mode can only be established between DLT 300 units. In addition, DLR 360 receivers in the
same group can also hear the broadcast.
2. In One-way Mode, one DLT 300 acts as a transmitter (speaker) and another DLT 300 acts as a receiver (listener). In
addition, DLR 360 receivers in the same group can also hear the broadcast. There are 4 one-way modes.
3. In Repeater Mode, the DLT 300 receives audio from another DLT 300 and re-broadcasts the signal to increase the
transmitted range of the person speaking. In this way, larger groups can be covered by using one or more DLT 300’s
acting as repeaters. Listeners can have either DLT 300’s or DLR 360’s to listen to the broadcast.
4. In Intercom Mode, up to six people can talk simultaneously. All of the DLT 300’s are in 2-way mode in the same
group. More DLT’s can be in the group, but only six can have live mics at the same time (the seventh DLT who wishes
to speak pushes their TALK button and knocks the sixth talker o). DLR’s can listen-in on the conversation if desired.
The Repeater function only operates in 1-way mode. It is not available in a 2-way scenario.
The DLR 360 is a receiver only. Users of receivers can only hear what is being broadcast by DLT(s).
Combinations of one or more DLT 300’s and DLR 360’s in One-way mode, Two-way mode, or Repeater mode can be used to
facilitate dierent events, depending on what needs to be spoken and what needs to be heard. Examples of scenarios will be
covered here.
Typical Scenarios include:
Guided Tours - with one or more tour guides (2-way), with audience participation (2-way), or without audience participation (1-way)
Language Interpretation - one or more interpreted languages transmitted to audience (1-way)
Intercom - with up to six people able to speak simultaneously (2-way)
Note: there are many more scenarios than are covered in this manual, however these would be variations on the ones discussed
here. Rules of Operation for 1-way or 2-way mode must be followed for successful operation.
Note: for simplicity, throughout the rest of this manual, the DLT 300 may be referred to as a “DLT” and the
DLR 360 may be referred to as a “DLR”. Similarly, Master 1, Master 2 and Guest may be referred to as “M1”,
“M2”, and “GST”.
The Digi-Wave 300 Series is not backward compatible with previous Digi-Wave
transceivers or receivers.

Getting Started: Preprogrammed Systems
If a system has been purchased, you should not need to perform any programming. The system will have been congured to your
order. Turn Master 1 on rst so other units can pair. Guest units will turn o after 5 minutes if they cannot nd a master.
1. Charge all DLTs. If using DLRs, either charge them with NiMH batteries or insert fresh Alkaline batteries. Make sure the battery
switch is in the correct position for “Alkaline” or “NiMH”. Any DLRs that will be used should have fresh batteries.
2. Identify and turn on the Master 1 rst, usually identied by a grey silicone cover. Turn on the DLT by holding the power button
until the LCD screen comes on. If Master 2 or Guests are powered up rst they will turn o after a few minutes if not paired
with the M1. As Master 2 and Guests are paired with the M1 the M1 and M2 will show C-#. The # refers to how many DLTs are
paired within the group, i.e. C-12 means that 12 DLTs are paired with the M1 or M2 within their group. This can be utilized as
an attendance checker making sure everyone is connected with the group.
3. Once all the DLTs are on, you can check the set-up status of all units by pressing the power/menu button momentarily to scroll
through the settings:
Master 1 and Master 2 screens will display:
C-6 (Chairman plus six = number of participants within the group).
ADD Address number (0 – 1023). Each DLT must have its own individual address.
Group number (0 – 1023) must be the same number for the group.
CODE Only shows if a code has been entered (code number will NOT be displayed).
“F-#” Denotes software version.
Time Displays the time of day.
All Guest units will display:
Address Number
Group Number
Secure Key Code (if entered)
Software Version
Time of Day
4. If headsets are to be worn, plug them into the jacks on the top of the DLTs making sure that the Microphone and Earphone
plugs are fully inserted into the correct jacks.
5. The Master 1 will usually be the rst speaker and should press the talk button momentarily to activate the microphone. This will be
conrmed by the red LED around the talk button illuminated. If the talk LED is ashing, the talk button was held too long and the
talk mute has been activated in the system. Hold the talk button until the LED’s stop ashing to deactivate talk mute.
6. The Master 2 and all Guest units should now be hearing audio from the M1 unit. Listening volume levels can be adjusted by
pressing the – or + button. One other DLT can activate the Talk button for team tour or teach applications. A maximum of two
talkers can be activated at any one time. For a Guest unit to talk, either the M1 or M2 will have to turn their talk button o by
quickly pressing their talk button.

DigiWave 300 Series Digital Transceiver and Receiver
Before Programming the Digi-Wave™ System
Depending upon the mode chosen, up to six people can talk in a group at any given time. The M1 will have rst priority, M2 has
second priority and Guest units have third priority. When two or more people are talking in a group, the participants can hear their
voices with the DLTs or DLRs.
The M1 and M2 have the ability to lock out other talkers by holding down the TALK button for three seconds. All system TALK
LEDs will continuously ash while other participants are locked out of the TALK feature.
There are 4 basic steps to programming a Digi-Wave system.
1. Decide which mode you need.
A. 2-Way Modes
In 2-way mode, DLTs can hear and talk to each other, just like having a phone conversation or a conference call. DLRs can
listen to the conversation. Common applications include: Tours with multiple Tour Guides, Tours with audience participation
(Q&A), Wireless Intercom, Portable Discussion and Personal Communication.
There are two 2-way Modes represented by these symbols on the LCD Display:
2-way:
(4 simultaneous talkers maximum)
2-way - Intercom:
Rules of Operation (2-way modes)
The following rules must be followed. Failure to adhere to these rules will result in unpredictable, unsupported operation.
• There must be one, and only one Master 1 (M1) per group.
• If the M1 unit is o, the Master 2 and Guest units will turn o after a few minutes.
• Master 2 is optional and there can only be one per group.
• Each DLT must have its own address and the address cannot be duplicated within a group.
• Maximum 4 talkers (in 2-way mode) or 6 talkers (in 2-way Intercom mode) can operate simultaneously within a group.
• Maximum four Groups can operate simultaneously within the same area, but each group must be assigned its own group
number.
• When using four simultaneous groups, group numbers must be sequential. i.e. 11, 12, 13, 14. Any numbers 0-1023 can
be used (or 0-99 if DLRs are used in the system).
• Attendee count will only work with addresses 1-99 (Maximum 100 DLT’s with one Master 1 at address 0).
• With Secure Key Code active, all DLTs within the group must have the same 4-digit code entered. (DLRs will not work
with secured DLTs)
B. 1-Way Modes
In 1-way mode, communication ows in one direction. It ows from the main speaker’s DLT, to secondary DLTs or DLR’s. If
repeater mode is used, the repeater DLTs listen to the primary DLTs and transmit to DLTs and DLRs assigned to the same
Group/Channel. The most common applications are: Simultaneous Interpretation with one or more interpreters, or Tours
without audience participation (no Q&A).
(6 simultaneous talkers maximum)
There are (4) 1-way Modes represented by these symbols on the LCD Display:
1-way - Main Speaker:
1-way - Interpreter:
1-way - Repeater Mode:
1-way - Listen Only:
(talks on Channel 0)
(receives on Channel 0, speaks on Channel designated for their language)
(Units out of range of the primary unit(s) receive their broadcast from these units)
(receive the broadcast from either the primary units or the repeater units, depending on range)
9
Page 10
DigiWave 300 Series Digital Transceiver and Receiver
Rules of Operation (1-way modes)
The following rules must be followed when setting up any Digi-Wave™ system. Failure to adhere to these rules will result in
unpredictable, unsupported operation.
• Up to 15 channels can be used simultaneously, i.e. one oor and 14 interpreters.
• There must be one Master 1 (usually this is also the oor), and only one, per group.
• Each Interpreter must be assigned their own channel number.
• Repeater function can only be used in 1-Way mode.
• When repeater function is used, all 15 channels can be utilized in one-way mode, i.e. one oor and 14 interpreters.
• When repeaters are used, Floor (channel 0) must be assigned as the master unit for the group. All other DLTs have to be
assigned as “GST”.
2. Decide Speaking Priority for each DLT.
There are 3 levels of priority. The M1 has rst priority, M2 has second priority and Guest units have third priority. The M1 or M2
will have to turn OFF their talk access to allow the Guest units to talk. When 2-6 people are talking in a group the participants can
hear their voices in the DLTs or DLRs.
The M1 and M2 have the ability to lock out other talkers by holding down the TALK button for three seconds. All system TALK
LEDs will continuously ash while other participants are locked out of the TALK feature. The Master 1 can override anyone else
talking within the group. Master 2 has talking priority over Guests.
Speaker priority is assigned as follows:
1st priority — Master 1 ( M1 ):
2nd priority — Master 2 ( M2 ):
3rd priority — Guest ( GST ):
3. Decide what Address(es) you will need.
Each DLT transceiver must have a unique address. Refer to the “Rules of Operation” (under Step 1) for the mode you are using, to
determine how you will address the units.
4. Decide what Group(s) you need.
Each set of people who want to talk and/or listen to each other must be in the same group. Up to 4 Groups can operate
simultaneously within range of each other.

Example 1: 2-way Mode, Tour Guide
HOW IT WORKS
1. Tour Guide 1 speaks, using a DLT alone (built-in mic) or using it with a compatible headset mic.
2. Each Tour Group Member and Tour Guide 2 listen directly to Tour Guide 1, each using a DLT alone (built-in speaker) or using it
with a compatible headset mic.
3. Tour Guide 2 then speaks, using a DLT alone (built-in mic) or using it with a compatible headset mic.
4. Each Tour Group Member and Tour Guide 1 listen directly to Tour Guide 2 using a DLT.
5. With the push of a button, a Tour Group Member uses a DLT (built-in mic) to ask the Tour Guides a question. Both Tour Guides
and all Tour Group Members listen to the question, each using a DLT.
6. Tour Guide 2 responds to the question, using a DLT. Tour Guide 1 and all Tour Group Members listen to the answer, each using
a DLT.
7. Tour Guide 1 responds to the same Tour Group Member question. Tour Guide 2 and Tour Group Members now listen to Tour
Guide 1’s answer, each using a DLT.
8. Tour Guides have two-way communication capability; they can talk/listen simultaneously to one another. Tour Group Members
can participate as listen-only or can ask questions with the quick push of a button. Tour Guides have the ability to take control
of the discussion by overriding Group Member (Guest) units, if needed.

How it Works: 6-way Intercom
Original (save)
Intercom Setup:
DigiWave 300 Series Digital Transceiver and Receiver
Example 3: Intercom (2, 3, 4, 5 or 6 simultaneous talkers)
HOW IT WORKS
1. There must be one primary “Master 1” unit per group (for synchronization).
2. Each secondary unit is set up as a “Guest”.
3. Up to six people can talk, and listen to each other, at the same time (6 Live mics).
4. In order to use this feature to it’s fullest, all units are programmed to be PnL, where the TALK button stays latched ON.
5. When a seventh talker wishes to speak, they push their TALK button, which knocks o the sixth talker. Six people are still
talking live, but now the seventh talker can speak, and the sixth talker just listens. This can continue for any number of talkers,
but only six can be talking (live) at the same time.
6. All units are operating in essentially a “2-way,” or “full-duplex” mode. However, the Intercom feature makes true 6-way
communication possible.
