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 Digiwave communication system consists of at least one DLT 100 2.0 and various combinations of DLT 100 2.0’s and DLR 60
2.0’s depending on the venue.
The DLT 100 2.0 is a 2-way transceiver, meaning that it can transmit and receive audio simultaneously. It can operate in one of 3
dierent modes:
1. In Two-way Mode, a speaker (with a DLT 100 2.0) can hear another speaker’s voice (from a second DLT 100 2.0)
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 100 2.0 units. In addition, DLR 60 2.0
receivers in the same group can also hear the broadcast.
2. In One-way Mode, one DLT 100 2.0 acts as a transmitter (speaker) and another DLT 100 2.0 acts as a receiver
(listener). In addition, DLR 60 2.0 receivers in the same group can also hear the broadcast. There are 4 one-way
modes.
3. In Signal Repeater Mode, the DLT 100 2.0 receives audio from another DLT 100 2.0 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 100 2.0’s acting as repeaters. Listeners can have either DLT 100 2.0’s or DLR 60 2.0’s to listen to the
broadcast.
The DLR 60 2.0 is a receiver only. Users of receivers can only hear what is being broadcast by DLT(s).
Combinations of one or more DLT 100 2.0’s and DLR 60 2.0’s in One-way mode, Two-way mode, or Repeater mode can be used
to facilitate dierent 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)
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.

Getting Started: Preprogrammed Systems
If a system has been purchased, you will not need to perform any programming. The system will have been congured to your
order. Turn chairman master on rst so other units can pair. Slave units will turn o after 5 minutes if they cannot nd a
master.
1. Charge all DLT 100 2.0’s. If using DLR 60’s, 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 DLR 60 2.0’s that will be used should have fresh
batteries.
2. Identify and turn on the Chairman Master (CM) rst, usually identied by a grey silicone cover. Turn on the DLT by holding the
power button until the LCD screen comes on. If Chairman Slave (CS) or Slaves are powered up rst they will turn o after a few
minutes if not paired with the CM. As Chairman Slave and Slaves are paired with the CM the CM and CS will show C-#. The #
refers to how many DLT 100 2.0’s are paired within the group, i.e. C-12 means that 12 DLT 100 2.0’s are paired with the CM or
CS within their group. This can be utilized as an attendance checker making sure everyone is connected with the group.
3. Once all the DLT’s are on, you can check the set-up status of all units by pressing the power/menu button momentarily to
scroll through the settings:
Chairman Master and Chairman Slave 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. (Note: F-7 rmware version does not have Time of Day).
All Slave units will display:
Address Number
Group Number
Secure Key Code (if entered)
Software Version
Time of Day (Not available on F-7 rmware version)
4. If headsets are to be worn, plug them into the jacks on the top of the DLT’s making sure that the Microphone and Earphone
plugs are inserted into the correct jacks.
5. The Chairman Master will usually be the rst speaker and should press the talk button momentarily to activate the microphone.
This will be conrmed 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 Chairman Slave and all Slave units should now be hearing audio from the CM 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 Slave unit to talk, either the CM or CS will have to turn their talk button o
by quickly pressing their talk button.

Before Programming the Digi-Wave™ System
Prior to programming the system, decide what mode you will need, and what priority each DLT will have.
Any two people can talk in a group at any given time. The CM will have rst priority, CS has second priority and Slave units have
third priority. The CM or CS will have to turn o their talk access to allow the Slave units to talk. When two people are talking in a
group the participants can hear both voices in the DLT’s or DLR’s.
The CM and CS 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.
1. Decide which mode you need.
A. 2-Way Mode
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 Intercomm, Portable Discussion and Personal Communication.
Rules of Operation (2-way mode)
The following rules must be followed. Failure to adhere to these rules will result in unpredictable, unsupported operation.
2-Way
There must be one, and only one Chairman Master (CM) per group.
If the CM unit is o, the Chairman Slave and Slave units will turn o after a few minutes.
Chairman Slave is optional and there can only be one per group.
Each DLT 100 2.0 must have its own address and the address cannot be duplicated within a group.
Maximum two Talkers 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.
Attendee count will only work with addresses 1-99 (Maximum 100 DLT 100 2.0’s with one Master at address 0).
With Secure Key Code active, all DLT 100 2.0’s within the group must have the same 4-digit code entered. (DLR 60s/DLR 50s will
not work with secured DLTs)
B. 1-WAY MODE(S)
In 1-way mode, DLTs listen to a speaker using a DLT, but they cannot communicate back to that speaker - instead they
communicate to DLRs. The most common applications are: Simultaneous Interpretation with one or more interpreters, or Tours
without audience participation (no Q&A).
There are (4) 1-way Modes:
1-way - Main Speaker
1-way - Interpreter
1-way - Repeater Mode
1-way - Receive or Listen Only (Not available on rmware version F-7)
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.

DLT 100 2.0 Digital Transceiver and DLR 60 2.0 Digital Receiver
7
There must be one Master (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 DLT’s have to be
assigned as “SLV”.
2. Decide Speaking Priority for each DLT.
There are 3 levels of priority (see below).
Any two people can talk in a group at any given time. The CM will have rst priority, CS has second priority and Slave units have
third priority. The CM or CS will have to turn o their talk access to allow the Slave units to talk. When two people are talking in a
group the participants can hear both voices in the DLT’s or DLR’s.
The CM and CS 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 Chairman Master can override anyone
else talking within the group. Chairman Slave has talking priority over Slaves.
Speaker priority is assigned as follows:
1st priority — Chairman Master ( CM )
2nd priority — Chairman Slave ( CS )
3rd priority — Slave ( SLV )
3. Decide what Address(es) you will need.
Each transceiver and receiver must have a unique address. Refer to the “Rules of Operation” to determine how you will address
the units.
4. Decide what Group(s) you need.
Refer to the “Rules of Operation” to gure out which groups you need for the mode you have chosen.

Programming the Digi-Wave™ System: DLT 100 2.0 Optional Settings
Secure Key Code:
When a group has been set up and the same Secure Code has been entered into all the DLT 100 2.0’s, the DLT 100 2.0’s
without this Secure Code entered cannot listen in on the group. This may be desirable in private or high security-level functions.
The same four digit code must be programmed into all of the DLT’s, Chairman Master, Chairman Slave and Slaves. If a dierent
secure code has been entered, participants cannot re-enter the group without re-entering the correct secure code. The only time
the Secure Code is displayed is when it is being entered. To block users from entering the set-up mode, refer to the SET-UP
LOCK (SLOC) feature (below).
1. Choose a 4 digit numerical code; i.e. 1357. You must use the same code on each DLT in the group.
