Use the USB-C located on the bottom of DLT transceiver or the DLR 400 RCH Receiver, to charge the battery. Charge by either using a USB-C cable or using an approved, compatible Williams AV charging station. Full charging time is approximately 5 hours. The charging LED flashes red while charging. The charging LED will turn to a steady green light when the battery is charged.

Digi-Wave 400 Series Hearing Assistance Hearing Assistance mode is appropriate when using the device to amplify spoken communication between users. The Tone Control in Hearing Assistance mode is automatically elevated, allowing the user to hear more clearly. Users with transceivers can be allowed to speak, which may be useful in a classroom setting.
• Each DLT transceiver must have its own address and the address cannot be duplicated within a group. • Each group must be assigned its own group number. Williams AV recommends a maximum of four groups using the system simultaneously within the same area to prevent interference.
Digi-Wave 400 Series To change any of these settings, hold down the menu button. For instructions on configuring the Digi-Wave system, see “Basic Settings” on page 11. Signal Strength Indicator When a Master 1 is available on the group or channel, the signal strength indicator on DLR Receivers and Guests will indicate how strong the signal is.
Digi-Wave 400 Series the Master 1 device, once a connection is established. If a group or channel is locked by a PIN, the device will prompt for the PIN at this time. The device will be unable to join the group or channel without this PIN.
Digi-Wave 400 Series Advanced Settings Advanced Settings are usually available regardless of the mode selected, but some Advanced Settings may be missing from certain modes, or with certain configurations. Number of Microphones (DLT 400 only) In modes where multiple speakers are available, the number of speakers at one time can be limited. The maximum number of speakers is 6, the minimum is 2 when this option is available.

Digi-Wave 400 Series In-First-Out order continues each time a member pushes their Talk button who is not a part of the speaking group. Talk Mode: Push-to-Talk and Push-n-Latch (DLT Master 2 and Guest Only) On a DLT transceiver, the Master 2 or Guest Talk Mode can be changed to Push and Latch or Push to Talk.

Digi-Wave 400 Series Sleep Mode “No sleep mode” is default. This setting means that the DLT 400 or DLR 400 RCH display will always stay on. There are three options for sleep – after 30 seconds, 1 minute or 5 minutes. If one of those options are chosen, then the display or the DLT 400 or DLR 400 RCH unit will turn blank after the prescribed time.
Digi-Wave 400 Series 1. Go through the menu system until you are prompted if you would like to use a PIN code. 2. Select “NO PIN CODE.” The existing PIN will be removed. Allow Join Group The Master 1 can prevent other devices from seeing the group as available to join. Disabling Join Group will prevent available groups from being listed under the Join Group menu.
Digi-Wave 400 Series Repeater Broadcast Mode Repeater mode can be entered by selecting it as the Broadcast Type during setup. An additional DLT 400 can be set-up as a repeater to increase the range of each channel. When repeater mode is used, the Repeater is configured as the Master 1, and all units sync to this Master Repeater.
Page 17
Digi-Wave 400 Series This mode eliminates the need for the interpreter to physically switch between 2 DLT transceivers programmed to fixed channels. The interpreter can easily switch between which channel is being broadcast by using the up or down arrow under each channel listed.
Digi-Wave 400 Series Relay Mode Relay Mode allows the interpreter to quickly switch Presenter between listening to the Floor on Channel 0 or the (Floor) Relay on Channel 1. Ch 0 Japanese For example, the floor is speaking Japanese. The...
Court Mode is only available for DLT 400 transceivers and DLR 400 RCH receivers. It is not available for DLR 400 ALK units or for backwards compatibility with the Digi-Wave 300 Series. For older Digi-Wave 400 series units, a firmware update may be required to use Court Mode. Group Selection A Master unit can only be in one group and cannot toggle between groups.
Digi-Wave 400 Series Saving and Replacing Profiles After settings have been configured, you will have the option to save your settings as a profile, or replace an existing profile. This is only available if Advanced Settings have been adjusted. If you choose to not save your profile, the device will still use the settings but they cannot be loaded again if the settings are later changed.
To check if your DLT is the AIM variant, check if the word “AIM” is present under the battery symbol on the display. Contact your local Williams AV representative regarding possible upgrade paths to the DLT 400- AIM variant.

Digi-Wave 400 Series separate spaces. You can also utilize sub-groups to limit the number of channels visible on the receivers. For example, if only channels 01-16 are active in 24-channel mode, then you could set up a subgroup for channels 01-16 and program the DLRs to be in that subgroup for the receivers to avoid seeing non-active channels.

Digi-Wave 400 Series Advanced Comms Mode Advanced Comms mode facilitates efficient and flexible communication between a Leader and several teams. In the Advanced Comms mode, a Leader (LEAD 1 communication role and optionally, the LEAD 2 role) can quickly and seamlessly switch between up to 4 teams (sub-groups). The sub-groups can be named using a standard list of commonly used team functions or with a custom name of up to six characters.

Digi-Wave 400 Series Sync Role: MAIN SYNC Exactly 1 DLT 400-ACM must be designated as MAIN SYNC. The system synchronizes to this unit, so it determines the coverage range. Most aspects of the system set-up are programmed on the MAIN SYNC unit (or an optional CONTROL unit) with other units in the system acting according to permissions set-up in the MAIN SYNC.

Digi-Wave 400 Series Subgroup Naming The subgroup name can be chosen from a list of common teams, or you can create a custom 6-character name (letters, numbers, blank). Subgroup naming is done on the DLT programmed as MAIN SYNC (or an optional Control unit).
Page 55
Digi-Wave 400 Series 3. At the end of the custom naming process, the created name will be shown (in this example “TEAM 1”) and there is a choice to accept this or not. If YES is pushed, then you will be taken to the next step in the process.

Digi-Wave 400 Series D. Programming Optional DLR 400 RCH Units The following steps are for DLRs to be used as listen only units for those who do not need to communicate with the group. Only DLR 400 RCH (not DLR 400 ALK) units can be used in Advanced Comms mode.
Page 57
Digi-Wave 400 Series Programming of Scenario 2: MAIN SYNC is mounted in a Fixed location In many situations, having the MAIN SYNC in a fixed location provides the best coverage possible for your system. We recommend using a Digi-Wave Connect DWD 401 with the fixed DLT 400-ACM to supply it with constant power and to provide flexible mounting options.
