INTRODUCTION
The operations described below allow you to rapidly and easily implement your VOKKERO Guardian communication sys-tem.
All the operations described are valid for all the VOKKERO® Guardian terminals listed below:
VOKKERO GUARDIAN - Show : VO8154AAD / VO8156AAD
Note: Your product reference is given on the label on the back of the terminal housing.
The VOKKERO Guardian system is ready-to-use; it features the following three main elements:
Terminals
Configurator/Charger: VOKKERO GUARDIAN - Configurator : VO8118AA
(Optional) Charger extension (1 to 4 maximum): VOKKERO GUARDIAN - Charger : VO8139AA
All the operating settings of the VOKKERO Guardian system are managed by the configurator which gives access to the Settings menu via a
touchscreen. The configurator must be connected to the power supply (otherwise it will not work) and up to 4 extensions units can be chained
with the configurator.
1. SYSTEM INSTALLATION PROCEDURE
Connect the power supply to the configurator or at the back of last chained charging unit if several are connected in a row.
Connect the power supply to the mains.
Insert the VOKKERO Guardian terminals in each slot as shown below.
Note 1: the position of each terminal in each particular charging slot has no influence on the nature of the configuration, except for Slot 1 (refer
to §3.2)
Note 2: if the purpose of the operation is solely to charge terminals or spare batteries, the use of extension unit only is fine.
The first configurator slot (i.e., closest to the LCD) is of importance to the system-configuration process; for more details, refer to §3.2.

3. STARTING UP THE TERMINAL
Before starting your terminal, make sure that it has been properly charged using a compatible
charger.
Note 1: all settings, including volume, are saved when switching temrinal OFF.
Note 2: When LCD screen is set in Sleep Mode, to switch the On Off button when terminal is On (with sleeping LCD) will wake
up the backlit LCD. To switch Off the unit, press On Off button a second time.
Press the On/Off button to turn on the terminal.
The LCD screen should turn on and display the VOKKERO® logo. The LED above the On/off
button should also light up permanently.
Next, the Welcome Screen displays, followed by the product user’s name. By default, user name
is”Guardian”. Name can be customized in the configurator for each terminal (refer to §4.3.1).
To turn off the terminal, press and hold the “on/off” button.

Microphone status
Either On or no microphone connec-
ted, or microphone Off.
3.1. LCD Screen Icons (by Default)
3.2. IMPORTANT: about M role
When setting up your Guardian Show system, the first step consists in attributing the Master role (M) to a single terminal of your
choice. This M role is crutial to synchronize the digital communication between every beltpack of the system.
The Master role (M) is automatically attributed to the terminal located in the configurator’s slot n°1 when doing a Quick Configura-
tion (See 4.2).
Note that Guardian Show system allows one M only in service, in order to perform normally. To attribute and operate more than one
M at a time will corrupt the entire system radio performance.
If you wish to use more terminals than your configurator’s slot capacity, or while terminals are already in operation, make sure to
always leave Slot n°1 free (empty) and use Fixed Key function (see 4.3.2)

To enter Menu, press and hold Channel trigger center switch.
To exit Menu, press and hold Channel trigger center switch or wait 5 seconds.
To browse Menu functions, lift Channel trigger up or down.

4.2. Functions descrition
4.2.1. Lock
Set Lock function ON to lock all terminal commands except for the headset Volume adjust and Menu access.
When Lock function is set ON, the menu is automatically exit.
To unlock the terminal, get back in the Menu by holding Channel trigger center switch, and adjust Lock to OFF position.
4.2.2. Gate Level
Adjust the mic gate between 3 gate levels: Soft, Mid et Hard (+ Off).
Soft gate beeing recommended for quiet environment or in the case Voice Detector is activated (see Voice Detector), Hard gate
beeing recommended for noisy applications.
Note that Gate Adjust is not available in Rigging Mode (see chapter 7)
Note that Gate cannot be set to OFF in Live Mode (see chapter 7)
Note that when adjusting Gate level, Side Tone is momentely activated (Post-Gate) providing a clear feedback when searching
for the most appropriate gate level.
4.2.3. Side Tone
Adjust the Side Tone between 3 different levels.
Side Tone can be heard only when Mic is activated (Latch or PTT)
At maximum Side Tone level, some external noises may be heard.
4.2.4. Voice Detector
The Voice Activity Detector (VAD) is a selective algorithm that allows to communicate in extremely noisy environment. By opening
the microphone path only when human voice is detected, the algorithm avoids loud noises to pass through coms. One big advan-
tage of the VAD is to keep hands free while trussing and stage rigging.
Note that the activation of VAD may generate extra latency.
Note that VAD is OFF by default except for Rigging Mode (always ON).
4.2.5. Voice Priority
One terminal of the system can be set from the Configurator Menu as the « Voice Priority » terminal. When Voice Priority is
on, any order from that particular beltpack will take over priority over the full duplex system, while incoming audio from other
beltpacks is decreased of -12dB.
Note that Voice Priority function is only vailable for one terminal of the conference.
Voice Priority settings does not appear on other terminals Menu (if not set from the configurator).
When Voice Priority is active, the display LCD screen shows a ‘+’ near by the Role Indicator mark.

Choose between Latch, PTT and Latch + PTT.
Each beltpack can be individually set as PTT, Latch, or PTT+Latch modes.
In PTT+Latch mode, a short push on the Mute button engages Latch (hands free – mic on) and another short push mutes the mic, while a
long push engages PTT and the release of the button mutes the mic.
Note that default setting is Latch for Rigging mode and PTT for Live and Studio modes.
Note that when using Live and Studio modes, to set more than two terminals with Latch may input too much ambiant noise into the sys-
tem.
