3. How to use3.1 Relay PartThe Multicom Repeater is consist of two parts, Relay part for repeating between repeaters - Left side LCD and Local Communication part for communicating between Repeater and its belonging up to 4 Multicom handsets - Right side LCD.1) Power On/OPress the "Power S.W" switch to the upward to turn the stationary power on. The LCD display is on and shows the default volume level with "VOL 03". If you pressed the "Power S.W" to the downward, the stationary power is turned o.2) Group selectionPress and hold the "Mode" button longer than 3 seconds after turn the device power on. The "GRP" symbol on the LCD is blinking. Select the Group number 0~2 as you desire by press "̵" or "̷" button and then release all the buttons longer than 5 seconds to x it.Note; It is required to have the same group number between the repeaters you want to relay the communication consecutively in a relay system and also keep a distance longer than 10m between repeaters.Show the selected Group Number "00" Show the selected Group Number "01"Left side LCD- Relay partRight side LCD - Local Communication partLeft side LCD
Show the selected Group Number "00" Show the selected Group Number "01"3) Group selectionPress and hold the "Mode" button longer than 3 seconds after turn the device power on. The "GRP" symbol on the LCD is blinking. Select the Group number 0~39 as you desire by press "̵" or "̷" button and then release all the buttons longer than 5 seconds to x it.Every radio needs to have a same Group number to communicate each other in a group.3.2 Local Communication part1) Power On/OPress the "Power S.W" switch to the upward to turn the stationary power on. The LCD display is on and shows the default volume level with "VOL 03". If you pressed the "Power S.W" to the downward, the stationary power is turned o.2) Volume Up / DownIt gives you to adjust the hearing volume level with 9 steps as per you prefer.Press "̵" button to control volume up and "̷" button for volume down after turn the device power on. It is available to adjust the volume level 0~9 from low to high.Note; The default volume level is 3 and the volume level returns to 3 all the times whenever you power switch turned o and on.
4) ID selectionIn a group, every Multicom devices needs to have each dierent ID per devicefrom "00" to "99".The ID "00" becomes a master device in a group and every group needs to have a master device with ID "00" per group without alternative. The "MASTER" is displaying on the LCD as soon as the ID "00" is set.Press and hold the "Mode" button longer than 3 seconds after turn the device power on. The "GRP" symbol on the LCD is blinking. And press the "Mode" button one more time instantly. The "ID" symbol on the LCD is blinking. Select the ID number to “00” per Repeater by press "̵" or "̷" button so thatevery Repeater becomes a master station in a group and release all the buttonslonger than 5 seconds to x it.And Multicom handsets who belong to the Repeater station need to tune the same group number as the Repeater has and set every dierent ID from "01" to "99" per Multicom handset in a local communication group.5) Audio Output mode High / LowIt serves you to choose higher audio output or lower beside of Volume Up / Down. The higher audio output is eective when you listen to the device at the heavy noise place. Press and hold the "Mode" button longer than 3 seconds after turn the device power on.The "GRP" is blinking on the LCD. Press the "Mode" button 6 times instantly.Select either "UH" for higher audio output or "UL" for lower audio output by press "̵" or "̷" button and then release all the buttons longer than 5 seconds to x it.
6) Microphone sensitivity level controlIt is available to select the microphone sensitivity up to 5 steps according to the environment you have. Press and hold the "Mode" button longer than 3 seconds after turn the device power on.The "GRP" is blinking on the LCD. Press the "Mode" button 5 times instantly.Select the microphone sensitivity level 1 ~ 5 as per you desire by press "̵" or "̷" button and then release all the buttons longer than 5 seconds to x it.Note; 5.1) Its default setting is "UL". 5.2) There might be a kind of white noise creation when you set the audio output at "UH". Hence, it is recommendable to set the audio output at "UL" except using the device at the heavy noise surround place. Note; 6.1) The "C 1" is the lowest microphone sensitivity level and "C 5" is the highest. 6.2) Its default setting is "C 1".7) Portable usingIt is available to use the Repeater as a portable device rather than the xed station.Please connect the Power bank for Mobile phone into the USB port of Repeater.After that, place the Repeater wherever you preferNormal Audio Output mode Loud Audio Output mode

5. How to install5.1 Single block repeating with two repeaters700~1,000 m700~1,000 m* The group number in a relay part between Repeater 1 & Repeater 2 needs to be the same.* The group number in a local communication part between Repeater 1 & Repeater 2 needs to be dierent.* The group number between Repeater 1 and its belonging 4 Multicom handsets need to be the same.* The group number between Repeater 2 and its belonging 4 Multicom handsets need to be the same.* The ID number of Repeater 1 and Repeater 2 need to be "00".* The ID number of each repeater's belonging 4 Multicom handsets per group need to be dierent.<Expanded communication coverage around 2.1km~3.0km total>Repaeter 1700~1,000 m Repaeter 2Relay partID : 00Local partID : 01Group : 00 Group : 09Relay partID : 01Local partID : 01Group : 00 Group : 19
Notice ; It is required to keep a distance longer than 10m at least between Stationary and Stationary. Otherwise, it might cause the interference each other and thedrop of performance on both stationeries. 5.2 How to set between Repeater 1 and Repeater 25.3 Line repeat communication between Repeater and Repeater(To be conrmed)1) Relay partTune the group number “00” on Repeater 1 and Repeater 2.Even it is available to use any other Group number, It is required to tune thesame group number between Repeater 1 and Repeater 2.Set the ID “00” on the Repeater 1 and set the ID “01” or any other numberexcept “00” on the Repeater 2.2) Local partSet the Group number “09” on Repeater 1 and its ID number “00”.Set the Group number “19” on Repeater 2 and its ID number “00”.Even it is able to use other Group number on Repeater 1 & 2,It is recommendable to set the Group number far from “00” and also dierenteach other between Repeater 1 & 2 as many as possible to minimize themutual interference.It is available to repeat the communication in one Repeater to the other Repeater by cable connection between two Repeater.Please connect to two XLR 3 port of Repeater by using “XLR Repeateronly cable”. In this case, each Repeater are able to do full duplex communicationwith 9 Multicom handsets per Repeater, Which means total 18 peoplein full duplex.
