1. 信道调节：
在正常开机并解锁状态下，短按"SET"键可进入手动信道调节的功能，默认从右通道MIC2开
始，屏幕对应的调节指示闪动，再次短按"SET"键可选择调节左通道MIC1,按"UP(▲)"、
"DOWN(▼)"键可以调到所需的频率和信道，3秒后自动保存并退出。
2. 手动对频（红外同步数码通讯）
A. 左通道对频：
正常开机并解锁状态下，先开启一个发射机并将发射机的红外接收窗对准接收机的红
外发射窗（0.5-3米范围内）。再长按"UP(▲)"键进入红外对频功能，默认从左通道MIC1开
始，左通道显示"〓〓〓〓〓"字符，选定2秒后自动进入对频状态，并从1格到5格递增且重
复，表示正在发送红外信息码（如下图所示）
右边的显示保持不变，接收机左通道MIC1显示"P〓〓〓〓"（如下图所示）说明对频成功并
自动保存退出。对频成功后发射机的频率与接收机的频率相同。如果5秒内对码不成功则自
动退出对码功能并保持原来状态。

B. 右通道对频：
先关闭左通道的已对好的那个发射机，再开启一个没对频的发射机，
接收窗对准接收机的红外发射窗长按"UP(▲)"键进入红外对频功能，默认从左通道MIC1开
始，2秒内再短按"SET"键可选择右通道MIC2，右通道显示"〓〓〓〓〓"字符。后
面的对频过程与左通道对频相同，频点之间间隔大于0.5MHz。
C. 另外其他通道的对频方法与以上方法相同。每个通道只能对一个发射机并且不能同频。根
据不同的环境，需要调到适应频点位置。调动参数后需要重新对频才可使用。
3. 自动对频 （自动搜索空闲信 道并对码）:
正常开机并解锁状态下，长按"DOWN(▼)"键进入自动搜索功能，默认从左通道MIC1开
始(2秒内再短按"SET"键可选择右通道MIC2)，屏幕显示频率数字变化且"字符闪动，表示
正在搜索中，从低到高搜索完整个频段的信道，然后显示并保存选定的空闲信道，同时自
动进入对码功能，5秒左右是否对码成功都自动退出；执行过程中短按"UP(▲)"键则退出此
功能。如果5秒内对码不成功则自动退出对码功能并保持原来显示的频点和ID码。为避免搜索
到相同频道，已对好频的发射机需保持开启状态及红外窗不要对准接收机。
4. 加、解锁功能：
正常开机并解锁状态下，长按"SET"键不放可以锁定接收机，此时屏幕显"LOCK"符
号，锁定状态时按键不起作用；接收机处于锁定状态时，长按"SET"键不放可以解锁，
此时屏幕显的"LOCK"符号消隐，按键功能恢复。加、解锁功能二边同步执行。

1. Signal Channel Adjustment
When turned on and unlocked, short press “SET” button to manually adjust signal
channel, which by default starts from the R-CH MIC2. You can also short press again to
switch to L-CH MIC1. During editing, the corresponding Adjustment Indicator will flash.
Adjust to a desired signal channel/frequency by pressing “UP(▲)” or “DOWN(▼)”,
then leave idle for 3s for the system to automatically save settings and exit.
2. Manual Sync (digital communication infrared sync)
A. L-CH Sync
When turned on and unlocked, turn on one transmitter, point the IR windows of both
transmitter and receiver towards each other (within 0.5~3m). Then press and hold
“UP(▲)” to enter IR Sync mode, which by default starts from the L-CH MIC1, indicated
by “〓〓〓〓〓” (5-bar meter) on the LCD screen. After 2s, the system automatically
starts syncing and transmitting IR code as the meter changes from 1 bar to 5 bars
cyclically, as shown below.

G108 8-Channel Wireless Conference System
12
When the frequency digits remain unchanged, and the L-CH MIC1 displays “P〓〓〓〓”
(shown below), it means that the frequency is matched successfully, setting is saved and
sync mode exited. Once synced, the transmitter's frequency becomes same as that of the
receiver. The system will automatically exit sync mode and return to its original status
after failing to sync in 5s.
B. R-CH Sync
First, turn off the transmitter synced with L-CH, and turn on another un-synced
transmitter. Position the IR window of the transmitter towards that of the receiver, then
press and hold “UP(▲)” to enter sync mode, which by default starts from the L-CH MIC1.
Within 2s, press “DOWN(▼)” once to select the R-CH MIC2, indicated by “〓〓〓〓〓”
in the R-CH LCD. The subsequent syncing steps are same as those for the left channel.
Spacing between frequencies used should be larger than 0.5MHz.
C. Follow the above steps for syncing in other channels. A transmitter can only be synced
to one channel at a frequency different from other transmitters. Find an appropriate
frequency depending on your environment. Frequency parameter changes on the receiver
will require re-syncing.
3. Auto Sync (auto search for free channel and sync)
When turned on and unlocked, press and hold “DOWN(▼)” to initiate Auto Sync
function, which by default starts from the L-CH MIC1 (or press “SET” again within 2s to
select R-CH MIC2). In Auto Sync mode, frequency digits on the screen will change and flash
during channel search, from low to high throughout the frequency band, then stop on a
free channel and be auto saved. Subsequently, auto sync function will engage, then exit
within around 5s regardless of successful sync or not. During Auto Sync, you can press
“UP(▲)” once to manually exit. The searched frequency and ID No. are kept in case of
auto exit after failing to sync in 5s. Keep synced transmitters turned on with their IR
windows pointing away from the receiver during this process to avoid finding an
already-used frequency.

4. Lock/Unlock
When turned on and unlocked, press and hold “SET” to lock/unlock the receiver,
indicated by the “LOCK” symbol on the LCD screen. When locked, other buttons
will not work.
Note: Transmitters at frequency band 640MHz-690MHz can only sync with the 4 channels
at the top of the receiver, while those at frequency band 612.25MHz-667.00MHz can only
sync with the 4 channels at the bottom.
When turned off, press and hold “UP(▲)” and turn on the receiver to enter system
menu settings. The screen will show “-SET-” before entering sub menu “-SQL-”; short
press “SET” to cycle through sub menus “-SQL-” L, “-SQL-” R, “RF OUT” L,
“RF OUT” R, “LIGHT” L, “LIGHT” R,“IDF UN” L, “IDF UN” R. The Adjustment
Indicator will flash next to the active sub menu; short press “UP(▲)” or “DOWN(▼)”
to select preferred setting for the sub menu.
1. “-SQL-”: receive restriction/sensitivity, 11 levels in total from -95 to -75. The lower the
number, stronger the receive capability but weaker the anti-interference. Adjust properly
according to the actual environment. -95 by factory default (strongest reception but
lowest anti-interference).
2. “RF OUT”: transmitter output power, either “H” (High) or “L” (Low), shown on
transmitter LCD when synced. “H” by factory default.
3. “LIGHT”: power-saving mode; “ON” keeps the transmitter LCD screen awake,
while “OFF” dims the screen (power-saving mode). “ON” by factory default.
4. “IDF UN”: “ON” or “OFF”; “ON” shows the ID Code (if any) on the Adjustment
Indicator on receiver LCD, while “OFF” does not. “ON” by factory default.
