Receiver Operation Instructions

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.
   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.

System Menu Settings

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.

Wireless Handheld Microphone Functions

1. Capsule Module (with built-in high-density foam): specially crafted for anti-rolling and impact-resistant properties.
2. LCD Screen: displays Channel, Frequency, and Battery Status.
3. IR Sync Window: for manual/auto frequency sync with receiver.
4. Power Switch: for power on/off, or switching operation status.
5. Upper Handle: for joining capsule and lower handle.
6. Lower Handle: can be opened by turning counterclockwise, encases a plastic holder inside.

Wireless Conference Microphone Functions

1. High/Low Output Power Slide the switch at the back of the transmitter to “L” or “H” to set to Low or High output power respectively.
2. Pickup Sensitivity Turn the Volume Level knob to “MIN” for lowest sound pickup sensitivity or “MAX” for highest sensitivity.
3. IR Sync
   Point the back of the transmitter towards the IR window on receiver to sync data.

Troubleshooting

If you cannot resolve the issue by the methods shown below, please contact the local dealer.

polarity markings for correct battery installation
Severely insufficient battery power.| Replace batteries
Smeared or rusted battery contact plates.| Clean or replace battery contacts
No response from receiver when powered on.| Mains outlet is not connected or live.| Check mains outlet
Receiver power adapter is broken.| Replace with an adapter of the same spec
Microphone is not turned on.| Turn on corresponding microphone
Frequencies do not match between Mic/Receiver.| Correctly sync frequency following the instructions in this manual
No reception on receiver.| Microphone is out of range.| Get back within effective range
Microphone is not synced.| Sync frequency before use
There is reception on receiver but no sound.| Volume knob is turned to minimum.| Check and properly adjust the volume knobs on receiver and amplifiers
Audio cable is not properly connected.| Check and connect the audio cable firmly in correct port.
Screeching sound.| Feedback howling.| Lower the volume, and keep the mic pointing
away from speakers; increase distance between mic and speakers.
Intermittent sound during use.| Out of effective range.| Get back within effective range.
Short effective operating range.| Environment is too complex.| Avoid overly complex surroundings, because large metals, brick walls or crowds in between mic and receiver will greatly reduce the effective range.
