OPERATION

SZ-VOXLINK-COMPACT – 2H/L

Power On/Off: To switch on the receiver or bodypack transmitter, press and hold the power button until you see the power indicator light (approx 2 seconds). To switch on the handheld mic, press and hold the power button until you see ‘On’ appear in the display (approx 2 seconds).

To switch off the receiver or bodypack transmitter, press and hold the power button until you see the power indicator go off (approximately 2 seconds). To switch off the handheld microphone, press and hold the power button until you see ‘OFF’ appear in the display (approximately 2 seconds).

Frequency Adjustment: The system has 3 pre-set frequencies for each channel, and you can switch between them by pressing the set button on the transmitter. The receiver will automatically pair with the transmitter without requiring further adjustments, provided that Intelligent Scanning mode is enabled (see below).

Intelligent Scanning & Fixed Frequency Mode:

When Intelligent Scanning Mode is enabled, the receiver will automatically detect the transmitter frequency and synchronise with it. When Fixed Frequency Mode is enabled, the receiver will not automatically synchronise with the transmitter if you switch transmitter frequencies.

To determine the current mode:

1. Switch on the receiver as described above, and watch the power indicator.
2. If the power indicator flashes 3 times just after the receiver has been switched on, this indicates that Fixed Frequency Mode is enabled. If it does not flash, Intelligent Scanning Mode is enabled.

To swap between Intelligent Scanning Mode and

Fixed Frequency Mode:

1. Switch on the receiver as described above.
2. Press the power button as if switching off the receiver, but keep the button pressed after the power indicator has gone off until you see the indicator flash 3 times. This will be about 8 seconds after the receiver has powered off.

Charging: The receiver and body-pack transmitter have built-in batteries. When the battery is low, the charging indicator will flash, indicating that it’s time to recharge.

SZ-VOXLINK-COMPACT – 4H/L

Power On/Off: To turn on or off the device, press and hold the power button for one second.

Transmitter A / B/C/ D Channel Switching: To switch between channels A, B, C, and D press and hold the set button for two seconds to perform a channel search.

Frequency Adjustment: The transmitter frequencies are fixed, so the receiver will automatically pair with them without requiring any manual frequency adjustments.

Volume Adjustment: For information on how to adjust the volume for the handheld microphone and lavalier function, please refer to the “Set Button” description.

Button Lock Mode Settings: This feature is only available for the handheld microphone. Please refer to the “Handheld Microphone Function” description to learn how to enable the button lock settings.

Charging: The receiver is powered by a built-in 2000mAh lithium battery. When the battery is low, the power blue indicator will flash at a frequency of 0.5 seconds, indicating that it’s time to charge. While charging, the red indicator will remain constantly on and turn off once charging is complete. Charging time typically takes around three to four hours.
