• AF GAIN (Audio Gain Adjustment)
• AF L-CUT (Low-Cut Filter)
• AF LIMIT (Audio Limiter)
• ENCRYPTION (Encryption Function)
1. Adjustable from 0 dB to 6 dB in 3 dB increments.
2. Increasing the AF GAIN narrows the dynamic range of the input
signal and increases the risk of system noise and feedback.
1. Options: L-CUT (Low Cut) or FLAT.
2. When set to L-CUT, the frequency response at 100 Hz
is reduced by approximately 3 dB.
1. Options: YES or NO.
2. When set to YES, the maximum output of the receiver is limited.
1. This is a display-only function; it cannot be set on the transmitter.
2. To enable encryption, configure it on the receiver in encryption
mode and synchronize using the SYNC function.
3. Refer to the receiver’s encryption settings for more details.
3. The specific group and channel set via PC software will be displayed
as “GRP - CH” with asterisks (**) replacing the numbers.

Cautions
1. Turn o the transmitter when not in use to conserve battery life.
Remove the battery if not used for an extended period.
2. Avoid covering the transmitting antenna (rear housing section)
with your hand to maintain transmission eciency.
3. Do not cover the microphone grille with your hand to prevent
degradation of sound quality, loss of directionality, or feedback issues.
4. Hold the transmitter properly to maintain an appropriate distance between the
microphone and the mouth, ensuring optimal sensitivity and sound quality.
5. Keep the microphone grille clean and unobstructed. After use, unscrew
and clean the grille to avoid debris aecting performance.
6. Follow the regulations of dierent countries regarding frequency
range, RF output power, and maximum deviation limits.
7. Refer to the actual product in the event of any specification discrepancies.
8. Do not spray alcohol directly onto the condenser capsule
to avoid damage and voiding the warranty.
