TIPS:
According to the requirements of customers, KC level can be low level or high
level. Low level: when the power is on, KC SW is suspended, and when the short
switch is off, KC Di is low. Low level: when the mic is on, KC will be
suspended, and when the mic is off, KC will be adown. High level: when the mic
switch is on, KC wil1 be at the high level, and when the mic switch is turned
off, the KC will be at the low level. It is recommended that all customers use
low-level boards. If your OK board has a mute triode, just add one pull-down
resistor to KC. It will become to a high level.
NOTICE
- The receiving board should use a regulated power supply with a voltage range of DC5V 9.
- The receiving b0ard should be installed away from 1nterference sources. For example CPU MIC reverb IC/ Power switch/power source motor, etc.
- To improve the signal-to-noise ratio, please use low 1mpedance input: shielded wire for signal connecti line.
- For the best channel separation and convenient frequency compensation adjustment, please refer toUse the product arrow interface circuit diagram.
- The receiving antenna should be away from the ground, wall, and metal surface more than I meter, If it s too close, the system performance will be impaired.
- When using, please pull out the antenna (External) and select the appropriate angle Degree (generally vertical upward).
- When installing the built-in antenna, the antenna should be straightened and fixed Without bending or knotting:lt should be away from the frequency selection circuit and the RF output terminal. lt cannot form a circuit with it. Nor can it be connected with others.
- In order to achieve the best singing effect, Here, the distance from the microphone should be appropriate, There will be airflow impact if it is too close: to reduce airflow 1mpac t.
- If the microphone is not used for a long time, please take the battery out to prevent battery leakage damage.
- When the low battery indicator light is on, you should replace the battery in time.
- Do not throw or strike the microphone when using it, so as to avoid serious damage.
- Please do not use two same frequency to sing at the same time , 1t will cause howling8 or silence.
- Do not use gasoline, diluent, and other chemical liquids to clean this product, otherwise, the surface protective layer will be damaged: use soft cloth or neutral detergent to clean this product

Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
The device has been evaluated to meet the general RF exposure requirements. The device can be used in portable exposure conditions without restriction.
