It adopts RF wireless technology with millions of different learning codes. The system includes 999-channel call buttons keypad and portable buzzer&vibration receivers. The call button keypad has 20 battery charging slots. Each receiver is rechargeable and labeled with a number. In standby status, it is plugged into the charging slot, while the client places an order, he(she) will be dispatched one receiver with a number, when the order is ready, press the keypad to call the number, the client will get it through the buzzer/vibration/LED indications. The queue system greatly improve the work efficiency and avoid the client waiting in a long queue. It is widely used in fast food restaurant, dessert shop, auto 4S shop or other queue occasions. ◆ 999 channels keypad call buttons ◆ 20 batteries charging slots ◆ Portable rechargeable vibration & buzzer receiver ◆ Independent storage memory avoiding data lost ◆ High receive sensitivity ◆ Self testing while power on ◆ Beautiful and fashionable designing Working voltage Charging voltage Receive sensitivity Battery capacity Decoder Dimmension Working frequency Standby current Working current Receiver DC3.7V (rechargeable battery) DC5V -107±2dBm 360mAh Learning code (AM) 49*101*11mm 433.92MHz 10±5mA 75±10mA (vibration) Diagram of call button keypad 2 Working voltage Working frequency Standby current Transmit current Encoder Dimmension Keypad call button DC 5V/6A (power adapter) 433.92MHz 24±5mA 100±30mA Learning code (AM) 150*300*33mm Antenna Charging slot Power in Receiver Keypad area Number paper 3 Diagram of receiver 【Power】 Press and hold the button for 3sec to power on the receiver, press again to power off.

Plug the receiver to the charging slot, it vibrates and sounds 5 times and then the blue charging LED on, the receiver enters charging status. 3. When client places an order, the service people give one receiver to him(her) and note down the number. 4. While the order is ready, the service people press keypad to call the client (number), the corresponding receiver gets the information and prompts vibration/buzzer/light for 5min. After that only the 3 LED indicators flicker. Press the “Power/Reset” button or plug back to charging slot to reset charging/standby status. 5. The client gives back the receiver to service people, the service people put the receiver to charging slot and provide service. 6. While the receiver is in charging, press the number on keypad, the corresponding receiver LED indicators will flicker 3 times to report its position.

In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been defined as mobile device whereby a distance of 0.2m normally can be maintained between the user and the device, and below RF Permissible Exposure limit shall comply with. In accordance with KDB447498D01 for Simultaneous transmission MPE test exclusion applies when the sum of the MPE ratios for all simultaneous transmitting antennas incorporated in a host device, based on the calculated/estimated, numerically modelled or measured field strengths or power density, is ≤ 1.0. The MPE ratio of each antenna is determined at the minimum test separation distance required by the operating configurations and exposure conditions of the host device, according to the ratio of field strengths or power density to MPE limit, at the test frequency. Either the maximum peak or spatially averaged results from measurements or numerical simulations may be used to determine the MPE ratios. Spatial averaging does not apply when MPE is estimated using simple calculations based on far-field plane-wave equivalent conditions. The antenna installation and operating requirements for the host device must meet the minimum test separation distances required by all antennas, in both standalone and simultaneous transmission operations, to satisfy compliance. 3.
