When using, dispatch the Coaster Pager which with the Exclusive Code to the customers. The customer could find a seat to relax or go outside stroll about. When the Dishes are ready or have the empty seat, the staff would input the coaster pager No to notice the customer return. The Customer would notice this by Coaster pager ring, light or vibrate prompt. Extended Function: The system except work with the Coaster pager but compatible with the pager which with LCD display which wore by the manager or staff to fulfill the inner calling communication function. Special Function: We added the swipe the card function to fulfill the convenient queue function. In the coaster pager we could install the RFC, and Reader Module in the Transmitter. When Customer need queue Function, just swipe the Coaster Pager in the Transmitter, then it would be in queue state. When Calling the customer, just find that number in the queue and press the send key is ok. Which decrease the Waiters work greatly to improve the efficiency. 2 System Parameter 2.1 Transmitter Parameter Type Parameter Overall Size 220mm × 130mm ×45mm Display Resolution 400×240 Keypad T9（letter and numeric） 1 Power Supply 12V/ 3A Interface type USB、RS485（Ethernet available） Frequency Customization available Paging number in cache 40 Queuing display 3 digit LED nixie tube Card type RF Card Transmitting Power 0-2W adjustable Antenna External BNC Socket System Capacity Coaster Pager —999 Waiter Numbers——999 Default single key paging ——10 Timely paging ——10 Table 2.1 Transmitter Parameter 2.2 Coaster Pager Parameter Overall size 112mm(Diameter) × 17mm(Thickness) Frequency Customization available Sensitivity -110DBm Decoding POCSAG ，Support 7 group ID code 2 Coaster pager number 3 digit，001-999 Alert mode Vibration and sound，with LED flashes Out of Range Alert Alarm when out of the transmitter range Lower Power Prompt Buzzer sounds “didi” Water resistant design Surface water resistant Power supply 2.4V/600mAH Standby Current 500uA Temperature -0°C—+65°C Table 2.2 Coaster Pager Parameter 2.3 Charger Parameter Overall size 112mm(diameter) × 17mm(thickn…

FCC ID: WH2-T21 Report: S\SZ CONSTANT_WH2\1788UT14\1788UT14TestReport.docx Page 5 of 19 RF EXPOSURE INFORMATION: 47CFR 2.1093 This equipment is exempt from SAR. TEST PROCEDURE Power Line Conducted Interference: The procedure used was ANSI/TIA 603-C: 2004, using a 50uH LISN. Both lines were observed with the EUT transmitting. The bandwidth of the spectrum analyzer was 10 kHz with an appropriate sweep speed. Bandwidth 20 dB: The measurements were made with the spectrum analyzer's resolution bandwidth (RBW) = 1 MHz and the video bandwidth (VBW) = 3 MHz and the span set as shown on plot. Power Output: The RF power output was measured at the antenna feed point using a peak power meter. Antenna Conducted Emissions: The RBW = 100 kHz, VBW = 300 kHz and the span set to 10.0 MHz and the spectrum was scanned from 30 MHz to the 10 th harmonic of the fundamental. Above 1 GHz the resolution bandwidth was 1 MHz and the VBW = 3 MHz and the span to 50 MHz. Radiation Interference: The test procedure used was ANSI/TIA 603-C: 2004, using an Agilent spectrum receiver with pre-selector. The bandwidth (RBW) of the spectrum ANSI/TIA 603-C: 2004, receiver was 100 kHz up to 1 GHz and 1 MHz above 1 GHz with an appropriate sweep speed. The VBW above 1 GHz was 3 MHz. The analyzer was calibrated in dB above a microvolt at the output of the antenna. Table of Contents Applicant: SHENZHEN CONSTANT ELECTRONICS CO., LTD.
