IMPORTANT SAFETY INFORMATION NOTE : The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this equipment. Such modifications could void the user's authority to operate the equipment. Caution : Any changes or modifications (including the antenna) made to this device that are not expressly approved by the manufacturer may void the userโ€™s authority to operate the equipment. IMPORTANT NOTE: FCC RF Radiation Exposure Statement: This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 30 centimeters between the radiator and your body. This transmitter must not be co- located or operating in conjunction with any other antenna or transmitter. A. EASY INSTALLATION INSTRUCTION Step Lock the antenna to the right corner of the Boomerang waitercall Transmitter. (Fit over plug and twist left to lock antenna in place) Step Plug the Boomerang MBWC100Transmitter A/C adaptor into the Boomerang waitercall Transmitter and then into a standard outlet. A surge protector is recommended. B. OPERATION Write the server name next to his pager number with a dry erase marker. Warning!! Regular ink will make permanent marks, making name changes difficult-clean with a non- abrasive cleaner ONLY!! The name panels can easily be removed and replaced to simplify pager assignment. Press the number that corresponds to the servers name on the sending unit and that pager will silently vibrate. Range of this system should easily cover even the largest of restaurants. You can send a single, double or triple vibration to servers, sending them to different parts of the kitchen. For example, 1 vibe means going to the hot line, 2 vibes mean going to the salad station, etc. 1) To page a pager with a single vibe Press the corresponding pager number. If you set A-T(Alert type) function to vibe, then it will vibrate once. 2) To page a pager with a dual vibe (Button : 2X ) Press 2X MENU button once and then press the corresponding pager number within 5 seconds. You can label what 2X means on the space. The pager will vibrate 2 times. 3) To page a pager with a triple vibe (Button : 3X) Press 3X SELECT button once and then press the corresponding server pager number within 5 seconds. You can label what the 3X means on the space. The pager will vibrate 3 times. 4) To Sleep all pager (Button : 3X) Press 3X button more than 3 seconds and the green light comes on. All of pagers go to sleep. 5) To page all pagers Press ALL PAGE button more than 3 seconds and the green light comes on. All of pagers will receive the call. C. SYSTEM SETTING To enter programming mode, press the โ€œX2 and X3" for 3 seconds. The display will show โ€œHourโ€ Use the โ€œX2โ€ key to scroll through the several menu options, โ€œAll Pageโ€ key to select Manu and press โ€œX3โ€ key to cancel and exit the system setting menu. * X2: Menu All page: Enter X3: Cancel 1. hour With this feature, you can setup current time into the Boomerang waitercall transmitter.
