QBTLTK-25Pager Transmitter

1 Waitercall 25 transmitter User’s manual Thank you for purchasing LEETEK’s Waitercall 25 paging system. Your system has been Pre-programmed at the factory and will function once mounted and plugged in. SYSTEM PROGRAMMING MENU *All programming should be done from the main terminal if an additional / cancel panel is used. 1. To enter programming mode plug in the Unit while holding the 3X button 2. You will see the numbers 1 – 12 either flashing, solid Red or Solid Green 3. The menu is as follows: #1 = Set the Current Time (hours, minutes & am or pm) #2 = Set the Sleep Shutdown Time (hourly 1-12, am or pm) * *Be sure the times are set correctly or your pagers could go to sleep in the middle of a shift! #3 = Sleep Shutdown Green = Active, Red = Inactive #4 = Page the Manager Green = Page Manager on Blinking Red, Red – No Manager page #5 = Page on Transition Green = Page Waiter on First Button press and all color transitions Red = Waiter paged only on the first press #6 = Set transition timers - how long between green to yellow to red transition #7 = Not used #8 = Not used #9 = Not used #10=Not used #11=Not used #12=Simple Page Green = Page waiter on first button press only. 4. To save the configuration at any time, hit the x3 button while at the top-level menu. Programming & Configuration Instructions To enter the programming mode, plug in the Unit while holding the X3 button. You will see the numbers 1 – 12 either flashing, solid Red or Solid Green. After setting the configuration below, press X3 button to save all the settings. 1. Set the Current Time Menu The numbers 1-12 can be pressed to correspond to the hours of the day. After pressing #1, press 1-12 to adjust the hour. To set the minutes, press either the #13 button (to scroll up) or #14 (to scroll down). Use the flashing all sleep button to toggle between am & pm. The dot on the top middle portion of the LCD indicates PM. (If the dot is there it’s pm; if there is no dot it is am) Note that this current time must be set in order to have an accurate sleep shutdown. Press the x3 button to exit this menu. 2. Set the Sleep Shutdown Time Menu The numbers 1-12 can be pressed to correspond to the hours of the day. After pressing #2, press 1-12 for the hour you want the pagers to turn off for the night and use the flashing all sleep button to toggle between am & pm. The dot on the top middle portion of the LCD indicates PM. (If the dot is there it’s pm; if there is no dot it is am) Press the x3 button to exit the menu and set the time. Note that when the internal clock reaches this time, all the pagers will be put to sleep. 2 3. Sleep Shutdown Active or not If you want the pagers to automatically go to sleep at a specific time (by “B” above) this light should be green. If the light is red the shutdown signal will not be sent. 4. Page manager on Blinking Red. If this light is green the managers’ pager will be paged when any button pressed goes to blinking red. You must have a numeric manager pager if you want the servers number sent with the page. 5. Page on transitions If this light is green the server will be paged upon each transition. (i.e. – when each button pressed turns yellow, red & flashing red the waiter will be paged.) All pages must be cancelled (by pressing the button again) when the food is picked up. 6. Set “Page Transition Timers” Menu This controls how long it takes for the transition from green to yellow to red to flashing red takes. 1 is the shortest period of time and 6 is the longest. Default from the factory is #5 (60 seconds) 1=10 seconds, 2=20 seconds, 3=30 seconds, 4=45 seconds, 5=60 seconds, 6=90 seconds 7-11. NOT USED AT THIS TIME 12. Simple Page When the light is green the system will page waiter on first button press only. The light will stay green for 5 seconds and then turn off with no further action. NOTE: The light on button # 5 should be red, to make this function work. Questions, Comments, Concerns? Call NTN at 82-32-678-8605 Help! I Need Service! Help is only a phone call away!
