1) One calling bell at each bed head. (GDT07W) 2) One calling bell at each bathroom and toilet (GDT08W) 4) One set of Display Unit in the corridor. (GDH500) 5) One Main Units for pager (GDH300) 6) One pager for each nurse (GDM200) 7) Software for attendance management Total amount will depend on the size of your hospital and the number of nurse, beds, doctor. How it works: When client need service, he or she just press the table button (GDT05), the signal will be transmitted to the waiter's watch receiver though relay station (GDH300). Then, the waiter will receive the table number with a vibration or ¡°DIDI¡± sound on the watch receiver (GDM200). The table number will also be shown on the LCD display machine (GDH100 or GDH500) at same time. The relationship between table number and water receiver will be programmed previously. And if the lead manager would like to appoint some one to service a certain table, he or she could dispatch the waiter by a dispatch machine (GDT20).
