A50 HANDSET REGISTRATION
1     Begin with handsets fully charged for 24 hours.  Remove 
all handsets from the charging bases, bringing all of them to the 
main base and setting them on the counter right next to the 
main charging base. (The handsets cannot be registered while 
they are in the charging base). Get ready for this 2-handed 
process. 
2     Put your one finger on the PAGE button on the main 
base.   Very important - - You must hold this button down 
during the whole registration process for all involved handsets 
without lifting it off. If the button is released, you must start 
over. 
3     At the same time - - with your other hand, press and hold 
the "CH" button on the 1st handset until you hear 2 quick 
confirmation beeps. 
4    Immediately move your hand to the next handset – without 
lifting the PAGE button, press and hold
 the "CH" button on the 
2nd handset until you hear 2 quick confirmation beeps.  
(Repeat for 3
rd
 handset if applicable – without lifting the PAGE 
button). 
5   Release your hand from the PAGE button now on the main 
charging base. 
6  Handset  1  should  now  show  "HS-1"  on  the  display. 
Handset 2 should now show "HS-2" on the display. (If you have 
a 3
rd
 Handset, it will now show “HS-3”). 
7  You should now have a dial tone on all the handsets. 
NOTE: 
If any handset loses registration, then this process must be 
repeated for all handsets in order to bring all handsets back into 
registration.
