Appendix
Adding and registering handsets/headsets
If registration fails, the system will automatically try to register again. If
registration fails after the third try, Registration failed appears on both
screens. The handset shows To register H�, see manual and the telephone
base returns to idle mode. This may take up to five minutes to occur. Please
start again from Step 1.
NOTES:
• You cannot register a handset if any other system handset is in use.
• If you try to register more than 12 handsets to the telephone base, the telephone base shows
Registration slots are full and sounds two beeps.
For registration, put the handset on the
telephone base, not the handset charger.
