AT&T 2820 - Manual (Page 30)

EN • Once the handset is located, touch any key to discontinue paging.
The ID-2820 may be used with any industry standard two-band
2.5mm headset (not included). Connect the headset to the jack
located on the side of the handset. Your phone is now ready for
headset use. You can purchase a suitable headset from AT&T or from
any electronics retailer that sells phone equipment.
The ID-2820 provides multiple handset capability supporting up to 4
handsets. Each accessory handset (model AT&T ID-282H) comes with
a charging cradle you can plug into any electrical outlet. No extra phone
jack is required. Many extra functions become possible when there is
more than one handset in your system. Call the AT&T Customer Service
Center to find out how to purchase accessory handsets (AT&T ID-282H)
at 800-667-2118.
The handset and base unit are factory pre-registered with each other.
Therefore, the unit should be in full working order when it is received. When
you purchase an accessory handset (model ID-282H), it will be necessary
to register it to the base unit in order to make and receive calls.
You can register up to 3 more handsets to make and receive calls via the
same base unit. Handsets are numbered 1 to 4.
If your handset is not registered to the base “NOT REGISTERED” will
display on the handset. The handset must first be registered to the base
to be used.
To register a new handset:
1. Touch and select the Security Set menu >Registration.
2. Use or to select the base
number for registration.
3. Touch to confirm.
