CRADLE SWITCH
Located in the handset cradle, this plastic lever is depressed by the handset (when placed in the cradle)
to cut off the line. Note: Depressing this cradle lever too briefly when intending to terminate a call may
result in an accidental “hookflash” that will inadvertently place the call on hold - this is known as “phantom
calls” because the held call may ring again at your extension within a few minutes (the other party will
have hung up, so it will seem as if you were called by a phantom, hence the name “phantom calls”). If
you experience this problem, when terminating your call please depress the cradle lever a little longer
before making/receiving your next call (i.e. phantom calls are not a system or telephone fault).
VOLUME and VOLUME KEYS
Used to adjust the hearing level of the handset earpiece, the handsfree speaker and the headset. To
adjust the volume, press the VOL+ ( ) and Vol- ( ) buttons located under the display (see Figure 2A).
Adjustment during a conversation will not be detected by the other party.
RECALL KEY
For use with a host system to invoke special system or network facilities such as call-hold or call
transfer which may be available in your network. It is sometimes referred to as the “Flash” key or
“Facility” key. To learn how to use it, please consult your telephone host system manual. Recall timing
is preset to 100ms. The Recall timing setting affects the Recall key’s ability to function correctly with
your system (see the Installation section regarding this setting).
REDIAL KEY
Press to redial the last number dialed, which may be up to 32 digits long. When pressed while still on-
line, the telephone will clear the call and retry the number. It can be used in Handset, Handsfree, and
Headset modes. Dialing more than 32 digits during one call will cause erasure of the entire number from
the Redial memory.
See further details of the 5-stack Last Number Redial memory in section 6 “Memory Operation”.
