Shift and Hist Keys
The bottom left and right keys on the large screen telephones are called the Shift and Hist keys.
The Shift key toggles the LCD screen between flexible keys 1~10 and flexible keys 11~20. The
Hist key accesses the Caller ID history. These buttons have no function when the telephone is
connected to a Strata CIX system running on software released prior to R5.2 MT021.
Speaker Off-hook Call Announce (DOCA-1A)
Digital telephones equipped with DOCA-1A can receive Speaker OCA which enables stations to
receive internal calls over their speaker while on another call using the handset. The DOCA-1A is
not required in a telephone to originate OCA calls or in a digital telephone that receives OCA calls
through the handset or headset.
Speaker OCA Interface (DOCA-1A) cannot be installed in DP5008D telephones.
