IMPORTANT NOTE: The ETP-CDMA-V Cellular Interface does not comply with Enhanced 911 
(E911) requirements mandated by the Federal Communications Commission (FCC). In order to 
comply with the E911 mandate, the ETP-CDMA-V Cellular Interface software prohibits the dialing of 
911. 
IMPORTANT NOTE: Programming of the ETP-400 Series Phones cannot be done through a 
remote call to the ETP-CDMA-V Cellular Interface.  For programming, an ETP-400 Series Phone 
must be connected directly to a standard analog phone line connection. 
IMPORTANT NOTE: The built-in auto-dialer of the ETP-400 Series Phone cannot dial a secondary 
number in round robin fashion when used in conjunction with the ETP-CDMA-V Cellular Interface. 
IMPORTANT NOTE: All programming, diagnostics, and identification of the ETP-400 Series 
Phones are accomplished through the transmitting and receiving of DTMF signals. Cellular 
transmissions and cellular networks may interfere with and distort these tones. As a result of these 
irregularities, model ETP-TAL Talk-A-Lert Polling may not function as intended and, therefore, may 
not be appropriate in that application or environment; ETP-TAL Talk-A-Lert Base Station will not 
function at all. 
In any event, due to these irregularities, programming of the ETP-400 Series Phone should be done 
on a land line (i.e., not through the ETP-CDMA-V Cellular Interface.
