10. Security Code
The security code allows the user/installer to program the K-1900-6/7-IP phone with a PC and the required 'Viking IP
Programming" software. The factory set security code is 845464. If the security code of the phone is left as default, the
PC software will not require entering a security code to connect to the phone. It is recommended that the factory set
security code be changed.
Note: The security code must be 6 digits and cannot include a Q or a #.
11 . Access Code
The access code comes into play when a tenant calls the K-1900-6/7-IP and a visitor lifts the handset to answer the
call or the K-1900-6/7-IP automatically answers the call (see Inbound Call Mode). It is a 1 to 6 digit code (can not
contain " Q " or "#") that the tenant must dial before they are allowed to operate the door strike relays, as extra security
on inbound calls. Once a tenant has entered the correct access code, 2 beeps are heard and the user can now enter
any "Remote Access Operation Commands" (see page 15). The access code can be disabled if this basic security is
not required. This code is also used to enable transmit audio for silent monitoring.
