RTU-292C PASSWORD PROTECTION
The password protection feature is enabled by a dipswitch setting (SW1-5, see Table 2-11 Table
2-1. When passwords are enabled, access to the system is denied unless a user enters the correct
password. The same password applies both to access via telephone and via a radio (if the DTMF
Radio Access feature is used). Users are given three tries to correctly enter the system password
before the RTU-292C terminates the call attempt and returns to its waiting state.
The system assists the user in entering the password using Voice and Tone Prompts (if the Voice
Prompt Option is installed), or simply with Tone Prompts.
The factory default password is “
1 2 3 4
”, and this password can be changed to any DTMF or
numerical value up to 10 characters in length. To change the password, first enter the
programming mode by entering ‘
* 9 9
”. If passwords are currently enabled, it will be necessary
to enter the correct password to continue programming. From the programming mode, enter “
*
1 x x x #
” where “x x x” is the new password, up to 10 characters long. Next enter “* #” to leave
the programming mode.
3.7.8
INACTIVITY DISCONNECT TIMER
The inactivity disconnect timer ensures that the system does not remain locked up on a completed
call if system users forget to or are unable to terminate a call by normal means. The inactivity
timer samples audio from both the radio and the telephone. If no activity is detected for a time
equal to the Inactivity Disconnect Timer setting, the RTU-292C will notify the users by three
short beeps that they have five seconds to respond or the call will be terminated. If either the
radio user or the PSTN caller initiates activity within 5 seconds of the warning beeps, the timer
is reset.
Inactivity Disconnect Timer lengths of 2 minutes to 120 minutes (or disabled) are available.
Enter “
* 9 9
” to enter the programming mode, then “
* 2 x
” to set the timer. The value of x sets
the timer length. See Table 3-2 for the list of timer durations. The value of x = 0 will disable the
timer so that the connection may be maintained indefinitely. Unless a permanent connection is
required, disabling the timer is not recommended. If the telephone caller does not correctly
terminate the call, the unit can become locked up in the connected state. Once the desired timer
length is set, enter “
* #
” to leave the programming mode.
3.7.9
CALLING TIMER
The Calling Timer determines how long the RTU-292C will attempt to place a telephone call.
Once the timer expires, the RTU-292C terminates the attempt. Note that if the unit detects a busy
signal or other feedback that indicates that the call cannot be placed, the attempt will be
immediately terminated.
