The radio will wait 10 seconds for a response. If the radio receives no response or something other
than a "Y" or an "N", the radio will use the configuration stored in EEPROM.
configuration is Zone mode.
reprogrammed.
If the new configuration is ECP mode, and the panel used is not capable of programming the radio,
the 7720P can be used during the power-up sequence (See ECP Mode Unique Programming section,
page 18). If the new configuration is zone mode, the 7720PLUS signon will appear immediately and
programming may begin. If the 7720PLUS has been programmed for the given configuration, the
LEDs will flash according to their functions. If the 7720PLUS has not been programmed, regardless
of configuration, the LEDs will flash in unison indefinitely.
Zone Mode Unique Programming
After connecting the 7720P cable, power up the 7720PLUS (plug in the battery connector and apply
power to the control panel). The following will be displayed:
4.xx = current software revision level
Programming is accomplished by answering displayed questions. Most questions require only a [Y]es
or [N]o response, while others require a numerical response (ID numbers, etc.). Press ENTER to
accept each response and proceed to the next question. A "?" indicates an invalid entry. The current
value is displayed on the second line in parenthesis (). To accept the current entry, simply press the
ENTER key. Use the UP/DOWN arrow keys to scroll through the programming questions without
changing any values.
Enter programming mode by pressing [ENTER] during the initial power up period (while LEDs are
flashing consecutively).
Pressing SHIFT-X will reset the 7720PLUS to its initial power up phase if it has already entered
program mode. The 7720PLUS reads its EEPROM to determine its pre-programmed parameters. A
CRC of the EEPROM locations is also read. If the computed CRC does not match the one read from
EEPROM or if the programming parameters are invalid, the 7720P LCD displays "NO PROG". While
the three LEDs flashes in unison, press ENTER to begin programming.

Password Protection
If desired, the programming options can be passweord protected.
NOTE: If using a terminal to program passwords, use only those characters available on the 7720P.
This allows later access using a 7720P Programming Tool (A, B, C, D, E, F, S, T, X).
Once a password is assigned, the following prompt appears upon entering programming mode:
See EXITING PROGRAM MODE paragraph later in this section for assigning and changing
passwords.
If the configuration has changed, the EEPROM MUST be
