PROGRAMMING
Table 2 lists all of the features that may
be altered using the programming strings
shown. The factory defaults are also
shown and typically work for 99% of the
installations used by our customers.
Also, if errors are made in programming,
sometimes the G-9420 will respond er-
ratically. To reload the factory defaults,
remove the G-9420 cover and install
jumper J3, located next to the square
shaped processor. Turn the power switch
off and then back on (cycle the power),
and remove the jumper. The defaults have
now been reloaded.
To program a string from Table 2, con-
nect the G-9420 to either a telephone line
or a telephone line simulator. Call the unit
and when the first double-beep is heard,
key in the command string ensuring that
the * is the first character entered. When
the command string is entered, the G-
9420 will respond with a double-beep to
indicate that it recognizes the string and
has stored the new parameter. The pro-
grammer may load one or multiple com-
mand strings during the same steering
window.

COMMAND STRING CODE
DESCRIPTIONS
(DTMF Tones are initiated by the LINE
IN telephone key pad)
" * "
Enables or starts the ability to pro-
gram a command string into processor
at the time of the steering window.
" # " The "#" sign (DTMF Tone Code)
during the steering window will com-
mand the G-9420 to hang up or go back
ON HOOK. Exception to this is after en-
tering a command string the first "#" tone
"sets" command into the processor and if
followed by a second "#" tone, will place
the G-9420 back ON HOOK.
