If the memory contents are lost or corrupted, they can be restored to
original default settings by reinitializing them. (See the section below

Input character arrays of commands quickly and sequentially.
Too slow input (taking more than 5 seconds in the initial setting)
results in
command error

4.4.2 Memory Register Initialization
The
memory registers
can be restored to the
factory default
values at any time by using
one of the following two methods.
1) Memory Register Initialization by hardware:
Use either methods stated below, in which the modem attempts to read Pin 13
(/DefParam
) of the
serial communication connector
at the startup and starts initializing
the
memory registers
when it is “L”.
Method 1. Set “L” level to Pin 13
(/INIT
) of the
serial communication connector
with the power turned off. When the power is re-supplied, the
memory registers
are initialized and the modem starts operation in the
factory default
state.
Method 2. Set “L” level to Pin 13
(/INIT
) of the
serial communication connector
while the power turned on. In this state, force “L” to Pin 11
(POWER ON
) of the
serial communication connector
more than 1ms, then return the level to “H”. The
modem once becomes the
Shutdown mode
and returns to
Active mode
. Since this
sequence is the same as the
reset
, the
memory registers
are initialized and the
modem starts operation in the
factory default
state.
2) Memory Register Initialization by Command:
1. With the modem power is on and the communication software running, enter “
@
INI
CR/LF
”
at the terminal prompt.
2. The modem responds with “P0”
response
and immediately begins to operate using
the initialized
factory default
state.
While initializing the
memory registers
, do not turn the modem’s
power off. It take about 1 sec. to initialize the
memory registers
.
