Notice
Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including
interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
OEM integrators and installers are instructed that the phrase. This device contains
transmitter FCC ID: WA2ST-100M must be placed on the outside of the host.
Warning: Exposure to Radio Frequency Radiation The radiated output
power of this device is far below the FCC radio frequency exposure
limits. Nevertheless, the device should be used in such a manner that
the potential for human contact during normal operation is minimized.
In order to avoid the possibility of exceeding the FCC radio
frequency exposure limits, human proximity to the antenna should
not be less than 20cm during normal operation. The gain of the
antenna for Cellular band must not exceed 1 dBi. The gain of the
antenna for PCS band must not exceed 1 dBi.

dial tone regardless of this setting, nor on the busy signal detection capability of the W and @ dial
modifiers. See Table.

7.10 AT+CNMI – New Message Indications to TE (Sec 3.4.1)
7.10.1 Description
Selects the procedure how the reception of new messages from the network is indicated to the TE when TE
is active (DTR signal is ON). IF TE is inactive (DTR signal OFF), message reception is carried out as
specified in GSM 03.38. This command enables the unsolicited result codes +CMT, +CMTI, +CBM, and
+CDS. (Please refer to 07.07 for more detail)

<mode>
0 disable unsolicited result code
1 Discard indication and reject new received message unsolicited result codes
when TA-TE link is reserved (e.g. in on-line data mode). Otherwise forward them directly to the TE.
<mt>
0 No SMS-DELIVER indications are routed to the TE.
1 If SMS-DELIVER is stored into ME/TA, indication of the memory location is routed to the TE using
unsolicited result code: +CMTI: <mem>,<index>
2 SMS-DELIVERs (except class 2 messages and messages in the message waiting indication group
(store message)) are routed directly to the TE using unsolicited result code:
+CMT: [<alpha>],<length><CR><LF><pdu> (PDU mode enabled); or
+CMT: <oa>, [<alpha>],<scts>[,<tooa>,<fo>,<pid>,<dcs>,<sca>,<tosca>, <length>] <CR><LF>
<data> (text mode enabled; about parameters in italics, refer command Show Text Mode

3 Class 3 SMS-DELIVERs are routed directly to TE using unsolicited result codes defined in <mt>=2.
Messages of other data coding schemes result in indication as defined in <mt>=1.
<bm>
ST-100M Module
43
0 No CBM indications are routed to the TE.
1 If CBM is stored into ME/TA, indication of the memory location is routed to the TE using unsolicited
result code: +CBMI: <mem>,<index>
2 New CBMs are routed directly to the TE using unsolicited result code:
+CBM: <length><CR><LF><pdu> (PDU mode enabled); or
+CBM: <sn>,<mid>,<dcs>,<page>,<pages><CR><LF><data> (text mode enabled)
If ME supports data coding groups which define special routing also for messages other than class
3 (e.g. (U)SIM specific messages), ME may choose not to route messages of such data coding
schemes into TE (indication of a stored CBM may be given as defined in <bm>=1).
3 Class 3 CBMs are routed directly to TE using unsolicited result codes defined in <bm>=2. If CBM
storage is supported, messages of other classes result in indication as defined in <bm>=1.
<ds>:
0 No SMS-STATUS-REPORTs are routed to the TE.
1 SMS-STATUS-REPORTs are routed to the TE using unsolicited result code:
+CDS: <length><CR><LF><pdu> (PDU mode enabled); or
+CDS: <fo>,<mr>,[<ra>],[<tora>],<scts>,<dt>,<st> (text mode enabled)
2 If SMS-STATUS-REPORT is stored into ME/TA, indication of the memory location is routed to the
TE using unsolicited result code:
+CDSI: <mem>,<index>
<bfr>:
1 TA buffer of unsolicited result codes defined within this command is cleared when <mode> 1...3 is
entered.
