call.

- Press any DTMF key except for the designated hang-up key (9) to

reset the communication time to 5 minutes. When a DTMF key is

pressed, its designed shortcut function will also be executed along with

the communication time reset.

 If you wish to enable a designed shortcut function, please press the DTMF

key for at least 1 second.

 At 20 and 10 seconds before the communication time expires, CH-MG will

emit 1 beep via the telephone handset to alert the user.

 If the call recipient needs more talk time, he can press any key except for

(9) to reset the communication time to its preset duration.

 If no DTMF command is pressed during the speech period, the call will

automatically hang up and be recorded as an unsuccessful report. Each

phone number will be retried up to a maximum of 5 times accordingly.

6.4.3. Report Sequence

The Reporting Group determines the sequence of reporting.

One Report Index can only be assigned to one Group.

Reporting within a Group:

If there are multiple Report Indexes programmed within a Group:

 CH-MG will report according to the numeric order (e.g. 1 > 2 > 3, etc.) of

the Report Index in a Group. Report will stop when one report is

successful and CH-MG will regard reporting to this Group successful.

For example, if Report Index 1 and 4 are assigned to Group 1, CH-MG will

stop reporting if reporting to Index 1 is successful. If reporting to Index 1

failed, CH-MG will carry on reporting to Index 4.

 If all reporting in a group failed, CH-MG will retry reporting.

CH-MG will try reporting within the same group for up to three times, (or

until one of the reports is successful). If three times of trying within the

same group failed, CH-MG will regard reporting to this Group

unsuccessful.

From the example above, suppose all report failed, the report sequence

would be:

1 > 4 > 1 > 4 > 1 > 4

Reporting Cycle

 If multiple groups are assigned to the same event type (emergency or

status), CH-MG will report according the group numeric order from the first
