USER COMMAND TABLES
The following user command table shows the user commands that can be carried out during a call. Successful commands are
signalled by two beeps from the telephone, errors are signalled by four beeps.
IMPORTANT NOTE: When the ED# function has been enabled the user must press the # button on their phone before pressing
any of the following user commands (also refer to ED# notes on page 38 for further information).

time has been set to latch simply press 6 on the phone to unlatch the output again.
Auxiliary input AO1 status indication is only possible when A1M mode has been set to mode 02 (also see notes on page 33, set
auxiliary output AO1 mode, and Fig.18, on page 19).
The next user command table shows the SMS text messages that can be sent to the GSM LITE intercom while in standby (the
examples shown in the table use the default 4 digit master code 1111).
