The handset is unable to set the household number
When the handset is connected with an Apartment
interface, the household number cannot be set . When
the last two digits of the household number are
higher than the number of users (#II) on each floor, the
household number cannot be set . For example, if the
handset is programmed for one-riser two-households
on each floor, then it will be illegal to set the household
number as 203 .
15 .
Some parameters cannot be set.
Some parameter settings in the handset rely on other
parameter settings, namely they have an interlocking
relation . If the doorbell function is enabled, Small EP
monitoring cannot start . When unclear about which
parameter is incorrect, it is recommended to reset the
default parameters and start again .
Note: after the default parameter has been restored, all the other parameters will be
restored to the ex-factory value.
16 .
The alarm indicators or the zone indicators are always
on irrespective of the status:
This results from the overcurrent of the alarm probe
powered by the handset which automatically causes
a protection status . Disconnect the power after 10
seconds to eliminate the fault .
17 .
When the Small EP calls in, the handset returns to the idle
mode immediately:
This is the result of a short-circuit on the Small EP . Please
eliminate the problem and then reconnect .
18 .
The secondary EP can call the handset normally, but
when the main EP calls the handset, conversation is
possible but there is no video signal.
Make sure that main EP is connected to system out port
of riser shunt .
