The features of your EPABX require the use of
a Hook Flash (HF). This is performed by tapping
the hook switch of your extension for a period
of less than Flash time setted for that extension.
Care should be taken not to press the hook switch
for more than Flash time when a HF is desired.
If the exchange hook switch is pressed for longer
than flash time, it will register a "hang
up" or "reset". When disconnection
is desired care should be taken to press cradle
exceeding Flash time or otherwise call will go
on Hold and feature tone will be heard (this happens
most times when dialed number on CO. is busy and
one tries again dialing same number by disconnecting
and accessing CO. dials same number so disconnect
properly). Some telephone instruments have a built
in electronic flash key. It is advisable to use
the flash key instead of the hook switch in order
to register a "hook flash". This Hook
Flash time time is to be setted for each extension
individually as per the Instrument Flash Time
or Users normal usage of cradle switch. It can
done as follows; Lift the handset, on getting
dial tone,
Dial
and hang up.
Where
TT is time in milliseconds X 0.1, i.e. it ranges
from 400 to 990 milliseconds means user should
dial 40 to 99 for TT.
For
example, for 650 mSec,
Dial
and hang up
