Do This
If this is a combination
extension (two devices,) be
sure the total of their Ringer
Equivlance Numbers
(REN) does not exceed
20. (See page 2-7.) If it
exceeds 20, unplug one of
the devices.
Remove the optional
device from the exten-
sion and plug in an
optional device that you
know rings properly.
First, make sure the
standard device in the
combination is plugged
into the correct slot on
the 267F2 bridging
adapter (see Figure 2-5).
If the extension still does
not work properly,
unplug the adapter from
the wall jack. Unplug the
phone's cord from the
adapter and plug it
directly into the wall jack.
Re-enter the date, day,
and time using System
Programming (#101,
#102 and #103).
Plug into the correct jack
(see Figure 2-5 on page
2-7).
First, unplug the bridging
adapter from the wall
jack. Then, unplug the
system phone from the
adapter and plug it into
the wall jack.
