– SID SCRN ON: Your phone will attempt to select
one of the dealer programmed (e.g. low cost) pre-
ferred types of networks. However, you may experi-
ence poor call quality if only distant networks of this
type are available. If no preferred service is available
on this type of network, then the message
SID
SCRN BARRED will appear, and the NO part of the
NO SVC indicator will flash. In this instance, you may
be able to make emergency calls (depending on
the network and the emergency number pro-
grammed into your phone) but will not be able to
make any other calls, or receive any calls.
Note: When SID SCRN is set to on, ‘System Select
(Menu 1)’ will automatically be set to “Both Systems”.
– SID SCRN OFF: You will always obtain the highest-
quality call possible. However, the phone may roam,
and the cost of calls when roaming may be greater
(refer to ‘System Select (Menu 1)’, page 33).

Hook Flash Function and 3 Party Calls
Your cellular system may offer a ‘hook flash’ (call
waiting) service. This system feature lets you accept a
second call when you already have a call in progress.
Your cellular system may also offer a ‘3 Party Call’
service. This system feature lets you make a second
call when you already have a call in progress. It also
allows you to link the first and second call so that all
3 parties can converse.
Contact your cellular service provider for further
details.
