-
- Range is advertised as 1000 feet, but in 'real world' urban
- conditions, expect anywhere from 100 - 300 foot 'usable' range. This
- figure is dependent upon a myriad of conditions from location of base
- unit, type of building construction, portable battery level and
- interference from other phones and devices that share the frequencies
- that the phones use.

-
- Security codes are used by the phone to make it more unlikely that
- others can gain access to your line, by using a handset on the same
- frequency as your unit. Security codes also can be used to keep your
- portable from ringing when a neighbor's phone is called. They have
- nothing to do with overhearing or being overheard.
-

-
- None. Channels are the actual radio frequuencies over which the call
- is transmitted, security codes are information sent over those
- channels as described above.
-

- > outside and wait for it to ring? Does it have to stand up in the base?
-
- No need to keep it in the base, except for charging. However, it is
- best NOT to keep charging and recharging. Better to use the batteries
- until the battery-low light comes on. Continued short charges can
- cause the battery to aquire a short-memory, and begin to lose it's
- ability to stay charged for a full term.

-
- The interference is caused BY the computer's cpu clock, and causes the
- phone to whistle and whine. The phone will not bother the computer.
-
- > 6) Finally is this a particularly good or bad phone?
-
- I have heard good things about the Sony. Never owned one.
