Signal Strength Meter
The Signal Strength Meter (SSM) represents the relative strength of the
signal received by your phone. The SSM is displayed as a bar graph
following the letter S at the left side of the display. The S alone
represents the lowest strength with each additional bar representing a
stronger signal.
The SSM appears every time you turn your phone on, unless this feature is
turned off through the feature menu (refer to "Clear Memory Entries" on
Faxback Doc. # 34515). When the SSM blanks out of the display after eight
seconds, you can redisplay it at any time by pressing Clr or by opening or
closing the mouthpiece flip.
To best utilize the SSM, you should familiarize yourself with the relative
signal strength levels and their associated call placement and call-in
progress qualities.
To deactivate the SSM, see Faxback Doc. # 34515 , "Clear Memory Entries".
Display Battery Voltage Meter
Press Fcn, #1.
The Battery Voltage Meter (BVM) represents the current voltage level of the

letter B at the left side of the display.
Variables such as temperature, battery age, and charging conditions may
affect battery voltage.

and the displayed message Lo Bat. If the message is ignored, the phone
will automatically turn itself off as the battery approaches discharge.

The volume level is displayed as a bar graph following the letter V at the
left side of the display. The V alone represents the lowest volume setting
with each additional bar representing a higher volume setting.

Your telephone can operate over two different home systems, if you have

numbers.
While you may switch from one system to the other, only one of the two can
be active at any given time. Calls are placed and received through the
active system only.
If you have two phone numbers programmed into your phone, each time the
telephone is turned on, it displays a message indicating which home system
type and phone number is currently active.
The message shows the system type and phone number applied, as follows:
System Type and Phone Number Display A1
Non-wireline (type A) A1
with phone number 1
Non-wireline (type A) A2
with phone number 2
Wireline (type B) B1
with phone number 1
Wireline (type B) B2
with phone number 2
If a call is placed to the inactive phone number, the caller will receive
the recorded "Not in Service" message.
Illuminated Keypad
Your keypad lights whenever the phone is turned on or a call is received.
To help conserve battery power, the display and keypad lighting turns off
if no key is pressed. The keypad remains lit during menu use, and during
each call if the Automatic Display Timer is selected.
Antenna System
The antenna system of your telephone is designed for optimum performance
with the antenna extended.
There are two parts to the antenna, one internal and one retractable. This
allows you to receive calls on your telephone without having the antenna
extended. If No Svc flashes or lights steadily, you may be calling from a
fringe coverage area. It will be necessary to fully extend the antenna for
optimum performance.
