User Manual
LCD DISPLAY
The LCD displays call, programming and signal strength information
- see Figure 10
.
Received Signal Strength
The Received Signal Strength is displayed by the first 11 characters (from left to right) in the
Indicator Row
- see Figure 10
. Received signal strength can be displayed by either a direct
readout of the signal strength in dBm or a signal strength bar graph. This setting is programma-
ble. See the
Phonecell SX4
P
Programming
section of this manual.
•
Direct Readout
displays the signal strength as "
-XXXdBm
", where
XXX
refers to the signal
strength. The SX4
P
monitors signal strength in the range of -110dBm to -48dBm, where -
110dBm indicates no signal and -48dBm indicates the strongest signal. The factory setting is
the Direct Readout Mode.
•
Signal Strength Bar Graph
displays the signal strength as a series of solid block characters.
The stronger the signal, the more characters are displayed from left to right. To set Bar Graph
mode, see the
Phonecell SX4
P
User-Programming Commands
section of this manual.
NOTE:
The 12th character (from left to right) is used as a separator only and does not provide
information
- see Figure 10
. A "
||
" character is displayed and is always displayed.
Call-Timer
The Call Timer icon appears when the SX4
P
begins a connected phone call. The call timer
begins as all zeros and increments every subsequent second. The timer will roll over back to
0:00 after 99:59. When the handset is placed on-hook (ends call), the call timer stops and dis-
plays the accumulated call time for thirty seconds. The Call Timer icon is then turned off.
If the handset goes off-hook and a digit is pressed within the thirty second period, the call time
display will immediately turn blank.
