Radio Shack CT-503 - Manual (Page 16)

16
Notes:
• If few or no bars appear (meaning the signal strength is
weak) and you want to make or receive a call, move the
phone to a different location so the signal strength
increases.
• When all other display characters disappear to conserve
battery power, the signal strength meter flashes and
scrolls its bars.
If NS (no service) appears on the upper left side of the dis-
play, the phone is outside the cellular service area and you
cannot make or receive calls until you reach an area with ser-
vice your phone can use.
MAKING A CALL
1. Extend the antenna, flip open the cover, and be sure the
phone is on ( on and other indicators appear).
2. Press the number keys to enter the phone number you
want to dial (including the area code, if necessary). The
numbers appear on the display as you press them.
Notes:
• If you make a mistake, repeatedly press to delete
one digit at a time, or hold down to delete all dig-
its.
• The phone can display up to 10 characters at once. If
you enter (or display a message containing) more
than 10 characters, the characters automatically scroll
off the left side of the display. Press
at any time to
recall the overflow characters. See “Any Number
Longer Than 10 Digits” on Page 23.
