LCD Test

When you press the 2 on the
DTMF keypad, the LCD displays
a pattern of dark characters.
Missing dots, if any, will be
evident.
When you press the 3 on the

supported by the set. Press 3

Memory Tests

Pressing 4 on the numeric keypad

tests, performing memory and line
tests in order.
The first of these tests writes to

When the RAM test terminates
successfully, the Digital Set goes

An error in this test is reported by
