Testing Operation of the Hand-held Monitor
If you want to test the Hand-held Monitor display,
keypad, or internal electronics, select F2 (HHM
SELF-TEST) from the HHM Utilities menu. This
menu of tests appears:
F1:KEYPAD TEST
F2:DISPLAY TEST
F3:TEST INTRNALS
F4:
Testing the Keypad
Press F1 (KEYPAD TEST). The HHM prompts:
KEYPAD TEST
STRIKE ANY KEY
KEY=
MON/CFG KEY=CFG
Press any key you want to test. Each key press
is shown on the display. The HOME, D
MENU, and ON/OFF keys are tested by their
operation.
To test keyswitch operation, turn the key and
observe the bottom line of the display.
Press D MENU to perform another test, or
press HOME to return to the Home menu.
Testing the Display Screen
Press F2 (DISPLAY TEST) from the HHM Utilities
menu. The screen first displays uppercase letters
and special characters:
DISPLAY TEST

Next, a screen of lowercase letters appears,
followed by a continuous test pattern, which
checks pixel operation. When the test pattern is
finished, press DMENU to perform another HHM
test, or press HOME to return to the Home menu.

If an error occurs, one of the following messages
will appear instead.

E : R A M F A I L U R E
E : E P R O M F A I L U R E
E : E E P R O M F A I L U R E
E : C O M M E R R O R
Press the Clear key and try the test again. If the
message returns, replace the HHM. Otherwise,
continue.
An EEPROM failure will not prevent use of the
Hand-held Monitor. However, the HHM will not be
able to retain changes to its default configuration
through a power cycle.
The COMM ERROR message may indicate that
the Hand-held Monitor is not attached to a
correctly-terminated bus.
