DCS Manual Test Mode
Introduction
The phones are equipped with a Manual
Test Mode capability. This capability allows
service personnel to take control of the tele-
phone, and by entering certain keypad
sequences, make the telephone perform
desired functions. To enter the manual-test
mode, a Test SIM card (Part No 8102430Z01)
is required.
Test SIM Card Insertion/removal
The Test SIM card must be inserted into the
unit correctly to access Manual Test Mode.
The whole SIM card should slide completely
and securely into the slot at the base of the
phone. Ensure that the contacts of the card
face towards the front of the phone i.e.
towards the flip. See “SIM Card Insertion/
Removal” on page 12.
The sliding, card release button will move
upwards as the SIM card is inserted. When
the button reaches the top of its recess and
the card is flush with the base of the phone,
it is inserted correctly. To remove the SIM
card from the unit, push the sliding SIM
card release button downwards.
The card will then be pushed out far enough
to allow complete removal. The User Guide
contains full information about inserting
and removing the SIM card.
Accessing The Manual Test Mode
When the Test SIM card is in place, power
up the telephone. Once the initial automatic
‘wake up’ sequence has taken place
correctly, depress the # key (on the units
keypad) for three seconds. After three
seconds ‘TEST’ should appear in the display,
indicating that the unit is now in the Manual
Test Mode. Table 6: “DCS Test Commands”
on page 19 shows the available Manual Test
commands and their corresponding
results.If a customer should forget the secu-
rity code in their unit, it can only be read or
changed by using a Test SIM card.
