If I'm thinking about the right laptop, it should be right next to the cd-rom. It should have a little screw undr the laptop that holds it in place. The battery itself slides into the side of the laptop.. Let me know if this solved the problem and good luck..

• Security-related information

1. Forced Power ON mode (All models)

Even when the security (Mask key) is approved, resetting

the unit while holding the ATT and Preset 4 keys makes it

possible to turn the power ON for 30 minutes. After 30

minutes have elapsed, it is not possible to return to the

previous condition unless the unit is reset again.

2. Method of registration of the security code after EEPROM

(Tuner Unit ***'y) replacement

(Code security model)

(1) Enter the test mode. (See " 1. How to enter the test

mode")

(2) Press the CLK key to enter the security registration

mode.

(3) Enter the code using the Preset 1/2/3/4 keys.

Example: To enter "3510"

• Press the Preset 1 key 4 times.

• Press the Preset 2 key 6 times.

• Press the Preset 3 key twice.

• Press the Preset 4 key once.

(4) Press and hold the DISP key for 3 seconds until

"APPROVED" is displayed.

(5) Exit from the test mode. (See " 2. How to exit from the

test mode")

(Note) All Clear is not applicable to the security code of

this model.

3. Simplified method of clearing the security code (K Type

only)

(1) While the code entry is requested, press and hold the

VOL UP key for 3 seconds while holding the DISP

key pressed. (This should turn "----" off.)

(2) Enter "KCAR" from the remote. (Same way as the 00

model)

Press the 5 key on the remote twice, then press the

Track Up key. (This enters "K".)

Press the 2 key on the remote 3 times, then press the

Track Up key. (This enters "C".)

Press the 2 key on the remote once, then press the

Track Up key. (This enters "A".)

Press the 7 key on the remote twice, then press the

Track Up key. (This enters "R".)

(3) The security code is cleared and the unit enters the

ALL OFF mode.

(4) If you commit a mistake in the code entry, the unit

enters the code request mode again.

4. Method of writing the Mask key while the EEPROM is in

the initial status

(1) Enter the test mode. (See " 1. How to enter the test

mode")

(2) Press the CLK key to enter the Mask key registration

mode. "TRANSMIT1" should be displayed now. The

display at this time should show " < > " in place of " [ ]

".

(3) Point the Mask key remote toward the light sensor,

and press and hold its key for more than 0.5 second.

(4) When "TRANSMIT2" is displayed, press and hold the

key on the Mask key remote for more than 0.5 second

again. The first and second counter codes are not

compared at this time.

(5) When "APPROVED" is displayed, the write operation

is complete. Now the demonstration mode is initiated

and the test mode is terminated.

(Note) In the same way as previous models, if 30 minutes

have elapsed with no code written, an error occurs

and the power is turned OFF.

5. Method of initializing the Mask key

(How to reset the unit from the Mask key approved condition

to the factory condition)

(1) Enter the test mode. (See " 1. How to enter the test

mode")

(2) "TRANSMIT1" is displayed and the Mask key entry

request mode is initiated.

The display at this time should show " ∗ ∗ " in place of

" [ ] ".

(3) Press and hold the key on the Master key remote for

more than 3 seconds.

(4) When "TRANSMIT2" is displayed, press and hold the

key on the Master key remote for more than 3 seconds

again.

(5) When "APPROVED" is displayed, the Mask key is

cleared, the demonstration mode is initiated, the test

mode is terminated and the unit returns to the factory

condition.

6. Method of clearing all Mask key-related data

(1) Enter the test mode. (See " 1. How to enter the test

mode")

(2) Press the CLK key to enter the Mask key registration

mode. "TRANSMIT1" should be displayed now.

(3) Point the Master key remote toward the light sensor,

and press and hold its key for more than 3 seconds

(until the level display shows the full condition).

(4) When "TRANSMIT2" is displayed, hold the key on the

Mask key remote for more than 3 seconds again.

If "TRANSMIT1" is displayed in place of "TRANSMIT2",

restart the procedure from step (3).

(5) When "APPROVED" is displayed, all security data is

cleared and the unit returns to the condition before
Mask key writing with the EEPROM in the initial status
